We're dividing 774726 by 17 
The aim is to understand the frequency of 17 in 774726.

On to step 1:
The number 17 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 17

Step 2:
The number 17 fits into 77 4 times, leaving a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 68 from 77, we get 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 17

Step 3:
17 goes into 94 5 times with a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 45.0
The remainder is 9 after subtracting 85 from 94.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 17

Let's proceed to step 4:
If we divide 97 by 17, we get 5 and a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 455.0
Deduct 85 from 97 and we're left with 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 17

Step 5:
122 divided by 17 is 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 4557.0
Subtracting 119 from 122 leaves us with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 17

Step 6:
If we divide 36 by 17, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 45572.0
Subtracting 34 from 36 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.

On to step 7:
17 goes into 20 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 45572.1
The remainder is 3 after subtracting 17 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
If we divide 30 by 17, we get 1 and a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 45572.11
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.

After the division, we end up with 45572.11 and a remainder of 0.013.
