Let's divide 12745770 by 921
We want to divide 12745770 by 921.

On to step 1:
1 divided by 921 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 921

Going ahead to step 2:
The number 921 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 921

Let's proceed to step 3:
921 goes into 127 0 times with a remainder of 127.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 127 and we're left with 127.
Grab the next digit (4) from the dividend, add it to 127, then carry on: 1274 / 921

Moving on to step 4:
921 goes into 1274 1 times with a remainder of 353.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 921 away from 1274, we end up with 353.
Grab the next digit (5) from the dividend, add it to 353, then carry on: 3535 / 921

Step 5:
The number 921 fits into 3535 3 times, leaving a remainder of 772.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 2763 from 3535, we get 772.
Fetch the next digit (7) from the dividend, attach it to 772 and continue: 7727 / 921

Let's proceed to step 6:
7727 divided by 921 is 8 with a remainder of 359.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
Subtract 7368 from 7727 to get 359.
Append the next digit (7) from the dividend to 359 and continue with: 3597 / 921

Let's proceed to step 7:
The number 921 fits into 3597 3 times, leaving a remainder of 834.
Record the quotient 3 as the next digit in the result. 
Result so far: 1383.0
Deduct 2763 from 3597 and we're left with 834.
Append the next digit (0) from the dividend to 834 and continue with: 8340 / 921

Let's proceed to step 8:
When dividing 8340 by 921, we get 9 with a remainder of 51.
The number 9 becomes the next digit in our result. 
Result so far: 13839.0
Subtract 8289 from 8340 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 9:
921 goes into 510 0 times with a remainder of 510.
The next digit of our result is 0. 
Result so far: 13839.0
Subtract 0 from 510 to get 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Step 10:
5100 divided by 921 is 5 with a remainder of 495.
Write down 5 as next digit of the result. 
Result so far: 13839.05
Deduct 4605 from 5100 and we're left with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

On to step 11:
4950 divided by 921 is 5 with a remainder of 345.
The number 5 becomes the next digit in our result. 
Result so far: 13839.055
If we subtract 4605 from 4950, we get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Our division results in 13839.055 with a remaining 0.0345.
