Let's divide 628624 by 17
The aim is to understand the frequency of 17 in 628624.

Going ahead to step 1:
If we divide 6 by 17, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 17

Step 2:
62 divided by 17 is 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 51 from 62 leaves us with 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 17

Advancing to step 3:
17 goes into 118 6 times with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
If we subtract 102 from 118, we get 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 17

Going ahead to step 4:
The number 17 fits into 166 9 times, leaving a remainder of 13.
The next digit of our result is 9. 
Result so far: 369.0
Subtract 153 from 166 to get 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 17

On to step 5:
17 goes into 132 7 times with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 3697.0
Deduct 119 from 132 and we're left with 13.
Fetch the next digit (4) from the dividend, attach it to 13 and continue: 134 / 17

Advancing to step 6:
17 can be fit into 134 7 times, resulting in a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 36977.0
Deduct 119 from 134 and we're left with 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 7:
The number 17 fits into 150 8 times, leaving a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 36977.8
If we subtract 136 from 150, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
17 goes into 140 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 36977.88
Subtract 136 from 140 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 36977.88, and the remainder is 0.004.
