We look at the division of 408061 by 17 
The aim is to understand the frequency of 17 in 408061.

On to step 1:
If we divide 4 by 17, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 17

Step 2:
17 goes into 40 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 34 from 40 leaves us with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 17

Let's proceed to step 3:
When dividing 68 by 17, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtract 68 from 68 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 17

On to step 4:
When dividing 0 by 17, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 240.0
If we take 0 away from 0, we end up with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 17

Moving on to step 5:
17 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 2400.0
If we take 0 away from 6, we end up with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 17

On to step 6:
17 can be fit into 61 3 times, resulting in a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 24003.0
The remainder is 10 after subtracting 51 from 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
17 can be fit into 100 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 24003.5
If we take 85 away from 100, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
The number 17 fits into 150 8 times, leaving a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 24003.58
If we take 136 away from 150, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
140 divided by 17 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 24003.588
If we take 136 away from 140, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 24003.588 with a balance of 0.0004.
