We're dividing 612338 by 20 
The aim is to understand the frequency of 20 in 612338.

Going ahead to step 1:
20 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 20

Step 2:
The number 20 fits into 61 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 60 from 61 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 20

On to step 3:
20 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 30.0
If we subtract 0 from 12, we get 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 20

Advancing to step 4:
20 can be fit into 123 6 times, resulting in a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 306.0
Subtract 120 from 123 to get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 20

On to step 5:
If we divide 33 by 20, we get 1 and a remainder of 13.
The next digit of our result is 1. 
Result so far: 3061.0
If we take 20 away from 33, we end up with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 20

On to step 6:
If we divide 138 by 20, we get 6 and a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 30616.0
Deduct 120 from 138 and we're left 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.

On to step 7:
180 divided by 20 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 30616.9
Subtracting 180 from 180 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.

Moving on to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 30616.9
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.

Let's proceed to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 30616.9
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.

The final outcome is 30616.9, with a leftover of 0.0.
