666409 divided by 17 
Let's see how many times 17 fits into 666409.

Advancing to step 1:
If we divide 6 by 17, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 17

Let's proceed to step 2:
If we divide 66 by 17, we get 3 and a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 51 from 66 leaves us with 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 17

On to step 3:
17 goes into 156 9 times with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we subtract 153 from 156, we get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 17

Moving on to step 4:
17 goes into 34 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 392.0
Subtracting 34 from 34 leaves us with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 17

Advancing to step 5:
If we divide 0 by 17, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3920.0
Subtract 0 from 0 to get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 17

On to step 6:
When dividing 9 by 17, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 39200.0
If we take 0 away from 9, we end up 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 7:
17 can be fit into 90 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 39200.5
If we subtract 85 from 90, we 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.

Moving on to step 8:
If we divide 50 by 17, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 39200.52
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.

Moving on to step 9:
If we divide 160 by 17, we get 9 and a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 39200.529
If we take 153 away from 160, we end up 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.

Let's proceed to step 10:
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: 39200.5294
Subtracting 68 from 70 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.

Step 11:
20 divided by 17 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 39200.52941
Deduct 17 from 20 and we're left 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.

On to step 12:
17 goes into 30 1 times with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 39200.529411
The remainder is 13 after subtracting 17 from 30.
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 39200.529411 with a remaining 1.3e-06.
