602028 divided by 20 
The aim is to understand the frequency of 20 in 602028.

Going ahead to step 1:
20 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 20

Let's proceed to step 2:
20 goes into 60 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 0 after subtracting 60 from 60.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 20

On to step 3:
2 divided by 20 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 30.0
If we subtract 0 from 2, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 20

Let's proceed to step 4:
The number 20 fits into 20 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 301.0
If we take 20 away from 20, we end up with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 20

Going ahead to step 5:
The number 20 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 3010.0
If we subtract 0 from 2, we get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 20

On to step 6:
28 divided by 20 is 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 30101.0
Subtracting 20 from 28 leaves us with 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:
When dividing 80 by 20, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 30101.4
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.

Step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 30101.4
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.

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: 30101.4
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.

After the division, we end up with 30101.4 and a remainder of 0.0.
