We're dividing 492548 by 20 
The aim is to understand the frequency of 20 in 492548.

Moving on to step 1:
When dividing 4 by 20, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 20

Step 2:
49 divided by 20 is 2 with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 40 from 49 to get 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 20

Step 3:
20 goes into 92 4 times with a remainder of 12.
The next digit of our result is 4. 
Result so far: 24.0
If we take 80 away from 92, we end up with 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 20

Let's proceed to step 4:
If we divide 125 by 20, we get 6 and a remainder of 5.
The next digit of our result is 6. 
Result so far: 246.0
The remainder is 5 after subtracting 120 from 125.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 20

Let's proceed to step 5:
54 divided by 20 is 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 2462.0
If we subtract 40 from 54, we get 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 20

Step 6:
If we divide 148 by 20, we get 7 and a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 24627.0
Subtract 140 from 148 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
80 divided by 20 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 24627.4
Subtracting 80 from 80 leaves us 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.

Let's proceed to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 24627.4
Deduct 0 from 0 and we're left 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.

Advancing to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 24627.4
Subtracting 0 from 0 leaves us 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 result is 24627.4 with a remainder of 0.0.
