We divide 811936 by 12
We want to divide 811936 by 12.

On to step 1:
If we divide 8 by 12, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 12

Step 2:
The number 12 fits into 81 6 times, leaving a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 72 from 81 leaves us with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 12

Going ahead to step 3:
12 goes into 91 7 times with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 67.0
If we subtract 84 from 91, we get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 12

Let's proceed to step 4:
12 can be fit into 79 6 times, resulting in a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 676.0
Subtracting 72 from 79 leaves us with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 12

On to step 5:
12 can be fit into 73 6 times, resulting in a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 6766.0
Deduct 72 from 73 and we're left with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 12

Advancing to step 6:
12 goes into 16 1 times with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 67661.0
Subtract 12 from 16 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 67661.3
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
When dividing 40 by 12, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 67661.33
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 67661.33, and the remainder is 0.004.
