We look at the division of 288029 by 20 
The aim is to understand the frequency of 20 in 288029.

Moving on to step 1:
If we divide 2 by 20, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 20

Going ahead to step 2:
20 can be fit into 28 1 times, resulting in a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 20 from 28, we get 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 20

Advancing to step 3:
20 can be fit into 88 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 80 from 88, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 20

Let's proceed to step 4:
20 can be fit into 80 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 144.0
If we subtract 80 from 80, we get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 20

Advancing to step 5:
20 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 1440.0
If we subtract 0 from 2, we get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 20

On to step 6:
When dividing 29 by 20, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 14401.0
If we take 20 away from 29, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
If we divide 90 by 20, we get 4 and a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 14401.4
If we take 80 away from 90, we end up 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.

Advancing to step 8:
100 divided by 20 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 14401.45
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 number 0 becomes the next digit in our result. 
Result so far: 14401.45
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 10:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 14401.45
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.

The final outcome is 14401.45, with a leftover of 0.0.
