We look at the division of 814306 by 17 
The aim is to understand the frequency of 17 in 814306.

On to step 1:
17 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 17

Moving on to step 2:
81 divided by 17 is 4 with a remainder of 13.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 68 from 81 to get 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 17

Going ahead to step 3:
134 divided by 17 is 7 with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 47.0
Subtract 119 from 134 to get 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 17

On to step 4:
17 can be fit into 153 9 times, resulting in a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 479.0
Subtracting 153 from 153 leaves us with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 17

Let's proceed to step 5:
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: 4790.0
Deduct 0 from 0 and we're left with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 17

On to step 6:
The number 17 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 47900.0
Subtracting 0 from 6 leaves us 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.

On to step 7:
17 can be fit into 60 3 times, resulting in a remainder of 9.
The next digit of our result is 3. 
Result so far: 47900.3
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:
17 goes into 90 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 47900.35
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.

Advancing to step 9:
The number 17 fits into 50 2 times, leaving a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 47900.352
If we take 34 away from 50, we end up 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.

Going ahead to step 10:
17 goes into 160 9 times with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 47900.3529
If we take 153 away from 160, we end up 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.

On to step 11:
17 can be fit into 70 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 47900.35294
If we take 68 away from 70, we end up 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.

Step 12:
The number 17 fits into 20 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 47900.352941
Deduct 17 from 20 and we're left 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.

Advancing to step 13:
When dividing 30 by 17, we get 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 47900.3529411
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.

The final outcome is 47900.3529411, with a leftover of 1.3e-07.
