Long division is the process of dividing large numbers into steps or parts, dividing the problem into a sequence of easier steps. Long division to decimal is similar to the long division to whole numbers, except for the way we manage the decimal point. The secret to performing long division to decimal places is to add zeros after the decimal point. For example, 140 is the same as 140.00. We can include as many zeroes as we wish after the decimal point without changing the value of the number.
Let us learn more about how to do the long division with decimals by reading the content given below, which enables us to understand better.
Long Division to Decimal Steps
Long division to decimal can be easily done just as the normal long division. The following steps explain how to do long division with decimal points.
Step 1: The first step is to write the number in standard form. Start by dividing the whole number part by the given divisor.
Step 2: Place the decimal point in the quotient above the decimal point of the dividend. Bring down the tenth digit for continuing the further division process.
Step 3: Divide and bring down the other digits such as hundredths, thousandth, etc in a sequence. Divide until you get the 0 in the remainder. Hence, you will find the same number of decimal points are placed in the quotient as in the dividend
Long Division to Decimal When Divisor is Not a Whole Number
The following steps with example explain long division to decimal when the divisor is not a whole number:
Divide 16.9 by 6.5
1. As the divisor is not a whole number, we will move the decimal point to the right side to convert it into a whole number and also move the decimal point in the dividend one place to the right as shown below.
2. Divide usually as a whole number. The divisor 65 goes into the dividend 139, 2 time(s), with 39 left as a remainder.
3. To continue the division process, add zero to the right of the decimal point in the dividend. Further, bring down the 0 and place it to the end of 39, making it 390.
4. 65 goes into the 390, six times with a remainder of 0. We will write 6 in the quotient just above the zero and place the decimal point in the quotient above the decimal point of the dividend as shown below.
Hence, 16.9 when divided by 6.5 gives a quotient of 2.6 and remainder 0.
Long Division 3 Examples With Solutions
1. Hitesh Wants to Know the Long Division Steps that Need to be Followed to Obtain the Result of 1.683 ÷ 0.09. Can You Help Him to Find the Result?
Following are the steps that Hitesh needs to follow to get a result of 1.683 ÷ 0.09.
First, the divisor will be converted into the whole number by multiplying the divisor by 100 (0.09 100 = 9). Further, we will also multiply the dividend by 100 (1.683 100 = 168.3) to get the decimal point in the same number of places.
Now, the division will be performed in the following way:
Hence, 168.3 0.09 = 18.7
2. Ronak Distributed 75 Chocolates Among 3 of his Friends. How Many Chocolates Did he Distribute to Each Friend?
Total Number of Chocolates = 75
Number of Friends = 3
To find the number of chocolates distributed to each friend, we have to divide 75 by 3 because an equal number of chocolates are distributed to each friend.
Hence, the number of chocolates distributed to each friend is 25.
Points to Remember
There is a certain procedure of dividing the decimals by the whole number.
The first step is to write the division expression in a completely standard form.
Then the decimal’s whole number has to be divided by the divisor.
The decimal point has to be placed above the quotient above the dividend’s decimal point and bring down the tenth digit.
Write 0 in the quotient in front of the tenth digit if the tenth digit of the dividend is not divisible by the divisor.
In order to attain 0 in the reminder, zeros must be added to the dividend, if not required then proceed as usual.
Dividing a decimal by 10 will move the decimal point to one place towards the left,
In order to Divide 5 by 100, place the decimal point in the numerator like 5/100 = 0.05. It will mean that the decimal point will shift to the left by two places since 100 has two 0’s.
Dividing 31 by 100 where it is written as 31/100, the denominator has two 0’s which is why the decimal point has to be placed in two places like 0.31.
Dividing decimals is like dividing whole numbers where the decimal point has to be taken into account along with its placement.
It has two ways for dividing, namely, dividing decimals by whole numbers or division of decimals by another decimal number.
Decimals may also be divided by 10, 100, and 1000.
There are certain rules that are to be followed during the division of decimals.
A division expression has four parts namely, dividend, divisor, quotient, and remainder.
