660519 ÷ 17 
Our goal is to divide 660519 by 17.

Going ahead to step 1:
17 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 17

Going ahead to step 2:
17 goes into 66 3 times with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 51 from 66 leaves us with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 17

Moving on to step 3:
17 goes into 150 8 times with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Subtract 136 from 150 to get 14.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 17

Going ahead to step 4:
When dividing 145 by 17, we get 8 with a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 388.0
The remainder is 9 after subtracting 136 from 145.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 17

Advancing to step 5:
17 goes into 91 5 times with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 3885.0
Deduct 85 from 91 and we're left with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 17

On to step 6:
If we divide 69 by 17, we get 4 and a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 38854.0
If we subtract 68 from 69, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
The number 17 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 38854.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
17 can be fit into 100 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 38854.05
Subtracting 85 from 100 leaves us 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:
17 goes into 150 8 times with a remainder of 14.
The next digit of our result is 8. 
Result so far: 38854.058
Subtract 136 from 150 to 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.

Moving on to step 10:
When dividing 140 by 17, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 38854.0588
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.

After the division, we end up with 38854.0588 and a remainder of 4e-05.
