99724828 ÷ 502 
The aim is to understand the frequency of 502 in 99724828.

Moving on to step 1:
If we divide 9 by 502, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 502

Advancing to step 2:
The number 502 fits into 99 0 times, leaving a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Fetch the next digit (7) from the dividend, attach it to 99 and continue: 997 / 502

Step 3:
502 goes into 997 1 times with a remainder of 495.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 502 from 997, we get 495.
Append the next digit (2) from the dividend to 495 and continue with: 4952 / 502

Step 4:
502 goes into 4952 9 times with a remainder of 434.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Deduct 4518 from 4952 and we're left with 434.
Append the next digit (4) from the dividend to 434 and continue with: 4344 / 502

Advancing to step 5:
502 can be fit into 4344 8 times, resulting in a remainder of 328.
Use 8 as the next digit of our solution. 
Result so far: 198.0
The remainder is 328 after subtracting 4016 from 4344.
Bring next digit (8) of the dividend behind the 328 and repeat the process: 3288 / 502

Step 6:
The number 502 fits into 3288 6 times, leaving a remainder of 276.
Write down 6 as next digit of the result. 
Result so far: 1986.0
Subtract 3012 from 3288 to get 276.
Append the next digit (2) from the dividend to 276 and continue with: 2762 / 502

Step 7:
502 goes into 2762 5 times with a remainder of 252.
Use 5 as the next digit of our solution. 
Result so far: 19865.0
Subtracting 2510 from 2762 leaves us with 252.
Fetch the next digit (8) from the dividend, attach it to 252 and continue: 2528 / 502

Let's proceed to step 8:
2528 divided by 502 is 5 with a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 198655.0
The remainder is 18 after subtracting 2510 from 2528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
The number 502 fits into 180 0 times, leaving a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 198655.0
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 10:
The number 502 fits into 1800 3 times, leaving a remainder of 294.
Use 3 as the next digit of our solution. 
Result so far: 198655.03
Subtract 1506 from 1800 to get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Advancing to step 11:
502 goes into 2940 5 times with a remainder of 430.
The next digit of our result is 5. 
Result so far: 198655.035
If we subtract 2510 from 2940, we get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 12:
If we divide 4300 by 502, we get 8 and a remainder of 284.
Record the quotient 8 as the next digit in the result. 
Result so far: 198655.0358
The remainder is 284 after subtracting 4016 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Step 13:
502 goes into 2840 5 times with a remainder of 330.
The next digit of our result is 5. 
Result so far: 198655.03585
Deduct 2510 from 2840 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 14:
502 can be fit into 3300 6 times, resulting in a remainder of 288.
Write down 6 as next digit of the result. 
Result so far: 198655.035856
Subtracting 3012 from 3300 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 15:
The number 502 fits into 2880 5 times, leaving a remainder of 370.
The number 5 becomes the next digit in our result. 
Result so far: 198655.0358565
If we take 2510 away from 2880, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 16:
502 can be fit into 3700 7 times, resulting in a remainder of 186.
The number 7 becomes the next digit in our result. 
Result so far: 198655.03585657
If we take 3514 away from 3700, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

The final result is 198655.03585657 with a remainder of 1.86e-07.
