We look at the division of 831455 by 12 
We're looking to find how many times 12 goes into 831455.

Step 1:
12 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 12

Advancing to step 2:
12 can be fit into 83 6 times, resulting in a remainder of 11.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 72 from 83 leaves us with 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 12

Let's proceed to step 3:
If we divide 111 by 12, we get 9 and a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
Subtracting 108 from 111 leaves us with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 12

Going ahead to step 4:
The number 12 fits into 34 2 times, leaving a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 692.0
Deduct 24 from 34 and we're left with 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 12

Moving on to step 5:
105 divided by 12 is 8 with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 6928.0
Deduct 96 from 105 and we're left with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 12

Advancing to step 6:
The number 12 fits into 95 7 times, leaving a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 69287.0
If we subtract 84 from 95, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
If we divide 110 by 12, we get 9 and a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 69287.9
Deduct 108 from 110 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
When dividing 20 by 12, we get 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 69287.91
Subtract 12 from 20 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
If we divide 80 by 12, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 69287.916
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
12 can be fit into 80 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 69287.9166
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 69287.9166, and the remainder is 8e-05.
