665804 divided by 17 
The aim is to understand the frequency of 17 in 665804.

Advancing to step 1:
6 divided by 17 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 17

Going ahead to step 2:
If we divide 66 by 17, we get 3 and a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 51 from 66 and we're left with 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 17

Step 3:
17 can be fit into 155 9 times, resulting in a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we subtract 153 from 155, we get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 17

Let's proceed to step 4:
When dividing 28 by 17, we get 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 391.0
If we subtract 17 from 28, we get 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 17

Advancing to step 5:
17 goes into 110 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 3916.0
If we take 102 away from 110, we end up with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 17

Let's proceed to step 6:
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: 39164.0
If we take 68 away from 84, 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.

On to step 7:
17 can be fit into 160 9 times, resulting in a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 39164.9
The remainder is 7 after subtracting 153 from 160.
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 8:
When dividing 70 by 17, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 39164.94
The remainder is 2 after subtracting 68 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
If we divide 20 by 17, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 39164.941
If we subtract 17 from 20, we 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.

Going ahead to step 10:
When dividing 30 by 17, we get 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 39164.9411
Subtracting 17 from 30 leaves us 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 quotient of the division is 39164.9411, and the remainder is 0.00013.
