We look at the division of 686743 by 17 
Our goal is to divide 686743 by 17.

Advancing to step 1:
The number 17 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 17

Let's proceed to step 2:
17 can be fit into 68 4 times, resulting in 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.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 17

Moving on to step 3:
17 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 40.0
Subtract 0 from 6 to get 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 17

Moving on to step 4:
When dividing 67 by 17, we get 3 with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 403.0
Subtract 51 from 67 to get 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 17

On to step 5:
If we divide 164 by 17, we get 9 and a remainder of 11.
The next digit of our result is 9. 
Result so far: 4039.0
Subtracting 153 from 164 leaves us with 11.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 17

Step 6:
When dividing 113 by 17, we get 6 with a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 40396.0
Deduct 102 from 113 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
When dividing 110 by 17, we get 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 40396.6
Deduct 102 from 110 and we're left with 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:
The number 17 fits into 80 4 times, leaving a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 40396.64
Subtract 68 from 80 to 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.

Step 9:
17 goes into 120 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 40396.647
The remainder is 1 after subtracting 119 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 10:
If we divide 10 by 17, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 40396.647
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.

Moving on to step 11:
100 divided by 17 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 40396.64705
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.

Going ahead to step 12:
The number 17 fits into 150 8 times, leaving a remainder of 14.
The next digit of our result is 8. 
Result so far: 40396.647058
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.

Step 13:
17 can be fit into 140 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 40396.6470588
If we take 136 away from 140, we end up 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 40396.6470588 with a remainder of 4e-08.
