We're dividing 263911 by 12 
We want to divide 263911 by 12.

Moving on to step 1:
2 divided by 12 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 12

Going ahead to step 2:
The number 12 fits into 26 2 times, leaving a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 24 from 26, we get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 12

Going ahead to step 3:
If we divide 23 by 12, we get 1 and a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 21.0
The remainder is 11 after subtracting 12 from 23.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 12

On to step 4:
12 can be fit into 119 9 times, resulting in a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 219.0
If we subtract 108 from 119, we get 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 12

Going ahead to step 5:
12 goes into 111 9 times with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 2199.0
Subtracting 108 from 111 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 12

Step 6:
When dividing 31 by 12, we get 2 with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 21992.0
Subtracting 24 from 31 leaves us 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.
Write down 5 as next digit of the result. 
Result so far: 21992.5
Subtracting 60 from 70 leaves us with 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.
The number 8 becomes the next digit in our result. 
Result so far: 21992.58
The remainder is 4 after subtracting 96 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
If we divide 40 by 12, we get 3 and a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 21992.583
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead 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: 21992.5833
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 final result is 21992.5833 with a remainder of 4e-05.
