515080 divided by 99 
We want to figure out the number of times 515080 can be divided by 99.

Going ahead to step 1:
99 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 99

Advancing to step 2:
If we divide 51 by 99, we get 0 and a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 99

On to step 3:
99 goes into 515 5 times with a remainder of 20.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 495 from 515 and we're left with 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 99

Moving on to step 4:
The number 99 fits into 200 2 times, leaving a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 52.0
The remainder is 2 after subtracting 198 from 200.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 99

On to step 5:
99 can be fit into 28 0 times, resulting in a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 520.0
If we take 0 away from 28, we end up with 28.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 99

Let's proceed to step 6:
280 divided by 99 is 2 with a remainder of 82.
The number 2 becomes the next digit in our result. 
Result so far: 5202.0
Deduct 198 from 280 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 7:
If we divide 820 by 99, we get 8 and a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 5202.8
Subtract 792 from 820 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 8:
If we divide 280 by 99, we get 2 and a remainder of 82.
Write down 2 as next digit of the result. 
Result so far: 5202.82
Subtracting 198 from 280 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 9:
The number 99 fits into 820 8 times, leaving a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 5202.828
Deduct 792 from 820 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
When dividing 280 by 99, we get 2 with a remainder of 82.
The next digit of our result is 2. 
Result so far: 5202.8282
If we take 198 away from 280, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 11:
The number 99 fits into 820 8 times, leaving a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 5202.82828
Deduct 792 from 820 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
When dividing 280 by 99, we get 2 with a remainder of 82.
The number 2 becomes the next digit in our result. 
Result so far: 5202.828282
If we take 198 away from 280, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 13:
99 goes into 820 8 times with a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 5202.8282828
Subtract 792 from 820 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 14:
If we divide 280 by 99, we get 2 and a remainder of 82.
Put 2 as the next digit of the answer. 
Result so far: 5202.82828282
Deduct 198 from 280 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Our division results in 5202.82828282 with a remaining 8.2e-08.
