83606884 ÷ 12 
We want to divide 83606884 by 12.

On to step 1:
If we divide 8 by 12, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 12

Step 2:
When dividing 83 by 12, we get 6 with a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 72 away from 83, we end up with 11.
Append the next digit (6) from the dividend to 11 and continue with: 116 / 12

Step 3:
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: 69.0
Deduct 108 from 116 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 12

Advancing to step 4:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 696.0
Subtracting 72 from 80 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 12

Let's proceed to step 5:
12 can be fit into 86 7 times, resulting in a remainder of 2.
The next digit of our result is 7. 
Result so far: 6967.0
Subtracting 84 from 86 leaves us with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 12

On to step 6:
12 goes into 28 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 69672.0
If we take 24 away from 28, we end up with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 12

Moving on to step 7:
The number 12 fits into 48 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 696724.0
Subtracting 48 from 48 leaves us with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 12

On to step 8:
4 divided by 12 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 6967240.0
Deduct 0 from 4 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.

Advancing to step 9:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 6967240.3
If we take 36 away from 40, we end up 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 10:
When dividing 40 by 12, we get 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 6967240.33
If we subtract 36 from 40, we get 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 quotient of the division is 6967240.33, and the remainder is 0.004.
