8 goes into 56 7 times with a remainder of 0.
Write down 7 as next digit of of the result. 
Result so far: 727
Subtract 56 from 56 to get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 8

Step 5:
8 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of of the result. 
Result so far: 7270
