863636 divided by 12 
We want to figure out the number of times 863636 can be divided by 12.

Let's proceed to step 1:
When dividing 8 by 12, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 12

On to step 2:
86 divided by 12 is 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 2 after subtracting 84 from 86.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 12

Moving on to step 3:
The number 12 fits into 23 1 times, leaving a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
If we subtract 12 from 23, we get 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 12

Advancing to step 4:
When dividing 116 by 12, we get 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 719.0
The remainder is 8 after subtracting 108 from 116.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 12

Step 5:
When dividing 83 by 12, we get 6 with a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 7196.0
The remainder is 11 after subtracting 72 from 83.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 12

Moving on to step 6:
The number 12 fits into 116 9 times, leaving a remainder of 8.
The next digit of our result is 9. 
Result so far: 71969.0
The remainder is 8 after subtracting 108 from 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 71969.6
Subtract 72 from 80 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 8:
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: 71969.66
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.

Our division results in 71969.66 with a remaining 0.008.
