We look at the division of 4604818 by 20 
The aim is to understand the frequency of 20 in 4604818.

Going ahead to step 1:
20 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 20

Step 2:
20 goes into 46 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 40 away from 46, we end up with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 20

Step 3:
If we divide 60 by 20, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtract 60 from 60 to get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 20

Step 4:
When dividing 4 by 20, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 230.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 20

Let's proceed to step 5:
48 divided by 20 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2302.0
Subtracting 40 from 48 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 20

Going ahead to step 6:
The number 20 fits into 81 4 times, leaving a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 23024.0
The remainder is 1 after subtracting 80 from 81.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 20

On to step 7:
20 can be fit into 18 0 times, resulting in a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 230240.0
Subtracting 0 from 18 leaves us 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 8:
20 goes into 180 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 230240.9
If we subtract 180 from 180, we 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.

Moving on to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 230240.9
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.

On to step 10:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 230240.9
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.

In conclusion, the division gives 230240.9 with a balance of 0.0.
