Let's divide 722505 by 17
The aim is to understand the frequency of 17 in 722505.

On to step 1:
If we divide 7 by 17, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 17

Advancing to step 2:
If we divide 72 by 17, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 4 after subtracting 68 from 72.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 17

Step 3:
17 can be fit into 42 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 42.0
If we take 34 away from 42, we end up with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 17

On to step 4:
The number 17 fits into 85 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 425.0
The remainder is 0 after subtracting 85 from 85.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 17

Going ahead to step 5:
When dividing 0 by 17, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4250.0
Subtract 0 from 0 to get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 17

Advancing to step 6:
When dividing 5 by 17, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 42500.0
If we subtract 0 from 5, we 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.

Going ahead to step 7:
The number 17 fits into 50 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 42500.2
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.

Going ahead to step 8:
17 can be fit into 160 9 times, resulting in a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 42500.29
Subtract 153 from 160 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 9:
17 goes into 70 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 42500.294
Subtracting 68 from 70 leaves us 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.

Moving on to step 10:
17 can be fit into 20 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 42500.2941
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.

Step 11:
The number 17 fits into 30 1 times, leaving a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 42500.29411
If we take 17 away from 30, we end up 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 result is 42500.29411 with a remainder of 1.3e-05.
