Let's divide 508990 by 99
We're looking to find how many times 99 goes into 508990.

Going ahead to step 1:
99 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
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

Let's proceed to step 2:
50 divided by 99 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Bring next digit (8) of the dividend behind the 50 and repeat the process: 508 / 99

Step 3:
If we divide 508 by 99, we get 5 and a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 495 from 508 and we're left with 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 99

Moving on to step 4:
The number 99 fits into 139 1 times, leaving a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
Subtract 99 from 139 to get 40.
Take the next digit (9) from the dividend and append it to 40, then repeat: 409 / 99

On to step 5:
The number 99 fits into 409 4 times, leaving a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 514.0
Subtracting 396 from 409 leaves us with 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 99

Going ahead to step 6:
99 can be fit into 130 1 times, resulting in a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 5141.0
The remainder is 31 after subtracting 99 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 7:
310 divided by 99 is 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 5141.3
If we take 297 away from 310, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 8:
99 goes into 130 1 times with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 5141.31
If we subtract 99 from 130, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 9:
When dividing 310 by 99, we get 3 with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 5141.313
If we subtract 297 from 310, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 10:
If we divide 130 by 99, we get 1 and a remainder of 31.
The next digit of our result is 1. 
Result so far: 5141.3131
The remainder is 31 after subtracting 99 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 11:
99 can be fit into 310 3 times, resulting in a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 5141.31313
If we take 297 away from 310, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 12:
The number 99 fits into 130 1 times, leaving a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 5141.313131
If we subtract 99 from 130, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 13:
When dividing 310 by 99, we get 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 5141.3131313
Deduct 297 from 310 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 14:
The number 99 fits into 130 1 times, leaving a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 5141.31313131
Subtracting 99 from 130 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final result is 5141.31313131 with a remainder of 3.1e-08.
