Write down 7 as next digit of the result. 
Result so far: 9307.0
The remainder is 88 after subtracting 3997 from 4085.
Take the next digit (8) from the dividend and append it to 88, then repeat: 888 / 571

On to step 8:
571 can be fit into 888 1 times, resulting in a remainder of 317.
The next digit of our result is 1. 
Result so far: 93071.0
Deduct 571 from 888 and we're left with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Advancing to step 9:
571 goes into 3170 5 times with a remainder of 315.
The next digit of our result is 5. 
Result so far: 93071.5
Deduct 2855 from 3170 and we're left with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Going ahead to step 10:
571 goes into 3150 5 times with a remainder of 295.
Write down 5 as next digit of the result. 
Result so far: 93071.55
If we subtract 2855 from 3150, we get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

After the division, we end up with 93071.55 and a remainder of 0.295.
