Let's divide 929931 by 20
The aim is to understand the frequency of 20 in 929931.

Advancing to step 1:
20 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 20

Moving on to step 2:
If we divide 92 by 20, we get 4 and a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 12 after subtracting 80 from 92.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 20

Step 3:
The number 20 fits into 129 6 times, leaving a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
If we subtract 120 from 129, we get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 20

On to step 4:
20 goes into 99 4 times with a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 464.0
Subtracting 80 from 99 leaves us with 19.
Append the next digit (3) from the dividend to 19 and continue with: 193 / 20

Going ahead to step 5:
193 divided by 20 is 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 4649.0
Deduct 180 from 193 and we're left with 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 20

Advancing to step 6:
20 can be fit into 131 6 times, resulting in a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 46496.0
The remainder is 11 after subtracting 120 from 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
110 divided by 20 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 46496.5
Subtract 100 from 110 to 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.

Step 8:
20 goes into 100 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 46496.55
The remainder is 0 after subtracting 100 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 46496.55 and a remainder of 0.0.
