We look at the division of 12965597 by 280 
We want to divide 12965597 by 280.

Moving on to step 1:
If we divide 1 by 280, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 280

Going ahead to step 2:
280 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 280

Advancing to step 3:
When dividing 129 by 280, we get 0 with a remainder of 129.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 129 to get 129.
Append the next digit (6) from the dividend to 129 and continue with: 1296 / 280

Going ahead to step 4:
The number 280 fits into 1296 4 times, leaving a remainder of 176.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 1120 from 1296 to get 176.
Append the next digit (5) from the dividend to 176 and continue with: 1765 / 280

Step 5:
The number 280 fits into 1765 6 times, leaving a remainder of 85.
Use 6 as the next digit of our solution. 
Result so far: 46.0
Subtract 1680 from 1765 to get 85.
Include the next digit (5) from the dividend after 85, then repeat: 855 / 280

Moving on to step 6:
280 goes into 855 3 times with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 463.0
If we take 840 away from 855, we end up with 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 280

Advancing to step 7:
280 goes into 159 0 times with a remainder of 159.
Record the quotient 0 as the next digit in the result. 
Result so far: 4630.0
The remainder is 159 after subtracting 0 from 159.
Fetch the next digit (7) from the dividend, attach it to 159 and continue: 1597 / 280

Step 8:
If we divide 1597 by 280, we get 5 and a remainder of 197.
The number 5 becomes the next digit in our result. 
Result so far: 46305.0
If we take 1400 away from 1597, we end up with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Going ahead to step 9:
280 can be fit into 1970 7 times, resulting in a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 46305.7
Subtracting 1960 from 1970 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.

Step 10:
The number 280 fits into 100 0 times, leaving a remainder of 100.
The next digit of our result is 0. 
Result so far: 46305.7
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 11:
280 can be fit into 1000 3 times, resulting in a remainder of 160.
Write down 3 as next digit of the result. 
Result so far: 46305.703
Subtract 840 from 1000 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 12:
1600 divided by 280 is 5 with a remainder of 200.
The number 5 becomes the next digit in our result. 
Result so far: 46305.7035
If we take 1400 away from 1600, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 13:
280 can be fit into 2000 7 times, resulting in a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 46305.70357
The remainder is 40 after subtracting 1960 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
280 can be fit into 400 1 times, resulting in a remainder of 120.
Put 1 as the next digit of the answer. 
Result so far: 46305.703571
Deduct 280 from 400 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 15:
280 can be fit into 1200 4 times, resulting in a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 46305.7035714
The remainder is 80 after subtracting 1120 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 16:
When dividing 800 by 280, we get 2 with a remainder of 240.
The number 2 becomes the next digit in our result. 
Result so far: 46305.70357142
If we take 560 away from 800, we end up 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.

After the division, we end up with 46305.70357142 and a remainder of 2.4e-07.
