Let's divide 278875 by 17
The aim is to understand the frequency of 17 in 278875.

Moving on to step 1:
If we divide 2 by 17, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 17

Going ahead to step 2:
If we divide 27 by 17, we get 1 and a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 10 after subtracting 17 from 27.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 17

Moving on to step 3:
108 divided by 17 is 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 102 away from 108, we end up with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 17

Moving on to step 4:
If we divide 68 by 17, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 164.0
Deduct 68 from 68 and we're left with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 17

Step 5:
When dividing 7 by 17, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 1640.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 17

On to step 6:
When dividing 75 by 17, we get 4 with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 16404.0
If we take 68 away from 75, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
When dividing 70 by 17, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 16404.4
Subtracting 68 from 70 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
20 divided by 17 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 16404.41
The remainder is 3 after subtracting 17 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
When dividing 30 by 17, we get 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 16404.411
If we subtract 17 from 30, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 16404.411 with a remaining 0.0013.
