We look at the division of 752718 by 20 
The aim is to understand the frequency of 20 in 752718.

Moving on to step 1:
When dividing 7 by 20, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 20

Moving on to step 2:
The number 20 fits into 75 3 times, leaving a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 60 from 75 and we're left with 15.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 20

Moving on to step 3:
20 goes into 152 7 times with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Deduct 140 from 152 and we're left with 12.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 20

Going ahead to step 4:
20 goes into 127 6 times with a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 376.0
The remainder is 7 after subtracting 120 from 127.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 20

Step 5:
71 divided by 20 is 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 3763.0
If we subtract 60 from 71, we get 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 20

Step 6:
When dividing 118 by 20, we get 5 with a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 37635.0
Deduct 100 from 118 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
20 goes into 180 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 37635.9
If we take 180 away from 180, 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.

On to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 37635.9
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.

Advancing to 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: 37635.9
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.

In conclusion, the division gives 37635.9 with a balance of 0.0.
