521281 ÷ 17 
Let's see how many times 17 fits into 521281.

Let's proceed to step 1:
17 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 17

On to step 2:
17 can be fit into 52 3 times, resulting in a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 51 from 52 leaves us with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 17

Step 3:
17 can be fit into 11 0 times, resulting in a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we take 0 away from 11, we end up with 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 17

Going ahead to step 4:
112 divided by 17 is 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 306.0
Deduct 102 from 112 and we're left with 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 17

Moving on to step 5:
If we divide 108 by 17, we get 6 and a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 3066.0
If we subtract 102 from 108, we get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 17

Step 6:
17 can be fit into 61 3 times, resulting in a remainder of 10.
The next digit of our result is 3. 
Result so far: 30663.0
If we subtract 51 from 61, we 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.

On to step 7:
100 divided by 17 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 30663.5
The remainder is 15 after subtracting 85 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
The number 17 fits into 150 8 times, leaving a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 30663.58
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.

Advancing to step 9:
17 goes into 140 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 30663.588
If we subtract 136 from 140, we get 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 30663.588 with a remainder of 0.0004.
