What is the process of sortition? When did Athenians use elections?

Explanation:

Athenian democracy developed in the 6th century BC out of what was then called isonomia (equality of law and political rights). Sortition was then the principal way of achieving this fairness. ... It is accepted as democratic when public offices are allocated by lot; and as oligarchic when they are filled by election.
