We look at the division of 126107 by 12 
We want to divide 126107 by 12.

Advancing to step 1:
If we divide 1 by 12, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 12

Let's proceed to step 2:
The number 12 fits into 12 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 12 away from 12, we end up with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 12

Let's proceed to step 3:
12 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 12

On to step 4:
12 goes into 61 5 times with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
The remainder is 1 after subtracting 60 from 61.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 12

Going ahead to step 5:
12 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 1050.0
If we take 0 away from 10, we end up with 10.
Fetch the next digit (7) from the dividend, attach it to 10 and continue: 107 / 12

Step 6:
12 goes into 107 8 times with a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 10508.0
If we subtract 96 from 107, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
The number 12 fits into 110 9 times, leaving a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 10508.9
If we subtract 108 from 110, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
20 divided by 12 is 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 10508.91
If we subtract 12 from 20, 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.

Moving on to step 9:
If we divide 80 by 12, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 10508.916
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.

Let's proceed to step 10:
If we divide 80 by 12, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 10508.9166
If we subtract 72 from 80, 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.

After the division, we end up with 10508.9166 and a remainder of 8e-05.
