If we divide 17 by 665, we get 0 and a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 665

On to step 3:
If we divide 172 by 665, we get 0 and a remainder of 172.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 172 after subtracting 0 from 172.
Take the next digit (0) from the dividend and append it to 172, then repeat: 1720 / 665

Going ahead to step 4:
1720 divided by 665 is 2 with a remainder of 390.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1330 from 1720, we get 390.
Bring next digit (9) of the dividend behind the 390 and repeat the process: 3909 / 665

Advancing to step 5:
3909 divided by 665 is 5 with a remainder of 584.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we subtract 3325 from 3909, we get 584.
Include the next digit (3) from the dividend after 584, then repeat: 5843 / 665

Going ahead to step 6:
5843 divided by 665 is 8 with a remainder of 523.
Use 8 as the next digit of our solution. 
Result so far: 258.0
Deduct 5320 from 5843 and we're left with 523.
Take the next digit (5) from the dividend and append it to 523, then repeat: 5235 / 665

On to step 7:
The number 665 fits into 5235 7 times, leaving a remainder of 580.
Use 7 as the next digit of our solution. 
Result so far: 2587.0
The remainder is 580 after subtracting 4655 from 5235.
Append the next digit (0) from the dividend to 580 and continue with: 5800 / 665

Going ahead to step 8:
When dividing 5800 by 665, we get 8 with a remainder of 480.
Write down 8 as next digit of the result. 
Result so far: 25878.0
Deduct 5320 from 5800 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 9:
665 can be fit into 4800 7 times, resulting in a remainder of 145.
Put 7 as the next digit of the answer. 
Result so far: 25878.7
Subtract 4655 from 4800 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 10:
665 can be fit into 1450 2 times, resulting in a remainder of 120.
Record the quotient 2 as the next digit in the result. 
Result so far: 25878.72
Subtract 1330 from 1450 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 11:
665 goes into 1200 1 times with a remainder of 535.
Use 1 as the next digit of our solution. 
Result so far: 25878.721
Subtracting 665 from 1200 leaves us with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Step 12:
5350 divided by 665 is 8 with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 25878.7218
Subtract 5320 from 5350 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
665 can be fit into 300 0 times, resulting in a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 25878.7218
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 14:
665 can be fit into 3000 4 times, resulting in a remainder of 340.
Use 4 as the next digit of our solution. 
Result so far: 25878.721804
Deduct 2660 from 3000 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 15:
When dividing 3400 by 665, we get 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 25878.7218045
Subtracting 3325 from 3400 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 16:
If we divide 750 by 665, we get 1 and a remainder of 85.
Use 1 as the next digit of our solution. 
Result so far: 25878.72180451
Subtracting 665 from 750 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

After the division, we end up with 25878.72180451 and a remainder of 8.5e-08.
