We look at the division of 99802004 by 515 
We want to figure out the number of times 99802004 can be divided by 515.

On to step 1:
When dividing 9 by 515, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 515

Step 2:
515 goes into 99 0 times with a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Include the next digit (8) from the dividend after 99, then repeat: 998 / 515

Moving on to step 3:
The number 515 fits into 998 1 times, leaving a remainder of 483.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 483 after subtracting 515 from 998.
Include the next digit (0) from the dividend after 483, then repeat: 4830 / 515

Going ahead to step 4:
If we divide 4830 by 515, we get 9 and a remainder of 195.
Write down 9 as next digit of the result. 
Result so far: 19.0
Deduct 4635 from 4830 and we're left with 195.
Take the next digit (2) from the dividend and append it to 195, then repeat: 1952 / 515

Going ahead to step 5:
When dividing 1952 by 515, we get 3 with a remainder of 407.
The next digit of our result is 3. 
Result so far: 193.0
Subtract 1545 from 1952 to get 407.
Grab the next digit (0) from the dividend, add it to 407, then carry on: 4070 / 515

Moving on to step 6:
515 goes into 4070 7 times with a remainder of 465.
Put 7 as the next digit of the answer. 
Result so far: 1937.0
Subtracting 3605 from 4070 leaves us with 465.
Grab the next digit (0) from the dividend, add it to 465, then carry on: 4650 / 515

Advancing to step 7:
4650 divided by 515 is 9 with a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 19379.0
If we take 4635 away from 4650, we end up with 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 515

On to step 8:
The number 515 fits into 154 0 times, leaving a remainder of 154.
Write down 0 as next digit of the result. 
Result so far: 193790.0
If we subtract 0 from 154, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Advancing to step 9:
When dividing 1540 by 515, we get 2 with a remainder of 510.
The number 2 becomes the next digit in our result. 
Result so far: 193790.2
If we take 1030 away from 1540, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

On to step 10:
The number 515 fits into 5100 9 times, leaving a remainder of 465.
Use 9 as the next digit of our solution. 
Result so far: 193790.29
The remainder is 465 after subtracting 4635 from 5100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

On to step 11:
4650 divided by 515 is 9 with a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 193790.299
Subtract 4635 from 4650 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 193790.299 with a remaining 0.0015.
