Let's divide 437808 by 17
The aim is to understand the frequency of 17 in 437808.

Let's proceed to step 1:
When dividing 4 by 17, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 17

Let's proceed to step 2:
17 can be fit into 43 2 times, resulting in a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 34 from 43 to get 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 17

Advancing to step 3:
97 divided by 17 is 5 with a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Deduct 85 from 97 and we're left with 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 17

Going ahead to step 4:
When dividing 128 by 17, we get 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 257.0
If we subtract 119 from 128, we get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 17

On to step 5:
90 divided by 17 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 2575.0
If we take 85 away from 90, we end up with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 17

On to step 6:
58 divided by 17 is 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 25753.0
The remainder is 7 after subtracting 51 from 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
17 can be fit into 70 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 25753.4
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.

On to step 8:
If we divide 20 by 17, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 25753.41
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.

Let's proceed to step 9:
17 goes into 30 1 times with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 25753.411
Subtract 17 from 30 to get 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 25753.411, and the remainder is 0.0013.
