12091077 divided by 515 
We want to divide 12091077 by 515.

Advancing to step 1:
1 divided by 515 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 515

Going ahead to step 2:
515 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 515

On to step 3:
When dividing 120 by 515, we get 0 with a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 120 to get 120.
Include the next digit (9) from the dividend after 120, then repeat: 1209 / 515

Step 4:
The number 515 fits into 1209 2 times, leaving a remainder of 179.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 179 after subtracting 1030 from 1209.
Take the next digit (1) from the dividend and append it to 179, then repeat: 1791 / 515

Let's proceed to step 5:
If we divide 1791 by 515, we get 3 and a remainder of 246.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Deduct 1545 from 1791 and we're left with 246.
Grab the next digit (0) from the dividend, add it to 246, then carry on: 2460 / 515

Moving on to step 6:
515 goes into 2460 4 times with a remainder of 400.
Put 4 as the next digit of the answer. 
Result so far: 234.0
Deduct 2060 from 2460 and we're left with 400.
Grab the next digit (7) from the dividend, add it to 400, then carry on: 4007 / 515

Advancing to step 7:
515 can be fit into 4007 7 times, resulting in a remainder of 402.
The next digit of our result is 7. 
Result so far: 2347.0
If we subtract 3605 from 4007, we get 402.
Take the next digit (7) from the dividend and append it to 402, then repeat: 4027 / 515

Moving on to step 8:
4027 divided by 515 is 7 with a remainder of 422.
Write down 7 as next digit of the result. 
Result so far: 23477.0
Subtracting 3605 from 4027 leaves us with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

On to step 9:
515 can be fit into 4220 8 times, resulting in a remainder of 100.
Use 8 as the next digit of our solution. 
Result so far: 23477.8
If we subtract 4120 from 4220, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 10:
If we divide 1000 by 515, we get 1 and a remainder of 485.
Use 1 as the next digit of our solution. 
Result so far: 23477.81
Deduct 515 from 1000 and we're left with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Advancing to step 11:
The number 515 fits into 4850 9 times, leaving a remainder of 215.
Write down 9 as next digit of the result. 
Result so far: 23477.819
If we subtract 4635 from 4850, we get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

On to step 12:
2150 divided by 515 is 4 with a remainder of 90.
The next digit of our result is 4. 
Result so far: 23477.8194
Deduct 2060 from 2150 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 13:
900 divided by 515 is 1 with a remainder of 385.
Write down 1 as next digit of the result. 
Result so far: 23477.81941
Subtracting 515 from 900 leaves us with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Step 14:
515 can be fit into 3850 7 times, resulting in a remainder of 245.
The next digit of our result is 7. 
Result so far: 23477.819417
If we take 3605 away from 3850, we end up with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Step 15:
When dividing 2450 by 515, we get 4 with a remainder of 390.
Use 4 as the next digit of our solution. 
Result so far: 23477.8194174
Subtracting 2060 from 2450 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 16:
3900 divided by 515 is 7 with a remainder of 295.
The number 7 becomes the next digit in our result. 
Result so far: 23477.81941747
Subtracting 3605 from 3900 leaves us with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

In conclusion, the division gives 23477.81941747 with a balance of 2.95e-07.
