508809 divided by 99 
We're looking to find how many times 99 goes into 508809.

On to step 1:
5 divided by 99 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 99

On to step 2:
The number 99 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Take the next digit (8) from the dividend and append it to 50, then repeat: 508 / 99

Advancing to step 3:
508 divided by 99 is 5 with a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 495 from 508 to get 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 99

Let's proceed to step 4:
99 goes into 138 1 times with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
The remainder is 39 after subtracting 99 from 138.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 99

Going ahead to step 5:
390 divided by 99 is 3 with a remainder of 93.
Record the quotient 3 as the next digit in the result. 
Result so far: 513.0
If we subtract 297 from 390, we get 93.
Grab the next digit (9) from the dividend, add it to 93, then carry on: 939 / 99

Going ahead to step 6:
939 divided by 99 is 9 with a remainder of 48.
Write down 9 as next digit of the result. 
Result so far: 5139.0
Deduct 891 from 939 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 7:
480 divided by 99 is 4 with a remainder of 84.
Use 4 as the next digit of our solution. 
Result so far: 5139.4
The remainder is 84 after subtracting 396 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 8:
When dividing 840 by 99, we get 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 5139.48
Subtracting 792 from 840 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 9:
99 can be fit into 480 4 times, resulting in a remainder of 84.
The next digit of our result is 4. 
Result so far: 5139.484
The remainder is 84 after subtracting 396 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 10:
99 goes into 840 8 times with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 5139.4848
Subtract 792 from 840 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
If we divide 480 by 99, we get 4 and a remainder of 84.
Record the quotient 4 as the next digit in the result. 
Result so far: 5139.48484
If we take 396 away from 480, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 12:
99 goes into 840 8 times with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 5139.484848
If we subtract 792 from 840, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
If we divide 480 by 99, we get 4 and a remainder of 84.
Record the quotient 4 as the next digit in the result. 
Result so far: 5139.4848484
If we take 396 away from 480, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 14:
If we divide 840 by 99, we get 8 and a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 5139.48484848
Deduct 792 from 840 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 5139.48484848 with a remainder of 4.8e-08.
