We look at the division of 7647 by 17 
The aim is to understand the frequency of 17 in 7647.

Step 1:
17 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 17

Moving on to step 2:
17 goes into 76 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 68 from 76, we get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 17

Step 3:
17 can be fit into 84 4 times, resulting in a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
If we subtract 68 from 84, we get 16.
Bring next digit (7) of the dividend behind the 16 and repeat the process: 167 / 17

Step 4:
The number 17 fits into 167 9 times, leaving a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 449.0
The remainder is 14 after subtracting 153 from 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 5:
If we divide 140 by 17, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 449.8
Subtracting 136 from 140 leaves us 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.

On to step 6:
17 can be fit into 40 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 449.82
Subtract 34 from 40 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
60 divided by 17 is 3 with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 449.823
Subtract 51 from 60 to 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.

Advancing to step 8:
90 divided by 17 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 449.8235
Subtract 85 from 90 to get 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 can be fit into 50 2 times, resulting in a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 449.82352
Subtract 34 from 50 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
160 divided by 17 is 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 449.823529
Deduct 153 from 160 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 11:
70 divided by 17 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 449.8235294
Deduct 68 from 70 and we're left 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.

Advancing to step 12:
20 divided by 17 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 449.82352941
Subtracting 17 from 20 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 449.82352941 with a remainder of 3e-09.
