The division of a whole number by a decimal number looks difficult until you understand the problems’ tricks. Decimal is a part of the number system to express the place value like tenth, hundredths, thousandths, etc. The operation of decimal numbers is similar to the operation of the whole numbers and the fractional part is separated by a dot (decimal point). Learn more about the division of a whole number by a decimal with some examples. Solve the given problems and enhance your skills and become a master in maths.

Division of a Whole Number by Decimal – Definition
To divide a whole number by a decimal, we have to divide the same as we would divide for the whole numbers and then place the decimal point in the result.
Rules for Dividing Whole Numbers by Decimals
1. To divide the whole numbers by a decimal number we have to use the long division method ignoring the decimal points.
2. We have to divide the numbers as if it is a whole number.
3. Divide the number till the remainder leaves 0.
4. We have to place the decimal value point in the result from the left. Therefore we get the solution when the whole number is divided by decimal number.
How to Divide Whole Numbers by Decimals?
Dividing a whole number by a decimal number is similar to the regular division. Here the dividend is the whole number and a divisor is a decimal number. The division of a whole number by a decimal is simply done by following some steps.
Step 1. Ignore the decimal and divide normally until you get the remainder as 0.
Step 2. After the division operation place the decimal point in the quotient in the same position as given in the divisor. Where the decimal is placed according to the dividend.
Let us consider an example to know how to divide a whole number by a decimal.
15 divided 0.2
Solution:
First, multiply the 0.2 by 10
0.2 × 10 = 2
Also multiply 15 by 10
15 × 10 = 150
So, 15 ÷ 0.2 becomes 150 ÷ 2
150 ÷ 2 = 75
Therefore the answer is 15 ÷ 0.2 = 75
Examples on Division of a Whole number by a Decimal
Check out the below questions and answers on the Division of a whole number by a decimal number. This will help the students in 5th grade to understand the difference between whole number division and decimal with whole number difference. Also, you can solve different types of problems on it.
Example 1.
Division of whole number 320 by 0.6?
Solution:
Ignore the decimal and divide normally until you get the remainder as 0.
Count the number of decimal digits in the divisor.
32 ÷ 0.6
We observe that after decimal there is 1 number.
Add as many zeros to the dividend and remove the decimal.
320 ÷ 6
Therefore 32 ÷ 0.6 = 53.3
Example 2.
Division of a whole number 212 by 0.02?
Solution:
Ignore the decimal and divide normally until you get the remainder as 0.
Count the number of decimal digits in the divisor.
212 ÷ 0.02
We observe that after decimal there is 2 number.
Add as many zeros to the dividend and remove the decimal.
21200 ÷ 2
Therefore 212 ÷ 0.02 = 10600
Example 3.
Division of a whole number 474 ÷ 1.32?
Solution:
Ignore the decimal and divide normally until you get the remainder as 0.
Count the number of decimal digits in the divisor.
474÷ 1.32
We observe that after decimal there is 2 number.
Add as many zeros to the dividend and remove the decimal.
47400 ÷ 132
Therefore 474 ÷ 1.32 = 359.09
Example 4.
Division of a whole number 100 by 2.5
Solution:
Ignore the decimal and divide normally until you get the remainder as 0.
Count the number of decimal digits in the divisor.
100 ÷ 2.5
We observe that after decimal there is 1 number.
Add as many zeros to the dividend and remove the decimal.
100 ÷ 25
Therefore 100 ÷ 25 = 40
Example 5.
Division of a whole number 2635 ÷ 1.320?
Solution:
Ignore the decimal and divide normally until you get the remainder as 0.
Count the number of decimal digits in the divisor.
2635 ÷ 1.320
We observe that after decimal there is 3 number.
Add as many zeros to the dividend and remove the decimal.
2635000÷ 1320
Therefore 2635 ÷ 1.320 = 1996.21
