Let's divide 812572 by 12
Our goal is to divide 812572 by 12.

Going ahead 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
If we subtract 0 from 8, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 12

Let's proceed to step 2:
12 goes into 81 6 times with 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 (2) from the dividend to 9 and continue with: 92 / 12

Moving on to step 3:
When dividing 92 by 12, we get 7 with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 67.0
Subtracting 84 from 92 leaves us with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 12

On to step 4:
If we divide 85 by 12, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 677.0
If we subtract 84 from 85, we get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 12

Going ahead to step 5:
12 goes into 17 1 times with a remainder of 5.
The next digit of our result is 1. 
Result so far: 6771.0
The remainder is 5 after subtracting 12 from 17.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 12

On to step 6:
The number 12 fits into 52 4 times, leaving a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 67714.0
Deduct 48 from 52 and we're left 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.

Moving on to step 7:
40 divided by 12 is 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 67714.3
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 67714.33
Subtracting 36 from 40 leaves us 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.

The final outcome is 67714.33, with a leftover of 0.004.
