We look at the division of 12615071 by 515 
We want to divide 12615071 by 515.

Step 1:
If we divide 1 by 515, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 515

Going ahead to step 2:
12 divided by 515 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 515

Advancing to step 3:
515 can be fit into 126 0 times, resulting in a remainder of 126.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 126 to get 126.
Include the next digit (1) from the dividend after 126, then repeat: 1261 / 515

Going ahead to step 4:
The number 515 fits into 1261 2 times, leaving a remainder of 231.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 231 after subtracting 1030 from 1261.
Bring next digit (5) of the dividend behind the 231 and repeat the process: 2315 / 515

Step 5:
The number 515 fits into 2315 4 times, leaving a remainder of 255.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we take 2060 away from 2315, we end up with 255.
Take the next digit (0) from the dividend and append it to 255, then repeat: 2550 / 515

Moving on to step 6:
515 can be fit into 2550 4 times, resulting in a remainder of 490.
Record the quotient 4 as the next digit in the result. 
Result so far: 244.0
Subtracting 2060 from 2550 leaves us with 490.
Grab the next digit (7) from the dividend, add it to 490, then carry on: 4907 / 515

Advancing to step 7:
When dividing 4907 by 515, we get 9 with a remainder of 272.
Put 9 as the next digit of the answer. 
Result so far: 2449.0
Subtract 4635 from 4907 to get 272.
Include the next digit (1) from the dividend after 272, then repeat: 2721 / 515

Going ahead to step 8:
When dividing 2721 by 515, we get 5 with a remainder of 146.
Use 5 as the next digit of our solution. 
Result so far: 24495.0
Deduct 2575 from 2721 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 9:
515 can be fit into 1460 2 times, resulting in a remainder of 430.
Record the quotient 2 as the next digit in the result. 
Result so far: 24495.2
If we take 1030 away from 1460, we end up with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 10:
515 can be fit into 4300 8 times, resulting in a remainder of 180.
Record the quotient 8 as the next digit in the result. 
Result so far: 24495.28
The remainder is 180 after subtracting 4120 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 11:
If we divide 1800 by 515, we get 3 and a remainder of 255.
Use 3 as the next digit of our solution. 
Result so far: 24495.283
Subtract 1545 from 1800 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 12:
2550 divided by 515 is 4 with a remainder of 490.
Use 4 as the next digit of our solution. 
Result so far: 24495.2834
If we subtract 2060 from 2550, we get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 13:
515 can be fit into 4900 9 times, resulting in a remainder of 265.
Use 9 as the next digit of our solution. 
Result so far: 24495.28349
Subtract 4635 from 4900 to get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

On to step 14:
515 can be fit into 2650 5 times, resulting in a remainder of 75.
The next digit of our result is 5. 
Result so far: 24495.283495
Subtracting 2575 from 2650 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 15:
The number 515 fits into 750 1 times, leaving a remainder of 235.
Record the quotient 1 as the next digit in the result. 
Result so far: 24495.2834951
The remainder is 235 after subtracting 515 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Let's proceed to step 16:
2350 divided by 515 is 4 with a remainder of 290.
Write down 4 as next digit of the result. 
Result so far: 24495.28349514
Subtract 2060 from 2350 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

In conclusion, the division gives 24495.28349514 with a balance of 2.9e-07.
