We divide 122878 by 17
The aim is to understand the frequency of 17 in 122878.

Moving on to step 1:
If we divide 1 by 17, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 17

Let's proceed to step 2:
The number 17 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 17

Moving on to step 3:
17 goes into 122 7 times with a remainder of 3.
The next digit of our result is 7. 
Result so far: 7.0
If we take 119 away from 122, we end up with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 17

Advancing to step 4:
17 can be fit into 38 2 times, resulting in a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
If we subtract 34 from 38, we get 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 17

Let's proceed to step 5:
17 goes into 47 2 times with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 722.0
Subtract 34 from 47 to get 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 17

Step 6:
17 can be fit into 138 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 7228.0
Subtracting 136 from 138 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.

Moving on to step 7:
17 can be fit into 20 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 7228.1
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.

Step 8:
If we divide 30 by 17, we get 1 and a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 7228.11
Subtract 17 from 30 to 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 7228.11 with a remaining 0.013.
