We look at the division of 415169 by 20 
The aim is to understand the frequency of 20 in 415169.

On to step 1:
20 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 20

Step 2:
41 divided by 20 is 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 40 from 41 to get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 20

Moving on to step 3:
20 can be fit into 15 0 times, resulting in a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 20

Going ahead to step 4:
If we divide 151 by 20, we get 7 and a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 207.0
Subtracting 140 from 151 leaves us with 11.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 20

Step 5:
20 goes into 116 5 times with a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 2075.0
Subtract 100 from 116 to get 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 20

Going ahead to step 6:
20 goes into 169 8 times with a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 20758.0
If we subtract 160 from 169, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
20 can be fit into 90 4 times, resulting in a remainder of 10.
The next digit of our result is 4. 
Result so far: 20758.4
Deduct 80 from 90 and we're left 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.

Advancing to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 20758.45
Deduct 100 from 100 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.

Going ahead to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20758.45
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 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20758.45
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.

In conclusion, the division gives 20758.45 with a balance of 0.0.
