We divide 663704 by 17
We want to figure out the number of times 663704 can be divided by 17.

Going ahead to step 1:
The number 17 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 17

Going ahead to step 2:
The number 17 fits into 66 3 times, leaving a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 51 from 66, we get 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 17

Moving on to step 3:
153 divided by 17 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 39.0
If we take 153 away from 153, we end up with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 17

Moving on to step 4:
If we divide 7 by 17, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 390.0
If we subtract 0 from 7, we get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 17

Going ahead to step 5:
70 divided by 17 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 3904.0
Deduct 68 from 70 and we're left with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 17

On to step 6:
24 divided by 17 is 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 39041.0
Subtracting 17 from 24 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
17 can be fit into 70 4 times, resulting in a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 39041.4
Deduct 68 from 70 and we're left 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.

Advancing to step 8:
The number 17 fits into 20 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 39041.41
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.

Going ahead to step 9:
If we divide 30 by 17, we get 1 and a remainder of 13.
The next digit of our result is 1. 
Result so far: 39041.411
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.

Our division results in 39041.411 with a remaining 0.0013.
