We look at the division of 882658 by 20 
The aim is to understand the frequency of 20 in 882658.

Advancing to step 1:
The number 20 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 20

Advancing to step 2:
The number 20 fits into 88 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 80 from 88, we get 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 20

Let's proceed to step 3:
If we divide 82 by 20, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 44.0
Deduct 80 from 82 and we're left with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 20

On to step 4:
26 divided by 20 is 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 441.0
Subtracting 20 from 26 leaves us with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 20

On to step 5:
20 goes into 65 3 times with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 4413.0
If we take 60 away from 65, we end up with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 20

Step 6:
The number 20 fits into 58 2 times, leaving a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 44132.0
If we take 40 away from 58, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
When dividing 180 by 20, we get 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 44132.9
Deduct 180 from 180 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.

Moving on to step 8:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 44132.9
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.

Advancing to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 44132.9
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 44132.9 and a remainder of 0.0.
