We look at the division of 412117 by 20 
The aim is to understand the frequency of 20 in 412117.

On to step 1:
20 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 20

Moving on to step 2:
The number 20 fits into 41 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 40 from 41 and we're left with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 20

Step 3:
12 divided by 20 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 20

Let's proceed to step 4:
If we divide 121 by 20, we get 6 and a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 206.0
The remainder is 1 after subtracting 120 from 121.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 20

Moving on to step 5:
If we divide 11 by 20, we get 0 and a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 2060.0
Subtract 0 from 11 to get 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 20

Let's proceed to step 6:
20 can be fit into 117 5 times, resulting in a remainder of 17.
Put 5 as the next digit of the answer. 
Result so far: 20605.0
Subtracting 100 from 117 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
The number 20 fits into 170 8 times, leaving a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 20605.8
If we take 160 away from 170, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 20605.85
If we take 100 away from 100, 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:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20605.85
Subtract 0 from 0 to 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.

Let's proceed to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20605.85
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 20605.85 with a balance of 0.0.
