With Long Division

The long division method is very simple. All the fractions can be written as a division expression.


The numerator is divided by the denominator to get the decimal value of a fraction. Here 7 is the numerator and 8 is the denominator.

To make 7 divisible by 8, add 0 to 7 to make it 70. Remember to place a decimal point in the quotient when this is done.


As we get the remainder 0 in the third step, we cannot divide further.

The answer is 0.875.

Without long division

The rule to directly convert a fraction to a decimal is

  • The denominator should be a number with 1 followed by one or more zeros. Or the denominator should be a number that can be multiplied by a suitable number to make it 10, 100, 1000 etc.
  • The number of zeros in the denominator is the number of digits the decimal point has to be shifted to the left in the numerator.

Here we have 8 in the denominator, to which 125 can be multiplied to get 1000. The same value should be multiplied by the numerator also as given below.



Here are some common terms you should be familiar with.

  • In the fraction$$ \frac{7}{8}$$, the number 7 is the dividend (our numerator)
  • The number 8 is our divisor (our denominator)
