In an octahedral complex, how do the five d orbitals typically split?

Answer

Into a lower energy set ($t_{2g}$) and a higher energy set ($e_g$)

The interaction with six ligands in an octahedral geometry causes the d orbitals to split into two distinct energy groups: the lower energy $t_{2g}$ set and the higher energy $e_g$ set.
