Hi Reddy, you mean potential V is got by dividing the work performed W in taking a charge q coulombs?
By definition of electric potential at a point, we recall these lines
The electric potential is the work performed in taking unit positive charge from infinity to the point against the electric field.
So as we perform work W in taking q coulomb charge then we divide W by q to get the work to move one coulomb
Hence V = W/q
