We look at the division of 10230 by 20 
The aim is to understand the frequency of 20 in 10230.

Step 1:
If we divide 1 by 20, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 20

Moving on to step 2:
20 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 20

Moving on to step 3:
If we divide 102 by 20, we get 5 and a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 100 from 102 to get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 20

Going ahead to step 4:
20 can be fit into 23 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Subtracting 20 from 23 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 20

Step 5:
The number 20 fits into 30 1 times, leaving a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 511.0
The remainder is 10 after subtracting 20 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 6:
When dividing 100 by 20, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 511.5
Subtract 100 from 100 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.

Moving on to step 7:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 511.5
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.

Moving on to step 8:
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: 511.5
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.

In conclusion, the division gives 511.5 with a balance of 0.0.
