We look at the division of 31172 by 99 
We want to divide 31172 by 99.

On to step 1:
99 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 99

Moving on to step 2:
99 goes into 31 0 times with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Append the next digit (1) from the dividend to 31 and continue with: 311 / 99

Going ahead to step 3:
When dividing 311 by 99, we get 3 with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 297 away from 311, we end up with 14.
Bring next digit (7) of the dividend behind the 14 and repeat the process: 147 / 99

Step 4:
99 goes into 147 1 times with a remainder of 48.
The next digit of our result is 1. 
Result so far: 31.0
The remainder is 48 after subtracting 99 from 147.
Include the next digit (2) from the dividend after 48, then repeat: 482 / 99

On to step 5:
99 can be fit into 482 4 times, resulting in a remainder of 86.
The next digit of our result is 4. 
Result so far: 314.0
Deduct 396 from 482 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 6:
When dividing 860 by 99, we get 8 with a remainder of 68.
The next digit of our result is 8. 
Result so far: 314.8
If we subtract 792 from 860, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 7:
If we divide 680 by 99, we get 6 and a remainder of 86.
Put 6 as the next digit of the answer. 
Result so far: 314.86
If we take 594 away from 680, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 8:
860 divided by 99 is 8 with a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 314.868
If we take 792 away from 860, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 9:
99 goes into 680 6 times with a remainder of 86.
The next digit of our result is 6. 
Result so far: 314.8686
Subtracting 594 from 680 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 10:
99 can be fit into 860 8 times, resulting in a remainder of 68.
Put 8 as the next digit of the answer. 
Result so far: 314.86868
If we subtract 792 from 860, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 11:
99 can be fit into 680 6 times, resulting in a remainder of 86.
The number 6 becomes the next digit in our result. 
Result so far: 314.868686
The remainder is 86 after subtracting 594 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 12:
860 divided by 99 is 8 with a remainder of 68.
The next digit of our result is 8. 
Result so far: 314.8686868
The remainder is 68 after subtracting 792 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 13:
680 divided by 99 is 6 with a remainder of 86.
The number 6 becomes the next digit in our result. 
Result so far: 314.86868686
If we take 594 away from 680, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

In conclusion, the division gives 314.86868686 with a balance of 8.6e-08.
