We're dividing 707669 by 17 
The aim is to understand the frequency of 17 in 707669.

Going ahead to step 1:
If we divide 7 by 17, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 17

Moving on to step 2:
17 goes into 70 4 times with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 68 away from 70, we end up with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 17

On to step 3:
The number 17 fits into 27 1 times, leaving a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 41.0
Subtract 17 from 27 to get 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 17

On to step 4:
When dividing 106 by 17, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 416.0
If we subtract 102 from 106, we get 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 17

On to step 5:
17 goes into 46 2 times with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 4162.0
If we subtract 34 from 46, we get 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 17

Going ahead to step 6:
The number 17 fits into 129 7 times, leaving a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 41627.0
The remainder is 10 after subtracting 119 from 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
100 divided by 17 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 41627.5
If we subtract 85 from 100, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
150 divided by 17 is 8 with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 41627.58
Deduct 136 from 150 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
If we divide 140 by 17, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 41627.588
The remainder is 4 after subtracting 136 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 41627.588, with a leftover of 0.0004.
