We're dividing 12290668 by 944 
We want to divide 12290668 by 944.

Let's proceed to step 1:
The number 944 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 944

Advancing to step 2:
When dividing 12 by 944, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 944

Moving on to step 3:
122 divided by 944 is 0 with a remainder of 122.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 122 and we're left with 122.
Fetch the next digit (9) from the dividend, attach it to 122 and continue: 1229 / 944

Advancing to step 4:
If we divide 1229 by 944, we get 1 and a remainder of 285.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 944 from 1229, we get 285.
Bring next digit (0) of the dividend behind the 285 and repeat the process: 2850 / 944

On to step 5:
2850 divided by 944 is 3 with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 2832 from 2850 leaves us with 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 944

Going ahead to step 6:
944 goes into 186 0 times with a remainder of 186.
Use 0 as the next digit of our solution. 
Result so far: 130.0
If we take 0 away from 186, we end up with 186.
Include the next digit (6) from the dividend after 186, then repeat: 1866 / 944

Moving on to step 7:
The number 944 fits into 1866 1 times, leaving a remainder of 922.
Use 1 as the next digit of our solution. 
Result so far: 1301.0
The remainder is 922 after subtracting 944 from 1866.
Bring next digit (8) of the dividend behind the 922 and repeat the process: 9228 / 944

Going ahead to step 8:
9228 divided by 944 is 9 with a remainder of 732.
The next digit of our result is 9. 
Result so far: 13019.0
Subtract 8496 from 9228 to get 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

Going ahead to step 9:
944 can be fit into 7320 7 times, resulting in a remainder of 712.
Put 7 as the next digit of the answer. 
Result so far: 13019.7
The remainder is 712 after subtracting 6608 from 7320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Advancing to step 10:
The number 944 fits into 7120 7 times, leaving a remainder of 512.
Record the quotient 7 as the next digit in the result. 
Result so far: 13019.77
The remainder is 512 after subtracting 6608 from 7120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

The final result is 13019.77 with a remainder of 0.512.
