Puzzle 35 - Open sesame

-

I am writing a post after two months. 

Here is a locked question ;)

There is a number lock. You have to find the number to unlock it.

 And here are the results of various number combinations.

682 - one digit is right and in the right position.
614 - one digit is right but in the wrong position.
206 - two digits are right but both are in the wrong positions.
738 - all digits are wrong.
380 - one digit is right but in the wrong place

So what is the correct code to open the lock?

When a is equal to b, a-b is zero. You can not divide numbers by zero because division is only defined for non-zero numbers.
