99904880 divided by 503 
Let's see how many times 503 fits into 99904880.

Going ahead to step 1:
When dividing 9 by 503, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 503

Advancing to step 2:
503 goes into 99 0 times with a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Include the next digit (9) from the dividend after 99, then repeat: 999 / 503

Going ahead to step 3:
When dividing 999 by 503, we get 1 with a remainder of 496.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 503 from 999 to get 496.
Bring next digit (0) of the dividend behind the 496 and repeat the process: 4960 / 503

Advancing to step 4:
The number 503 fits into 4960 9 times, leaving a remainder of 433.
The next digit of our result is 9. 
Result so far: 19.0
Subtract 4527 from 4960 to get 433.
Bring next digit (4) of the dividend behind the 433 and repeat the process: 4334 / 503

Let's proceed to step 5:
503 goes into 4334 8 times with a remainder of 310.
Put 8 as the next digit of the answer. 
Result so far: 198.0
Deduct 4024 from 4334 and we're left with 310.
Take the next digit (8) from the dividend and append it to 310, then repeat: 3108 / 503

Let's proceed to step 6:
When dividing 3108 by 503, we get 6 with a remainder of 90.
Record the quotient 6 as the next digit in the result. 
Result so far: 1986.0
If we take 3018 away from 3108, we end up with 90.
Grab the next digit (8) from the dividend, add it to 90, then carry on: 908 / 503

Going ahead to step 7:
503 can be fit into 908 1 times, resulting in a remainder of 405.
Record the quotient 1 as the next digit in the result. 
Result so far: 19861.0
If we subtract 503 from 908, we get 405.
Include the next digit (0) from the dividend after 405, then repeat: 4050 / 503

Moving on to step 8:
503 goes into 4050 8 times with a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 198618.0
If we subtract 4024 from 4050, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
260 divided by 503 is 0 with a remainder of 260.
Use 0 as the next digit of our solution. 
Result so far: 198618.0
Subtract 0 from 260 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 10:
The number 503 fits into 2600 5 times, leaving a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 198618.05
If we subtract 2515 from 2600, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 11:
The number 503 fits into 850 1 times, leaving a remainder of 347.
The next digit of our result is 1. 
Result so far: 198618.051
If we subtract 503 from 850, we get 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Moving on to step 12:
503 goes into 3470 6 times with a remainder of 452.
Record the quotient 6 as the next digit in the result. 
Result so far: 198618.0516
The remainder is 452 after subtracting 3018 from 3470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Advancing to step 13:
When dividing 4520 by 503, we get 8 with a remainder of 496.
The number 8 becomes the next digit in our result. 
Result so far: 198618.05168
Deduct 4024 from 4520 and we're left with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 14:
503 can be fit into 4960 9 times, resulting in a remainder of 433.
Record the quotient 9 as the next digit in the result. 
Result so far: 198618.051689
If we subtract 4527 from 4960, we get 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Let's proceed to step 15:
The number 503 fits into 4330 8 times, leaving a remainder of 306.
Record the quotient 8 as the next digit in the result. 
Result so far: 198618.0516898
Subtract 4024 from 4330 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 16:
3060 divided by 503 is 6 with a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 198618.05168986
The remainder is 42 after subtracting 3018 from 3060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 198618.05168986 and a remainder of 4.2e-08.
