We look at the division of 768253 by 17 
The aim is to understand the frequency of 17 in 768253.

Step 1:
17 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 17

Moving on to step 2:
When dividing 76 by 17, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 8 after subtracting 68 from 76.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 17

Step 3:
The number 17 fits into 88 5 times, leaving a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtract 85 from 88 to get 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 17

Step 4:
The number 17 fits into 32 1 times, leaving a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 451.0
The remainder is 15 after subtracting 17 from 32.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 17

Step 5:
155 divided by 17 is 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 4519.0
Subtract 153 from 155 to get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 17

Going ahead to step 6:
23 divided by 17 is 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 45191.0
If we take 17 away from 23, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
The number 17 fits into 60 3 times, leaving a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 45191.3
If we subtract 51 from 60, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 8:
When dividing 90 by 17, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 45191.35
Subtracting 85 from 90 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
17 goes into 50 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 45191.352
Deduct 34 from 50 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
17 can be fit into 160 9 times, resulting in a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 45191.3529
Subtract 153 from 160 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 11:
17 can be fit into 70 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 45191.35294
If we subtract 68 from 70, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 12:
17 goes into 20 1 times with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 45191.352941
Subtract 17 from 20 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
When dividing 30 by 17, we get 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 45191.3529411
Deduct 17 from 30 and we're left 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.

Our division results in 45191.3529411 with a remaining 1.3e-07.
