306239 ÷ 17 
We want to divide 306239 by 17.

Let's proceed to step 1:
If we divide 3 by 17, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 17

Moving on to step 2:
17 can be fit into 30 1 times, resulting in a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 17 from 30 and we're left with 13.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 17

On to step 3:
When dividing 136 by 17, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 136 from 136, we get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 17

Step 4:
17 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 180.0
Subtract 0 from 2 to get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 17

Going ahead to step 5:
23 divided by 17 is 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1801.0
If we subtract 17 from 23, we get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 17

Moving on to step 6:
The number 17 fits into 69 4 times, leaving a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 18014.0
Deduct 68 from 69 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
If we divide 10 by 17, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 18014.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
When dividing 100 by 17, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 18014.05
If we take 85 away from 100, we end up 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.

Step 9:
The number 17 fits into 150 8 times, leaving a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 18014.058
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.

Going ahead to step 10:
If we divide 140 by 17, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 18014.0588
The remainder is 4 after subtracting 136 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 18014.0588 with a remainder of 4e-05.
