We're dividing 668478 by 17 
We want to figure out the number of times 668478 can be divided by 17.

Step 1:
When dividing 6 by 17, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 17

Let's proceed to step 2:
When dividing 66 by 17, we get 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 51 from 66, we get 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 17

Let's proceed to step 3:
If we divide 158 by 17, we get 9 and a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we take 153 away from 158, we end up with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 17

Moving on to step 4:
When dividing 54 by 17, we get 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 393.0
If we subtract 51 from 54, we get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 17

Let's proceed to step 5:
The number 17 fits into 37 2 times, leaving a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 3932.0
The remainder is 3 after subtracting 34 from 37.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 17

Let's proceed to step 6:
When dividing 38 by 17, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 39322.0
Deduct 34 from 38 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
If we divide 40 by 17, we get 2 and a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 39322.2
Subtracting 34 from 40 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
17 goes into 60 3 times with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 39322.23
Deduct 51 from 60 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
The number 17 fits into 90 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 39322.235
Subtract 85 from 90 to 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.

Step 10:
50 divided by 17 is 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 39322.2352
The remainder is 16 after subtracting 34 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
160 divided by 17 is 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 39322.23529
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.

Let's proceed to step 12:
17 can be fit into 70 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 39322.235294
If we subtract 68 from 70, we get 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 13:
The number 17 fits into 20 1 times, leaving a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 39322.2352941
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.

Advancing to step 14:
The number 17 fits into 30 1 times, leaving a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 39322.23529411
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 39322.23529411 and a remainder of 1.3e-08.
