560279 ÷ 20 
The aim is to understand the frequency of 20 in 560279.

Let's proceed to step 1:
5 divided by 20 is 0 with 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:
If we divide 56 by 20, we get 2 and a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 40 from 56 and we're left with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 20

Going ahead to step 3:
20 can be fit into 160 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtracting 160 from 160 leaves us with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 20

Moving on to step 4:
The number 20 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 280.0
If we subtract 0 from 2, we get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 20

Advancing to step 5:
If we divide 27 by 20, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 2801.0
Subtract 20 from 27 to get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 20

Going ahead to step 6:
When dividing 79 by 20, we get 3 with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 28013.0
The remainder is 19 after subtracting 60 from 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
When dividing 190 by 20, we get 9 with a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 28013.9
Deduct 180 from 190 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.

Moving on to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 28013.95
If we subtract 100 from 100, 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.

Moving on to step 9:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 28013.95
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.

Advancing to step 10:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 28013.95
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.

Our division results in 28013.95 with a remaining 0.0.
