We're dividing 399855 by 17 
The aim is to understand the frequency of 17 in 399855.

Moving on to step 1:
The number 17 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 17

Moving on to step 2:
The number 17 fits into 39 2 times, leaving a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 34 from 39 and we're left with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 17

Moving on to step 3:
59 divided by 17 is 3 with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtract 51 from 59 to get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 17

Going ahead to step 4:
17 can be fit into 88 5 times, resulting in a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 235.0
Deduct 85 from 88 and we're left with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 17

Let's proceed to step 5:
35 divided by 17 is 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2352.0
If we subtract 34 from 35, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 17

Moving on to step 6:
17 can be fit into 15 0 times, resulting in a remainder of 15.
The next digit of our result is 0. 
Result so far: 23520.0
If we subtract 0 from 15, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
17 can be fit into 150 8 times, resulting in a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 23520.8
Subtract 136 from 150 to get 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 8:
17 can be fit into 140 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 23520.88
The remainder is 4 after subtracting 136 from 140.
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 23520.88 with a balance of 0.004.
