842231 ÷ 17 
The aim is to understand the frequency of 17 in 842231.

Moving on to step 1:
If we divide 8 by 17, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 17

Step 2:
If we divide 84 by 17, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 68 from 84 leaves us with 16.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 17

Advancing to step 3:
The number 17 fits into 162 9 times, leaving a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Deduct 153 from 162 and we're left with 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 17

Moving on to step 4:
92 divided by 17 is 5 with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 495.0
If we take 85 away from 92, we end up with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 17

Let's proceed to step 5:
17 goes into 73 4 times with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 4954.0
The remainder is 5 after subtracting 68 from 73.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 17

Going ahead to step 6:
17 goes into 51 3 times with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 49543.0
Subtract 51 from 51 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
17 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 49543.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
17 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 49543.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 49543.0 with a remainder of 0.0.
