78069536 divided by 12 
We want to figure out the number of times 78069536 can be divided by 12.

Step 1:
When dividing 7 by 12, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 12

Going ahead to step 2:
The number 12 fits into 78 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 6 after subtracting 72 from 78.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 12

On to step 3:
When dividing 60 by 12, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
Subtract 60 from 60 to get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 12

Going ahead to step 4:
6 divided by 12 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 650.0
If we take 0 away from 6, we end up with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 12

Step 5:
12 can be fit into 69 5 times, resulting in a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 6505.0
Subtract 60 from 69 to get 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 12

Step 6:
12 can be fit into 95 7 times, resulting in a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 65057.0
The remainder is 11 after subtracting 84 from 95.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 12

Let's proceed to step 7:
113 divided by 12 is 9 with a remainder of 5.
The next digit of our result is 9. 
Result so far: 650579.0
If we subtract 108 from 113, we get 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 12

Going ahead to step 8:
56 divided by 12 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 6505794.0
If we subtract 48 from 56, we 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.

Let's proceed to step 9:
12 can be fit into 80 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 6505794.6
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.

Step 10:
12 goes into 80 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 6505794.66
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 6505794.66, and the remainder is 0.008.
