We look at the division of 80276 by 20 
The aim is to understand the frequency of 20 in 80276.

Advancing to step 1:
When dividing 8 by 20, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 20

Let's proceed to step 2:
20 can be fit into 80 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 80 from 80 leaves us with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 20

Going ahead to step 3:
20 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 40.0
If we subtract 0 from 2, we get 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 20

Step 4:
If we divide 27 by 20, we get 1 and a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 401.0
Subtract 20 from 27 to get 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 20

On to step 5:
20 goes into 76 3 times with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 4013.0
Deduct 60 from 76 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 6:
If we divide 160 by 20, we get 8 and a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 4013.8
Deduct 160 from 160 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.

Step 7:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4013.8
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.

Step 8:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4013.8
If we subtract 0 from 0, 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.

The quotient of the division is 4013.8, and the remainder is 0.0.
