We look at the division of 99608711 by 503 
We want to figure out the number of times 99608711 can be divided by 503.

Step 1:
The number 503 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 503

Going ahead to step 2:
When dividing 99 by 503, we get 0 with a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Include the next digit (6) from the dividend after 99, then repeat: 996 / 503

Advancing to step 3:
503 goes into 996 1 times with a remainder of 493.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 493 after subtracting 503 from 996.
Fetch the next digit (0) from the dividend, attach it to 493 and continue: 4930 / 503

On to step 4:
If we divide 4930 by 503, we get 9 and a remainder of 403.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtract 4527 from 4930 to get 403.
Take the next digit (8) from the dividend and append it to 403, then repeat: 4038 / 503

Moving on to step 5:
4038 divided by 503 is 8 with a remainder of 14.
The next digit of our result is 8. 
Result so far: 198.0
If we subtract 4024 from 4038, we get 14.
Take the next digit (7) from the dividend and append it to 14, then repeat: 147 / 503

Moving on to step 6:
503 can be fit into 147 0 times, resulting in a remainder of 147.
The next digit of our result is 0. 
Result so far: 1980.0
Subtracting 0 from 147 leaves us with 147.
Append the next digit (1) from the dividend to 147 and continue with: 1471 / 503

Going ahead to step 7:
503 goes into 1471 2 times with a remainder of 465.
Put 2 as the next digit of the answer. 
Result so far: 19802.0
If we subtract 1006 from 1471, we get 465.
Append the next digit (1) from the dividend to 465 and continue with: 4651 / 503

On to step 8:
4651 divided by 503 is 9 with a remainder of 124.
Record the quotient 9 as the next digit in the result. 
Result so far: 198029.0
If we subtract 4527 from 4651, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 9:
If we divide 1240 by 503, we get 2 and a remainder of 234.
The number 2 becomes the next digit in our result. 
Result so far: 198029.2
If we subtract 1006 from 1240, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Moving on to step 10:
503 can be fit into 2340 4 times, resulting in a remainder of 328.
The number 4 becomes the next digit in our result. 
Result so far: 198029.24
Deduct 2012 from 2340 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Going ahead to step 11:
3280 divided by 503 is 6 with a remainder of 262.
The number 6 becomes the next digit in our result. 
Result so far: 198029.246
If we take 3018 away from 3280, we end up with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

On to step 12:
The number 503 fits into 2620 5 times, leaving a remainder of 105.
Record the quotient 5 as the next digit in the result. 
Result so far: 198029.2465
If we subtract 2515 from 2620, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 13:
The number 503 fits into 1050 2 times, leaving a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 198029.24652
The remainder is 44 after subtracting 1006 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 14:
503 goes into 440 0 times with a remainder of 440.
Put 0 as the next digit of the answer. 
Result so far: 198029.24652
If we take 0 away from 440, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 15:
The number 503 fits into 4400 8 times, leaving a remainder of 376.
The number 8 becomes the next digit in our result. 
Result so far: 198029.2465208
The remainder is 376 after subtracting 4024 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

On to step 16:
When dividing 3760 by 503, we get 7 with a remainder of 239.
The next digit of our result is 7. 
Result so far: 198029.24652087
If we subtract 3521 from 3760, we get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

The final outcome is 198029.24652087, with a leftover of 2.39e-07.
