We look at the division of 503317 by 99 
Our goal is to divide 503317 by 99.

Going ahead to step 1:
The number 99 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 99

Moving on to step 2:
99 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Bring next digit (3) of the dividend behind the 50 and repeat the process: 503 / 99

Step 3:
If we divide 503 by 99, we get 5 and a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 495 from 503 leaves us with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 99

Step 4:
99 goes into 83 0 times with a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Subtract 0 from 83 to get 83.
Include the next digit (1) from the dividend after 83, then repeat: 831 / 99

Advancing to step 5:
If we divide 831 by 99, we get 8 and a remainder of 39.
Write down 8 as next digit of the result. 
Result so far: 508.0
If we subtract 792 from 831, we get 39.
Grab the next digit (7) from the dividend, add it to 39, then carry on: 397 / 99

Moving on to step 6:
99 goes into 397 4 times with a remainder of 1.
The next digit of our result is 4. 
Result so far: 5084.0
Subtracting 396 from 397 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
99 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 5084.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
If we divide 100 by 99, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 5084.01
The remainder is 1 after subtracting 99 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
99 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 5084.01
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
The number 99 fits into 100 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 5084.0101
Subtracting 99 from 100 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 11:
99 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 5084.0101
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
99 can be fit into 100 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 5084.010101
If we subtract 99 from 100, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 13:
99 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 5084.010101
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
If we divide 100 by 99, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 5084.01010101
The remainder is 1 after subtracting 99 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 5084.01010101 and a remainder of 1e-09.
