How To Do Long Division For Class 3 With Step By Step Solved Examples

Long division is a method in Mathematics for dividing big numbers into steps or parts, breaking the division questions into smaller stages. It is the most commonly used approach for dividing problems and makes it easier for kids to learn about the division better. Examine the following long division to find the divisor, dividend, quotient, and remainder. Before executing it, we must be aware of the crucial aspects of long division.


Long Division with Single-Digit Divisor

Long division is done like simple division. When the divisor is a single digit, it is easy to divide the dividend. You can learn and practice the steps that need to be followed while long division is given.


Step One: Check the first unit of the dividend whether it is divisible by the divisor or not.


Step Two: If the first unit is less than the divisor, take the second digit into account.


Step Three: Then, find the suitable multiple and subtract the numbers. After subtraction brings down the next digit and then again repeat the above steps till you get the remainder as 0 or a number that further cannot be divided.

Long Division with Two-Digit Divisor

The long division with a two-digit divisor can be done using the same steps that are mentioned above. In this, the only change is that in the dividend we take the first two digits of the number to subtract it from the multiple of the divisor. And the rest of the steps are the same.

Long Division with Remainders

The long division ends when there is a remainder left that cannot be further divided by the divisor or the value of the number is less than the divisor itself. Like in the above-mentioned 435 divided by 4 sample questions, after taking down the last digit 5 to be subtracted we are left with 3. As 3 is less than the divisor 4 so we will now conclude the long division as there are no more digits present in the dividend, which can be used to reduce it. So, we are left with 3 as the remainder.


Long Division without Remainders

Long division without remainders means that the remainder is 0 or the last number to be subtracted by the multiple of the divisor was the same giving us the remainder 0. In an example of a division of 126 by 2, we will get 63 as the quotient. As the last digit 6 is completely divisible by 2 we get the remainder as 0 making it a long division without remainder.


Conclusion

The long division is similar to the standard division. The division consists of dividend, divisor, quotient, and the remainder where the divisor can be single-digit, double-digit, or triple-digit. The remainder can be zero or a number that is less than the divisor. If the dividend does not get divided fully or does not have a remainder as 0, then the division can continue further by using a decimal point. The divisor can be single-digit, two-digit, or three-digit.


Long Division Worksheets

1. Divide 432 by 15.

  1. 27

  2. 28

  3. 29

  4. 30

Ans: 28

Explanation: In this, we will take the first two digits of the dividend as our divisor is two digits. A multiple of 15 which is less than or equal to 43 is found and then it is subtracted. The remainder along with the next digit of the dividend is then evaluated and subtracted again.

2. Divide 1850 by 12 using long division.

  1. 144

  2. 154

  3. 164

  4. 174

Ans: 154

Explanation: Step one: As 18 is a little greater than the divisor itself so we will subtract it by 12. We get 6 as the remainder.


Step Two: Bring down 5 and the new number becomes 65 which can be subtracted from 60 which is a multiple of 12.


Step Three: Now bring down 0 and subtract it with the multiple of 12. There is a remainder left as 2. We get our answer as 154 the quotient.

3. What is the value of the remainder when the division ends without any remainder left?

  1. 1

  2. 0

  3. not defined

Ans: 0


FAQs on Long Division For Class 3 Complete Guide With Simple Steps

1. What is long division for Class 3?

Long division for Class 3 is a step-by-step method used to divide larger numbers into smaller equal parts. It helps students divide numbers that are too big for simple mental division. In long division, we use four main steps:

  • D – Divide
  • M – Multiply
  • S – Subtract
  • B – Bring down
This method is commonly used to solve division problems with 2-digit or 3-digit numbers.

2. How do you do long division step by step?

To do long division step by step, follow the Divide, Multiply, Subtract, Bring Down method. Example: Divide 84 by 4.

  • Step 1: 8 ÷ 4 = 2
  • Step 2: 2 × 4 = 8
  • Step 3: 8 − 8 = 0
  • Step 4: Bring down 4
  • Step 5: 4 ÷ 4 = 1
The final answer is 21. This is called the quotient.

3. What is the formula for long division?

The formula for long division is Dividend ÷ Divisor = Quotient + Remainder. It can also be written as:

  • Dividend = (Divisor × Quotient) + Remainder
For example, in 23 ÷ 5:
  • 5 × 4 = 20
  • Remainder = 3
So, 23 = (5 × 4) + 3.

4. What is the difference between divisor, dividend, and quotient?

In division, the dividend is the number being divided, the divisor is the number we divide by, and the quotient is the answer. Example: In 36 ÷ 6 = 6:

  • 36 is the dividend
  • 6 is the divisor
  • 6 is the quotient
If something is left over, it is called the remainder.

5. How do you do long division with remainder?

Long division with remainder means some number is left after dividing completely. Example: Divide 29 by 4.

  • 4 × 7 = 28
  • 29 − 28 = 1
The answer is 7 remainder 1. Here, 7 is the quotient and 1 is the remainder.

6. Can you give an example of long division for Class 3?

Yes, here is a simple long division example: Divide 96 by 3.

  • 9 ÷ 3 = 3
  • 3 × 3 = 9
  • 9 − 9 = 0
  • Bring down 6
  • 6 ÷ 3 = 2
The final answer is 32. This means 96 divided by 3 equals 32.

7. What are the steps of long division?

The steps of long division are Divide, Multiply, Subtract, and Bring Down. These steps are often remembered as DMSB.

  • Divide the first number
  • Multiply the answer with divisor
  • Subtract the result
  • Bring down the next digit
Repeat the steps until all digits are used.

8. Why is long division important in Class 3?

Long division is important in Class 3 because it helps students divide larger numbers correctly and understand equal sharing. It builds a strong base for:

  • Learning multiplication and division facts
  • Solving word problems
  • Understanding fractions and decimals later
It improves logical thinking and number skills.

9. What are common mistakes in long division?

Common mistakes in long division include skipping steps or incorrect subtraction. Students should avoid:

  • Dividing without checking multiplication facts
  • Forgetting to bring down the next digit
  • Making subtraction errors
  • Writing the quotient in the wrong place
Checking each DMSB step carefully helps prevent mistakes.

10. How do you check your long division answer?

You can check a long division answer by using the formula Dividend = (Divisor × Quotient) + Remainder. Example: 45 ÷ 5 = 9.

  • 5 × 9 = 45
  • No remainder
Since the result equals the dividend, the answer is correct. This method helps verify long division problems easily.
