We look at the division of 99647109 by 831 
Let's see how many times 831 fits into 99647109.

Step 1:
9 divided by 831 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 831

Let's proceed to step 2:
The number 831 fits into 99 0 times, leaving a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Include the next digit (6) from the dividend after 99, then repeat: 996 / 831

On to step 3:
831 goes into 996 1 times with a remainder of 165.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 831 from 996 to get 165.
Fetch the next digit (4) from the dividend, attach it to 165 and continue: 1654 / 831

Going ahead to step 4:
The number 831 fits into 1654 1 times, leaving a remainder of 823.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 831 away from 1654, we end up with 823.
Include the next digit (7) from the dividend after 823, then repeat: 8237 / 831

On to step 5:
831 can be fit into 8237 9 times, resulting in a remainder of 758.
Write down 9 as next digit of the result. 
Result so far: 119.0
Subtracting 7479 from 8237 leaves us with 758.
Include the next digit (1) from the dividend after 758, then repeat: 7581 / 831

Going ahead to step 6:
831 can be fit into 7581 9 times, resulting in a remainder of 102.
Use 9 as the next digit of our solution. 
Result so far: 1199.0
The remainder is 102 after subtracting 7479 from 7581.
Take the next digit (0) from the dividend and append it to 102, then repeat: 1020 / 831

Moving on to step 7:
The number 831 fits into 1020 1 times, leaving a remainder of 189.
Record the quotient 1 as the next digit in the result. 
Result so far: 11991.0
If we subtract 831 from 1020, we get 189.
Take the next digit (9) from the dividend and append it to 189, then repeat: 1899 / 831

Advancing to step 8:
831 goes into 1899 2 times with a remainder of 237.
Use 2 as the next digit of our solution. 
Result so far: 119912.0
Deduct 1662 from 1899 and we're left with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Going ahead to step 9:
2370 divided by 831 is 2 with a remainder of 708.
Record the quotient 2 as the next digit in the result. 
Result so far: 119912.2
Subtract 1662 from 2370 to get 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Advancing to step 10:
The number 831 fits into 7080 8 times, leaving a remainder of 432.
Record the quotient 8 as the next digit in the result. 
Result so far: 119912.28
Deduct 6648 from 7080 and we're left with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Moving on to step 11:
When dividing 4320 by 831, we get 5 with a remainder of 165.
Write down 5 as next digit of the result. 
Result so far: 119912.285
Subtract 4155 from 4320 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Let's proceed to step 12:
When dividing 1650 by 831, we get 1 with a remainder of 819.
Write down 1 as next digit of the result. 
Result so far: 119912.2851
The remainder is 819 after subtracting 831 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8190, and continue the process.

On to step 13:
The number 831 fits into 8190 9 times, leaving a remainder of 711.
The next digit of our result is 9. 
Result so far: 119912.28519
The remainder is 711 after subtracting 7479 from 8190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7110, and continue the process.

On to step 14:
If we divide 7110 by 831, we get 8 and a remainder of 462.
The number 8 becomes the next digit in our result. 
Result so far: 119912.285198
The remainder is 462 after subtracting 6648 from 7110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

On to step 15:
If we divide 4620 by 831, we get 5 and a remainder of 465.
Write down 5 as next digit of the result. 
Result so far: 119912.2851985
Subtract 4155 from 4620 to get 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Let's proceed to step 16:
The number 831 fits into 4650 5 times, leaving a remainder of 495.
Use 5 as the next digit of our solution. 
Result so far: 119912.28519855
If we subtract 4155 from 4650, we get 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

The final outcome is 119912.28519855, with a leftover of 4.95e-07.
