We look at the division of 831105 by 87 
We want to divide 831105 by 87.

On to step 1:
8 divided by 87 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 87

Let's proceed to step 2:
When dividing 83 by 87, we get 0 with a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Bring next digit (1) of the dividend behind the 83 and repeat the process: 831 / 87

On to step 3:
The number 87 fits into 831 9 times, leaving a remainder of 48.
The next digit of our result is 9. 
Result so far: 9.0
If we take 783 away from 831, we end up with 48.
Grab the next digit (1) from the dividend, add it to 48, then carry on: 481 / 87

On to step 4:
87 can be fit into 481 5 times, resulting in a remainder of 46.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
If we subtract 435 from 481, we get 46.
Bring next digit (0) of the dividend behind the 46 and repeat the process: 460 / 87

Going ahead to step 5:
460 divided by 87 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 955.0
Deduct 435 from 460 and we're left with 25.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 87

Step 6:
The number 87 fits into 255 2 times, leaving a remainder of 81.
Write down 2 as next digit of the result. 
Result so far: 9552.0
If we subtract 174 from 255, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 7:
The number 87 fits into 810 9 times, leaving a remainder of 27.
The next digit of our result is 9. 
Result so far: 9552.9
The remainder is 27 after subtracting 783 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 8:
87 can be fit into 270 3 times, resulting in a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 9552.93
If we take 261 away from 270, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
The number 87 fits into 90 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 9552.931
If we take 87 away from 90, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
87 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 9552.931
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
When dividing 300 by 87, we get 3 with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 9552.93103
The remainder is 39 after subtracting 261 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 12:
390 divided by 87 is 4 with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 9552.931034
The remainder is 42 after subtracting 348 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 13:
87 goes into 420 4 times with a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 9552.9310344
Subtracting 348 from 420 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

In conclusion, the division gives 9552.9310344 with a balance of 7.2e-07.
