980223 ÷ 20 
The aim is to understand the frequency of 20 in 980223.

Step 1:
9 divided by 20 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 20

Let's proceed to step 2:
The number 20 fits into 98 4 times, leaving a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 80 from 98 and we're left with 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 20

Moving on to step 3:
20 goes into 180 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 49.0
Subtract 180 from 180 to get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 20

Advancing to step 4:
2 divided by 20 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 490.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 20

On to step 5:
20 can be fit into 22 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 4901.0
Subtract 20 from 22 to get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 20

Going ahead to step 6:
20 goes into 23 1 times with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 49011.0
Deduct 20 from 23 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
30 divided by 20 is 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 49011.1
Subtracting 20 from 30 leaves us 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.

Let's proceed to step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 49011.15
Subtracting 100 from 100 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:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 49011.15
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.

Going ahead to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 49011.15
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.

The quotient of the division is 49011.15, and the remainder is 0.0.
