We divide 810810 by 12
Let's see how many times 12 fits into 810810.

Advancing to step 1:
12 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 12

Going ahead to step 2:
When dividing 81 by 12, we get 6 with a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 72 away from 81, we end up with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 12

Step 3:
When dividing 90 by 12, we get 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
If we subtract 84 from 90, we get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 12

Going ahead to step 4:
12 goes into 68 5 times with a remainder of 8.
The next digit of our result is 5. 
Result so far: 675.0
If we subtract 60 from 68, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 12

Going ahead to step 5:
81 divided by 12 is 6 with a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 6756.0
Deduct 72 from 81 and we're left with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 12

Step 6:
If we divide 90 by 12, we get 7 and a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 67567.0
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
If we divide 60 by 12, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 67567.5
Deduct 60 from 60 and we're left 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.

Step 8:
If we divide 0 by 12, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 67567.5
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 9:
When dividing 0 by 12, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 67567.5
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 final result is 67567.5 with a remainder of 0.0.
