We look at the division of 686315 by 75 
Our goal is to divide 686315 by 75.

Step 1:
When dividing 6 by 75, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 75

Advancing to step 2:
68 divided by 75 is 0 with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Grab the next digit (6) from the dividend, add it to 68, then carry on: 686 / 75

Let's proceed to step 3:
The number 75 fits into 686 9 times, leaving a remainder of 11.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 11 after subtracting 675 from 686.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 75

Going ahead to step 4:
75 can be fit into 113 1 times, resulting in a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 91.0
Subtracting 75 from 113 leaves us with 38.
Append the next digit (1) from the dividend to 38 and continue with: 381 / 75

Step 5:
75 goes into 381 5 times with a remainder of 6.
The next digit of our result is 5. 
Result so far: 915.0
If we take 375 away from 381, we end up with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 75

On to step 6:
The number 75 fits into 65 0 times, leaving a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 9150.0
Subtract 0 from 65 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 7:
75 goes into 650 8 times with a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 9150.8
Subtracting 600 from 650 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
500 divided by 75 is 6 with a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 9150.86
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
75 goes into 500 6 times with a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 9150.866
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 9150.866 with a remainder of 0.005.
