We divide 780565 by 20
The aim is to understand the frequency of 20 in 780565.

Advancing to step 1:
20 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 20

Moving on to step 2:
If we divide 78 by 20, we get 3 and a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 18 after subtracting 60 from 78.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 20

Going ahead to step 3:
180 divided by 20 is 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Subtract 180 from 180 to get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 20

Going ahead to step 4:
5 divided by 20 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 390.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 20

Let's proceed to step 5:
If we divide 56 by 20, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 3902.0
Subtract 40 from 56 to get 16.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 20

Moving on to step 6:
20 goes into 165 8 times with a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 39028.0
If we take 160 away from 165, we end up 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 can be fit into 50 2 times, resulting in a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 39028.2
Subtract 40 from 50 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 goes into 100 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 39028.25
Deduct 100 from 100 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.

On to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 39028.25
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.

Step 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 39028.25
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.

In conclusion, the division gives 39028.25 with a balance of 0.0.
