What if the dealer is stationary, not changing its position at the end of a game?

In a normal game, as I know, the small blind is the first person from the left of the dealer and the big blind is the second person from the left of the dealer. Doing so with a fixed dealer, following the same rules would mean that the same two players to the left will be continuously small blind, and, respectively, big blind.

What if a dealer holds his/her position? How will the position of the blinds be changed if the dealer will not change at the end of every game? How will the 'cycle' work, if I want, progressively, every and each player to be small blind and big blind an equal amount of games?
