What's my skateboarding stance?

i recently started skateing, well when i'm practiceing ollies and kicks flips on the carpet (the only moves i can do) i stand on my board so that my right leg is the one to do the pushing but when i try to ride my board down steep hills and on the street i feel more comfertable pushing with my left leg but i can't do tricks when i'm in that position. while i'm rideing and pushing my board i put my right foot like a inch infront of the back bolts i know i'm standing wrong can anyone explain to me how i'm soppose to position my feet when i'm rideing and pushing?
