922939 ÷ 20 
The aim is to understand the frequency of 20 in 922939.

Let's proceed to step 1:
If we divide 9 by 20, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
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

Step 2:
20 can be fit into 92 4 times, resulting in a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 80 from 92 and we're left with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 20

Moving on to step 3:
The number 20 fits into 122 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
The remainder is 2 after subtracting 120 from 122.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 20

Moving on to step 4:
The number 20 fits into 29 1 times, leaving a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 461.0
Subtracting 20 from 29 leaves us with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 20

Advancing to step 5:
20 can be fit into 93 4 times, resulting in a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 4614.0
Subtract 80 from 93 to get 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 20

Going ahead to step 6:
20 goes into 139 6 times with a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 46146.0
The remainder is 19 after subtracting 120 from 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
20 can be fit into 190 9 times, resulting in a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 46146.9
The remainder is 10 after subtracting 180 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
20 goes into 100 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 46146.95
If we take 100 away from 100, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 46146.95
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 46146.95
If we subtract 0 from 0, we get 0.
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 46146.95 and a remainder of 0.0.
