We look at the division of 792715 by 20 
The aim is to understand the frequency of 20 in 792715.

Going ahead to step 1:
20 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 20

Step 2:
20 goes into 79 3 times with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 60 away from 79, we end up with 19.
Append the next digit (2) from the dividend to 19 and continue with: 192 / 20

Going ahead to step 3:
192 divided by 20 is 9 with a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Subtract 180 from 192 to get 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 20

Moving on to step 4:
The number 20 fits into 127 6 times, leaving a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 396.0
Deduct 120 from 127 and we're left with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 20

On to step 5:
20 goes into 71 3 times with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 3963.0
Subtract 60 from 71 to get 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 20

Moving on to step 6:
The number 20 fits into 115 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 39635.0
Subtract 100 from 115 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
The number 20 fits into 150 7 times, leaving a remainder of 10.
The next digit of our result is 7. 
Result so far: 39635.7
If we subtract 140 from 150, we 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.

Moving on to step 8:
20 goes into 100 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 39635.75
Deduct 100 from 100 and we're left 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 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 39635.75
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.

Moving on to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 39635.75
Subtract 0 from 0 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.

The quotient of the division is 39635.75, and the remainder is 0.0.
