We're dividing 686597 by 17 
Let's see how many times 17 fits into 686597.

Going ahead to step 1:
When dividing 6 by 17, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 17

Let's proceed to step 2:
17 goes into 68 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 0 after subtracting 68 from 68.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 17

Going ahead to step 3:
6 divided by 17 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtract 0 from 6 to get 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 17

Let's proceed to step 4:
17 can be fit into 65 3 times, resulting in a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 403.0
Subtract 51 from 65 to get 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 17

Going ahead to step 5:
The number 17 fits into 149 8 times, leaving a remainder of 13.
Put 8 as the next digit of the answer. 
Result so far: 4038.0
Deduct 136 from 149 and we're left with 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 17

Moving on to step 6:
The number 17 fits into 137 8 times, leaving a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 40388.0
Subtracting 136 from 137 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.

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: 40388.0
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.

Advancing to step 8:
17 goes into 100 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 40388.05
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.

On to step 9:
When dividing 150 by 17, we get 8 with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 40388.058
The remainder is 14 after subtracting 136 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
17 goes into 140 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 40388.0588
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 40388.0588 with a remainder of 4e-05.
