Put 1 as the next digit of the answer. 
Result so far: 7949.1
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
80 divided by 72 is 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 7949.11
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.
