We look at the division of 448793 by 17 
The aim is to understand the frequency of 17 in 448793.

Let's proceed to step 1:
17 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 17

Step 2:
If we divide 44 by 17, we get 2 and a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 34 from 44, we get 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 17

Step 3:
When dividing 108 by 17, we get 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtracting 102 from 108 leaves us with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 17

Moving on to step 4:
17 can be fit into 67 3 times, resulting in a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 263.0
Deduct 51 from 67 and we're left with 16.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 17

Moving on to step 5:
The number 17 fits into 169 9 times, leaving a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 2639.0
If we take 153 away from 169, we end up with 16.
Fetch the next digit (3) from the dividend, attach it to 16 and continue: 163 / 17

Let's proceed to step 6:
17 can be fit into 163 9 times, resulting in a remainder of 10.
The next digit of our result is 9. 
Result so far: 26399.0
If we take 153 away from 163, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
100 divided by 17 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 26399.5
Subtract 85 from 100 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
When dividing 150 by 17, we get 8 with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 26399.58
If we take 136 away from 150, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
140 divided by 17 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 26399.588
If we take 136 away from 140, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 26399.588 with a remaining 0.0004.
