235030 ÷ 20 
The aim is to understand the frequency of 20 in 235030.

Let's proceed to step 1:
20 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 20

Moving on to step 2:
20 goes into 23 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 20 away from 23, we end up with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 20

Step 3:
35 divided by 20 is 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 20 away from 35, we end up with 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 20

Going ahead to step 4:
20 goes into 150 7 times with a remainder of 10.
The next digit of our result is 7. 
Result so far: 117.0
If we subtract 140 from 150, we get 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 20

Moving on to step 5:
103 divided by 20 is 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 1175.0
If we subtract 100 from 103, we get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 20

Moving on to step 6:
When dividing 30 by 20, we get 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 11751.0
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 7:
If we divide 100 by 20, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 11751.5
If we take 100 away from 100, we end up 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.

Advancing to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 11751.5
If we take 0 away from 0, we end up 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.
The number 0 becomes the next digit in our result. 
Result so far: 11751.5
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.

The final outcome is 11751.5, with a leftover of 0.0.
