109603 divided by 12 
We want to divide 109603 by 12.

Moving on to step 1:
When dividing 1 by 12, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 12

Going ahead to step 2:
10 divided by 12 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 12

Step 3:
109 divided by 12 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 108 from 109 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 12

Moving on to step 4:
The number 12 fits into 16 1 times, leaving a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
Subtracting 12 from 16 leaves us with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 12

Step 5:
40 divided by 12 is 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 913.0
If we take 36 away from 40, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 12

Moving on to step 6:
12 goes into 43 3 times with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 9133.0
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.

Moving on to step 7:
The number 12 fits into 70 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 9133.5
If we subtract 60 from 70, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
When dividing 100 by 12, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 9133.58
Deduct 96 from 100 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:
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: 9133.583
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:
40 divided by 12 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 9133.5833
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.

The quotient of the division is 9133.5833, and the remainder is 4e-05.
