12650800 divided by 515 
We want to divide 12650800 by 515.

Step 1:
When dividing 1 by 515, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 515

Let's proceed to step 2:
If we divide 12 by 515, we get 0 and a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 515

Advancing to step 3:
126 divided by 515 is 0 with a remainder of 126.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 126 and we're left with 126.
Bring next digit (5) of the dividend behind the 126 and repeat the process: 1265 / 515

Going ahead to step 4:
1265 divided by 515 is 2 with a remainder of 235.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1030 from 1265 leaves us with 235.
Take the next digit (0) from the dividend and append it to 235, then repeat: 2350 / 515

Advancing to step 5:
515 can be fit into 2350 4 times, resulting in a remainder of 290.
Write down 4 as next digit of the result. 
Result so far: 24.0
The remainder is 290 after subtracting 2060 from 2350.
Take the next digit (8) from the dividend and append it to 290, then repeat: 2908 / 515

Let's proceed to step 6:
2908 divided by 515 is 5 with a remainder of 333.
Write down 5 as next digit of the result. 
Result so far: 245.0
The remainder is 333 after subtracting 2575 from 2908.
Append the next digit (0) from the dividend to 333 and continue with: 3330 / 515

Moving on to step 7:
The number 515 fits into 3330 6 times, leaving a remainder of 240.
The next digit of our result is 6. 
Result so far: 2456.0
Subtracting 3090 from 3330 leaves us with 240.
Fetch the next digit (0) from the dividend, attach it to 240 and continue: 2400 / 515

Step 8:
515 goes into 2400 4 times with a remainder of 340.
Write down 4 as next digit of the result. 
Result so far: 24564.0
If we subtract 2060 from 2400, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 9:
3400 divided by 515 is 6 with a remainder of 310.
The number 6 becomes the next digit in our result. 
Result so far: 24564.6
Deduct 3090 from 3400 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 10:
3100 divided by 515 is 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 24564.66
The remainder is 10 after subtracting 3090 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 24564.66 with a remaining 0.01.
