We're dividing 87091193 by 831 
Our goal is to divide 87091193 by 831.

Advancing to step 1:
8 divided by 831 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 831

Advancing to step 2:
When dividing 87 by 831, we get 0 with a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Bring next digit (0) of the dividend behind the 87 and repeat the process: 870 / 831

Moving on to step 3:
When dividing 870 by 831, we get 1 with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 831 from 870, we get 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 831

Step 4:
If we divide 399 by 831, we get 0 and a remainder of 399.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 399 to get 399.
Include the next digit (1) from the dividend after 399, then repeat: 3991 / 831

Advancing to step 5:
3991 divided by 831 is 4 with a remainder of 667.
The next digit of our result is 4. 
Result so far: 104.0
Subtract 3324 from 3991 to get 667.
Grab the next digit (1) from the dividend, add it to 667, then carry on: 6671 / 831

Going ahead to step 6:
If we divide 6671 by 831, we get 8 and a remainder of 23.
Write down 8 as next digit of the result. 
Result so far: 1048.0
If we subtract 6648 from 6671, we get 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 831

Going ahead to step 7:
239 divided by 831 is 0 with a remainder of 239.
Put 0 as the next digit of the answer. 
Result so far: 10480.0
Deduct 0 from 239 and we're left with 239.
Include the next digit (3) from the dividend after 239, then repeat: 2393 / 831

Going ahead to step 8:
831 can be fit into 2393 2 times, resulting in a remainder of 731.
Put 2 as the next digit of the answer. 
Result so far: 104802.0
Subtract 1662 from 2393 to get 731.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7310, and continue the process.

On to step 9:
The number 831 fits into 7310 8 times, leaving a remainder of 662.
Write down 8 as next digit of the result. 
Result so far: 104802.8
The remainder is 662 after subtracting 6648 from 7310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Step 10:
If we divide 6620 by 831, we get 7 and a remainder of 803.
Write down 7 as next digit of the result. 
Result so far: 104802.87
Deduct 5817 from 6620 and we're left with 803.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8030, and continue the process.

Step 11:
831 goes into 8030 9 times with a remainder of 551.
Write down 9 as next digit of the result. 
Result so far: 104802.879
If we take 7479 away from 8030, we end up with 551.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Advancing to step 12:
The number 831 fits into 5510 6 times, leaving a remainder of 524.
Use 6 as the next digit of our solution. 
Result so far: 104802.8796
Subtracting 4986 from 5510 leaves us with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

On to step 13:
5240 divided by 831 is 6 with a remainder of 254.
Write down 6 as next digit of the result. 
Result so far: 104802.87966
Deduct 4986 from 5240 and we're left with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

In conclusion, the division gives 104802.87966 with a balance of 0.000254.
