Also it may be something from the group theory, I guess.

I've only seen Z refer to integers, but like what krassi said, we need the context as well.

Are you treating complex numbers? If yes, then Z represents a complex number of the form  z= x+yi.
And z/6z=x+yi/6(x+yi).
Rationalise:x+yi(x-yi)/6(x+yi)(x-yi)
                = (x^2+y^2)/6(x^2+y^2)
                 =1/6
NB!!! This is if you saw this under complex numbers.
