We're dividing 714480 by 20 
The aim is to understand the frequency of 20 in 714480.

Let's proceed to step 1:
If we divide 7 by 20, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 20

Let's proceed to step 2:
If we divide 71 by 20, we get 3 and a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 60 away from 71, we end up with 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 20

Step 3:
The number 20 fits into 114 5 times, leaving a remainder of 14.
The next digit of our result is 5. 
Result so far: 35.0
If we take 100 away from 114, we end up with 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 20

Moving on to step 4:
144 divided by 20 is 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 357.0
The remainder is 4 after subtracting 140 from 144.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 20

Going ahead to step 5:
48 divided by 20 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 3572.0
The remainder is 8 after subtracting 40 from 48.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 20

On to step 6:
The number 20 fits into 80 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 35724.0
Deduct 80 from 80 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.

Step 7:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 35724.0
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.

Step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 35724.0
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.

Our division results in 35724.0 with a remaining 0.0.
