20383072 ÷ 515 
We're looking to find how many times 515 goes into 20383072.

Going ahead to step 1:
If we divide 2 by 515, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 515

Moving on to step 2:
515 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 515

Let's proceed to step 3:
The number 515 fits into 203 0 times, leaving a remainder of 203.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 203 after subtracting 0 from 203.
Append the next digit (8) from the dividend to 203 and continue with: 2038 / 515

Let's proceed to step 4:
The number 515 fits into 2038 3 times, leaving a remainder of 493.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 1545 from 2038 to get 493.
Take the next digit (3) from the dividend and append it to 493, then repeat: 4933 / 515

On to step 5:
515 goes into 4933 9 times with a remainder of 298.
Put 9 as the next digit of the answer. 
Result so far: 39.0
The remainder is 298 after subtracting 4635 from 4933.
Grab the next digit (0) from the dividend, add it to 298, then carry on: 2980 / 515

Moving on to step 6:
If we divide 2980 by 515, we get 5 and a remainder of 405.
Put 5 as the next digit of the answer. 
Result so far: 395.0
Deduct 2575 from 2980 and we're left with 405.
Fetch the next digit (7) from the dividend, attach it to 405 and continue: 4057 / 515

Moving on to step 7:
If we divide 4057 by 515, we get 7 and a remainder of 452.
The number 7 becomes the next digit in our result. 
Result so far: 3957.0
Subtract 3605 from 4057 to get 452.
Include the next digit (2) from the dividend after 452, then repeat: 4522 / 515

Going ahead to step 8:
515 can be fit into 4522 8 times, resulting in a remainder of 402.
The number 8 becomes the next digit in our result. 
Result so far: 39578.0
If we take 4120 away from 4522, we end up with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Going ahead to step 9:
4020 divided by 515 is 7 with a remainder of 415.
The next digit of our result is 7. 
Result so far: 39578.7
If we take 3605 away from 4020, we end up with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Moving on to step 10:
If we divide 4150 by 515, we get 8 and a remainder of 30.
The next digit of our result is 8. 
Result so far: 39578.78
Deduct 4120 from 4150 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
515 can be fit into 300 0 times, resulting in a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 39578.78
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 12:
When dividing 3000 by 515, we get 5 with a remainder of 425.
The next digit of our result is 5. 
Result so far: 39578.7805
Subtract 2575 from 3000 to get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Advancing to step 13:
The number 515 fits into 4250 8 times, leaving a remainder of 130.
Write down 8 as next digit of the result. 
Result so far: 39578.78058
The remainder is 130 after subtracting 4120 from 4250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 14:
The number 515 fits into 1300 2 times, leaving a remainder of 270.
The number 2 becomes the next digit in our result. 
Result so far: 39578.780582
If we subtract 1030 from 1300, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 15:
2700 divided by 515 is 5 with a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 39578.7805825
Subtract 2575 from 2700 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 16:
515 can be fit into 1250 2 times, resulting in a remainder of 220.
The number 2 becomes the next digit in our result. 
Result so far: 39578.78058252
If we subtract 1030 from 1250, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

In conclusion, the division gives 39578.78058252 with a balance of 2.2e-07.
