We're dividing 302339 by 17 
Let's see how many times 17 fits into 302339.

Going ahead to step 1:
The number 17 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 17

Let's proceed to step 2:
If we divide 30 by 17, we get 1 and a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 17 away from 30, we end up with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 17

On to step 3:
When dividing 132 by 17, we get 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtracting 119 from 132 leaves us with 13.
Fetch the next digit (3) from the dividend, attach it to 13 and continue: 133 / 17

Advancing to step 4:
If we divide 133 by 17, we get 7 and a remainder of 14.
The next digit of our result is 7. 
Result so far: 177.0
Subtracting 119 from 133 leaves us with 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 17

On to step 5:
If we divide 143 by 17, we get 8 and a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 1778.0
If we subtract 136 from 143, we get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 17

Going ahead to step 6:
79 divided by 17 is 4 with a remainder of 11.
The next digit of our result is 4. 
Result so far: 17784.0
Subtract 68 from 79 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
When dividing 110 by 17, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 17784.6
If we subtract 102 from 110, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
17 can be fit into 80 4 times, resulting in a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 17784.64
If we subtract 68 from 80, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
If we divide 120 by 17, we get 7 and a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 17784.647
Subtracting 119 from 120 leaves us 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.

Advancing to step 10:
17 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 17784.647
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
17 goes into 100 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 17784.64705
If we subtract 85 from 100, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 12:
When dividing 150 by 17, we get 8 with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 17784.647058
If we take 136 away from 150, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 13:
17 goes into 140 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 17784.6470588
Deduct 136 from 140 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.

The final result is 17784.6470588 with a remainder of 4e-08.
