20920931 divided by 502 
The aim is to understand the frequency of 502 in 20920931.

Moving on to step 1:
The number 502 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 502

Advancing to step 2:
If we divide 20 by 502, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 502

Step 3:
502 goes into 209 0 times with a remainder of 209.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 209 and we're left with 209.
Append the next digit (2) from the dividend to 209 and continue with: 2092 / 502

Moving on to step 4:
The number 502 fits into 2092 4 times, leaving a remainder of 84.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 2008 from 2092 and we're left with 84.
Take the next digit (0) from the dividend and append it to 84, then repeat: 840 / 502

Let's proceed to step 5:
502 can be fit into 840 1 times, resulting in a remainder of 338.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Subtracting 502 from 840 leaves us with 338.
Take the next digit (9) from the dividend and append it to 338, then repeat: 3389 / 502

Let's proceed to step 6:
When dividing 3389 by 502, we get 6 with a remainder of 377.
The next digit of our result is 6. 
Result so far: 416.0
Subtract 3012 from 3389 to get 377.
Append the next digit (3) from the dividend to 377 and continue with: 3773 / 502

Step 7:
When dividing 3773 by 502, we get 7 with a remainder of 259.
Use 7 as the next digit of our solution. 
Result so far: 4167.0
Deduct 3514 from 3773 and we're left with 259.
Take the next digit (1) from the dividend and append it to 259, then repeat: 2591 / 502

On to step 8:
The number 502 fits into 2591 5 times, leaving a remainder of 81.
The next digit of our result is 5. 
Result so far: 41675.0
Subtract 2510 from 2591 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 9:
The number 502 fits into 810 1 times, leaving a remainder of 308.
The next digit of our result is 1. 
Result so far: 41675.1
The remainder is 308 after subtracting 502 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 10:
502 can be fit into 3080 6 times, resulting in a remainder of 68.
Put 6 as the next digit of the answer. 
Result so far: 41675.16
Deduct 3012 from 3080 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 11:
If we divide 680 by 502, we get 1 and a remainder of 178.
Write down 1 as next digit of the result. 
Result so far: 41675.161
Subtract 502 from 680 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

On to step 12:
The number 502 fits into 1780 3 times, leaving a remainder of 274.
Record the quotient 3 as the next digit in the result. 
Result so far: 41675.1613
If we subtract 1506 from 1780, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 13:
If we divide 2740 by 502, we get 5 and a remainder of 230.
Use 5 as the next digit of our solution. 
Result so far: 41675.16135
Deduct 2510 from 2740 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 14:
2300 divided by 502 is 4 with a remainder of 292.
Use 4 as the next digit of our solution. 
Result so far: 41675.161354
Subtract 2008 from 2300 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Let's proceed to step 15:
If we divide 2920 by 502, we get 5 and a remainder of 410.
Put 5 as the next digit of the answer. 
Result so far: 41675.1613545
Subtracting 2510 from 2920 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 16:
4100 divided by 502 is 8 with a remainder of 84.
The number 8 becomes the next digit in our result. 
Result so far: 41675.16135458
The remainder is 84 after subtracting 4016 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final result is 41675.16135458 with a remainder of 8.4e-08.
