Dividing numbers by mind or with the calculator becomes more complicated if you use fractions or decimals in arithmetic. When you divide an integer numerator by a decimal denominator, you will need to add decimal numbers to get the quotient.

Steps

Method 1 of 2: Part 1: Converting the Numbers

Divide a Whole Number by a Decimal Step 1

Step 1. Write your division on a piece of paper

Use a pencil if you want to be able to correct the work you are about to do. For example, 8/0, 62.

  • The numerator is the number you are dividing. It is the first number of the fraction.
  • The denominator is the number you are dividing by. It is the second number of the fraction.
  • The quotient is the result.

Step 2. Any changes you make to the decimal number in the denominator (0

62), you will also need to do this in the numerator (8).

This way you will make sure that the value does not change.

Step 3. Write the numerator with decimals after the whole number

For example, 8.00. This is a good way to see how an integer can work as a decimal, without changing its value.

Step 4. Move the numerator decimal 2 places to the right to make it an integer

For example, 0, 62 becomes 62.

Step 5. The numerator also moves 2 places

For example, 8.00 becomes 800.

Step 1. Rewrite your division with integers

For example, 800 / 62. 8/0, 62 is the same division of 800/62!

Step 3. Get the quotient

The answer in our example is 12, 9. You don't have to add decimal places in the answer because the value of the first division and the second division are exactly the same!
