We look at the division of 729153 by 20 
The aim is to understand the frequency of 20 in 729153.

Going ahead to step 1:
20 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 20

Advancing to step 2:
72 divided by 20 is 3 with a remainder of 12.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 60 from 72 leaves us with 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 20

Step 3:
20 goes into 129 6 times with a remainder of 9.
The next digit of our result is 6. 
Result so far: 36.0
Subtracting 120 from 129 leaves us with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 20

Going ahead to step 4:
91 divided by 20 is 4 with a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 364.0
The remainder is 11 after subtracting 80 from 91.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 20

Advancing to step 5:
The number 20 fits into 115 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 3645.0
If we subtract 100 from 115, we get 15.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 20

Moving on to step 6:
When dividing 153 by 20, we get 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 36457.0
If we take 140 away from 153, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
20 can be fit into 130 6 times, resulting in a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 36457.6
Subtract 120 from 130 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On 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: 36457.65
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.

On to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 36457.65
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.

Let's proceed to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 36457.65
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.

The quotient of the division is 36457.65, and the remainder is 0.0.
