12815097 ÷ 920 
We're looking to find how many times 920 goes into 12815097.

Advancing to step 1:
If we divide 1 by 920, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 920

Going ahead to step 2:
When dividing 12 by 920, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 920

Moving on to step 3:
920 can be fit into 128 0 times, resulting in a remainder of 128.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 128, we get 128.
Bring next digit (1) of the dividend behind the 128 and repeat the process: 1281 / 920

Moving on to step 4:
The number 920 fits into 1281 1 times, leaving a remainder of 361.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 920 from 1281 leaves us with 361.
Fetch the next digit (5) from the dividend, attach it to 361 and continue: 3615 / 920

Step 5:
920 can be fit into 3615 3 times, resulting in a remainder of 855.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 2760 from 3615 leaves us with 855.
Take the next digit (0) from the dividend and append it to 855, then repeat: 8550 / 920

On to step 6:
920 can be fit into 8550 9 times, resulting in a remainder of 270.
Record the quotient 9 as the next digit in the result. 
Result so far: 139.0
If we take 8280 away from 8550, we end up with 270.
Include the next digit (9) from the dividend after 270, then repeat: 2709 / 920

Step 7:
If we divide 2709 by 920, we get 2 and a remainder of 869.
The number 2 becomes the next digit in our result. 
Result so far: 1392.0
The remainder is 869 after subtracting 1840 from 2709.
Append the next digit (7) from the dividend to 869 and continue with: 8697 / 920

Step 8:
If we divide 8697 by 920, we get 9 and a remainder of 417.
The number 9 becomes the next digit in our result. 
Result so far: 13929.0
Deduct 8280 from 8697 and we're left with 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

On to step 9:
920 goes into 4170 4 times with a remainder of 490.
Use 4 as the next digit of our solution. 
Result so far: 13929.4
The remainder is 490 after subtracting 3680 from 4170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Step 10:
When dividing 4900 by 920, we get 5 with a remainder of 300.
Record the quotient 5 as the next digit in the result. 
Result so far: 13929.45
The remainder is 300 after subtracting 4600 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 11:
When dividing 3000 by 920, we get 3 with a remainder of 240.
Write down 3 as next digit of the result. 
Result so far: 13929.453
Subtracting 2760 from 3000 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 12:
2400 divided by 920 is 2 with a remainder of 560.
The number 2 becomes the next digit in our result. 
Result so far: 13929.4532
Subtracting 1840 from 2400 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 13:
920 can be fit into 5600 6 times, resulting in a remainder of 80.
Record the quotient 6 as the next digit in the result. 
Result so far: 13929.45326
The remainder is 80 after subtracting 5520 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 14:
The number 920 fits into 800 0 times, leaving a remainder of 800.
Write down 0 as next digit of the result. 
Result so far: 13929.45326
Deduct 0 from 800 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Going ahead to step 15:
The number 920 fits into 8000 8 times, leaving a remainder of 640.
The number 8 becomes the next digit in our result. 
Result so far: 13929.4532608
Subtract 7360 from 8000 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 16:
The number 920 fits into 6400 6 times, leaving a remainder of 880.
The number 6 becomes the next digit in our result. 
Result so far: 13929.45326086
If we take 5520 away from 6400, we end up with 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8800, and continue the process.

After the division, we end up with 13929.45326086 and a remainder of 8.8e-07.
