We're dividing 787984 by 17 
The aim is to understand the frequency of 17 in 787984.

Step 1:
The number 17 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 17

Going ahead to step 2:
The number 17 fits into 78 4 times, leaving a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 68 from 78 leaves us with 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 17

Step 3:
17 goes into 107 6 times with a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
Subtracting 102 from 107 leaves us with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 17

Let's proceed to step 4:
17 can be fit into 59 3 times, resulting in a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 463.0
Deduct 51 from 59 and we're left with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 17

On to step 5:
88 divided by 17 is 5 with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 4635.0
The remainder is 3 after subtracting 85 from 88.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 17

Let's proceed to step 6:
34 divided by 17 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 46352.0
Deduct 34 from 34 and we're left with 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: 46352.0
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.

On to step 8:
The number 17 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 46352.0
If we take 0 away from 0, we end up with 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 46352.0 with a remainder of 0.0.
