We look at the division of 81524607 by 12 
We want to figure out the number of times 81524607 can be divided 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
If we subtract 0 from 8, we get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 12

Let's proceed to step 2:
The number 12 fits into 81 6 times, leaving a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 72 from 81 and we're left with 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 12

Going ahead to step 3:
When dividing 95 by 12, we get 7 with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 67.0
If we subtract 84 from 95, we get 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 12

On to step 4:
If we divide 112 by 12, we get 9 and a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 679.0
The remainder is 4 after subtracting 108 from 112.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 12

Going ahead to step 5:
The number 12 fits into 44 3 times, leaving a remainder of 8.
The next digit of our result is 3. 
Result so far: 6793.0
Subtract 36 from 44 to get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 12

Let's proceed to step 6:
12 goes into 86 7 times with a remainder of 2.
The next digit of our result is 7. 
Result so far: 67937.0
The remainder is 2 after subtracting 84 from 86.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 12

Moving on to step 7:
The number 12 fits into 20 1 times, leaving a remainder of 8.
The next digit of our result is 1. 
Result so far: 679371.0
Subtracting 12 from 20 leaves us with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 12

Advancing to step 8:
12 can be fit into 87 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 6793717.0
The remainder is 3 after subtracting 84 from 87.
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 9:
The number 12 fits into 30 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 6793717.2
Deduct 24 from 30 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 6793717.25
If we take 60 away from 60, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
12 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6793717.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
0 divided by 12 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6793717.25
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 6793717.25, and the remainder is 0.0.
