Use 5 as the next digit of our solution. 
Result so far: 25059.915
The remainder is 635 after subtracting 4155 from 4790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Going ahead to step 12:
831 goes into 6350 7 times with a remainder of 533.
Write down 7 as next digit of the result. 
Result so far: 25059.9157
Subtracting 5817 from 6350 leaves us with 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Going ahead to step 13:
831 can be fit into 5330 6 times, resulting in a remainder of 344.
The number 6 becomes the next digit in our result. 
Result so far: 25059.91576
Deduct 4986 from 5330 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Advancing to step 14:
3440 divided by 831 is 4 with a remainder of 116.
Use 4 as the next digit of our solution. 
Result so far: 25059.915764
The remainder is 116 after subtracting 3324 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 15:
When dividing 1160 by 831, we get 1 with a remainder of 329.
Put 1 as the next digit of the answer. 
Result so far: 25059.9157641
