823171 ÷ 17 
The aim is to understand the frequency of 17 in 823171.

Moving on to step 1:
If we divide 8 by 17, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 17

Let's proceed to step 2:
When dividing 82 by 17, we get 4 with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 68 from 82 leaves us with 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 17

Advancing to step 3:
143 divided by 17 is 8 with a remainder of 7.
The next digit of our result is 8. 
Result so far: 48.0
Subtract 136 from 143 to get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 17

Advancing to step 4:
The number 17 fits into 71 4 times, leaving a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 484.0
The remainder is 3 after subtracting 68 from 71.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 17

Advancing to step 5:
37 divided by 17 is 2 with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 4842.0
Deduct 34 from 37 and we're left with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 17

Going ahead to step 6:
If we divide 31 by 17, we get 1 and a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 48421.0
Subtract 17 from 31 to get 14.
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 7:
17 goes into 140 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 48421.8
If we subtract 136 from 140, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
40 divided by 17 is 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 48421.82
Deduct 34 from 40 and we're left 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.

Advancing to step 9:
If we divide 60 by 17, we get 3 and a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 48421.823
Deduct 51 from 60 and we're left with 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 10:
90 divided by 17 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 48421.8235
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.

Step 11:
17 can be fit into 50 2 times, resulting in a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 48421.82352
The remainder is 16 after subtracting 34 from 50.
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 12:
When dividing 160 by 17, we get 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 48421.823529
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.

Advancing to step 13:
17 goes into 70 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 48421.8235294
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.

Going ahead to step 14:
17 goes into 20 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 48421.82352941
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.

The final result is 48421.82352941 with a remainder of 3e-09.
