We're dividing 381278 by 17 
The aim is to understand the frequency of 17 in 381278.

Moving on to step 1:
The number 17 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 17

Step 2:
The number 17 fits into 38 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 4 after subtracting 34 from 38.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 17

Advancing to step 3:
The number 17 fits into 41 2 times, leaving a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtract 34 from 41 to get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 17

Going ahead to step 4:
If we divide 72 by 17, we get 4 and a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 224.0
If we subtract 68 from 72, we get 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 17

Let's proceed to step 5:
When dividing 47 by 17, we get 2 with a remainder of 13.
The next digit of our result is 2. 
Result so far: 2242.0
If we take 34 away from 47, we end up with 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 17

Let's proceed to step 6:
If we divide 138 by 17, we get 8 and a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 22428.0
If we take 136 away from 138, we end up 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.

Step 7:
17 goes into 20 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 22428.1
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.

Advancing to step 8:
If we divide 30 by 17, we get 1 and a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 22428.11
Subtracting 17 from 30 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 22428.11 with a remainder of 0.013.
