You already know how to divide and write the remainder of a division problem as a fraction.
How did we get 
as the remainder for the problem above? When we divide 8 by 5 (8 ÷ 5), 5 goes into 8 one time and there's 3 left over. That's .
Instead of writing the remainder as a fraction, we can write it as a decimal number. How do we do that?
Let's look at our example above. It's 8 divided by 5:
First, we put a decimal point after the 8. Then we put a decimal point in the answer right above the other decimal point. We can add zeros to the 8 without changing its value. Your problem will look like this:
Now we divide. Five goes into 8 one time. We write 1 above the 8. We subtract 5 from 8 and get 3 left over (8 - 5 = 3). Bring down a zero. Five goes into 30 six times. There is no remainder, so we can stop. We don't have to use the other zeros to keep dividing. As soon as we have no remainder, we can stop. The answer is 1 and 6 hundredths. That's the same value as 
! The fraction and the decimal number are equal.
Now, that's really simple!
