We're dividing 460660 by 20 
The aim is to understand the frequency of 20 in 460660.

Advancing to step 1:
4 divided by 20 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 20

Let's proceed to step 2:
20 can be fit into 46 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 40 away from 46, we end up with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 20

Going ahead to step 3:
60 divided by 20 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtracting 60 from 60 leaves us with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 20

Moving on to step 4:
6 divided by 20 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 230.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 20

On to step 5:
When dividing 66 by 20, we get 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 2303.0
Deduct 60 from 66 and we're left with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 20

Step 6:
60 divided by 20 is 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 23033.0
Subtracting 60 from 60 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.

On to step 7:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 23033.0
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.

Advancing to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 23033.0
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.

After the division, we end up with 23033.0 and a remainder of 0.0.
