108643 divided by 12 
We're looking to find how many times 12 goes into 108643.

Advancing to step 1:
12 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 12

Step 2:
12 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 12

Going ahead to step 3:
The number 12 fits into 108 9 times, leaving a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 108 from 108 and we're left with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 12

Step 4:
When dividing 6 by 12, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 90.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 12

Advancing to step 5:
The number 12 fits into 64 5 times, leaving a remainder of 4.
The next digit of our result is 5. 
Result so far: 905.0
Subtracting 60 from 64 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 12

On to step 6:
43 divided by 12 is 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 9053.0
If we take 36 away from 43, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
If we divide 70 by 12, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 9053.5
The remainder is 10 after subtracting 60 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
12 goes into 100 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 9053.58
Subtract 96 from 100 to 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.

On to step 9:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 9053.583
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:
If we divide 40 by 12, we get 3 and a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 9053.5833
Subtract 36 from 40 to 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 9053.5833, and the remainder is 4e-05.
