We look at the division of 924857 by 20 
The aim is to understand the frequency of 20 in 924857.

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
If we take 0 away from 9, we end up with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 20

Moving on to step 2:
20 goes into 92 4 times with 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 (4) from the dividend and append it to 12, then repeat: 124 / 20

Moving on to step 3:
20 can be fit into 124 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 46.0
The remainder is 4 after subtracting 120 from 124.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 20

Advancing to step 4:
When dividing 48 by 20, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 462.0
If we subtract 40 from 48, we get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 20

Advancing to step 5:
20 can be fit into 85 4 times, resulting in a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 4624.0
Subtract 80 from 85 to get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 20

Going ahead to step 6:
The number 20 fits into 57 2 times, leaving a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 46242.0
If we take 40 away from 57, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
20 goes into 170 8 times with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 46242.8
Subtract 160 from 170 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.

Advancing to step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 46242.85
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.

Moving on to step 9:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 46242.85
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 46242.85
If we take 0 away from 0, 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.

The final outcome is 46242.85, with a leftover of 0.0.
