We're dividing 565085 by 20 
The aim is to understand the frequency of 20 in 565085.

Let's proceed to step 1:
20 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 20

Moving on to step 2:
56 divided by 20 is 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 40 from 56 to get 16.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 20

Moving on to step 3:
20 goes into 165 8 times with a remainder of 5.
The next digit of our result is 8. 
Result so far: 28.0
If we subtract 160 from 165, we get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 20

Step 4:
When dividing 50 by 20, we get 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 282.0
Subtracting 40 from 50 leaves us with 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 20

On to step 5:
The number 20 fits into 108 5 times, leaving a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 2825.0
If we subtract 100 from 108, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 20

Moving on to step 6:
20 goes into 85 4 times with a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 28254.0
Deduct 80 from 85 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
20 goes into 50 2 times with a remainder of 10.
The next digit of our result is 2. 
Result so far: 28254.2
Deduct 40 from 50 and we're left with 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 goes into 100 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 28254.25
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:
When dividing 0 by 20, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 28254.25
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.

On to step 10:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 28254.25
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.

The quotient of the division is 28254.25, and the remainder is 0.0.
