We're dividing 730002 by 20 
The aim is to understand the frequency of 20 in 730002.

Step 1:
20 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 20

On to step 2:
If we divide 73 by 20, we get 3 and a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 60 from 73 to get 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 20

On to step 3:
130 divided by 20 is 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Subtracting 120 from 130 leaves us with 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 20

Moving on to step 4:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 365.0
The remainder is 0 after subtracting 100 from 100.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 20

Advancing to step 5:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3650.0
If we subtract 0 from 0, we get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 20

On to step 6:
When dividing 2 by 20, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 36500.0
If we subtract 0 from 2, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
If we divide 20 by 20, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 36500.1
Deduct 20 from 20 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.

Let's proceed to step 8:
0 divided by 20 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 36500.1
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 9:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 36500.1
Deduct 0 from 0 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.

The final result is 36500.1 with a remainder of 0.0.
