Verbs of motion with the prefix до- denote relocation of a person or object within a fairly large space: coming near, reaching an object or goal.
The prefix до- denotes approaching an object which was not far away originally. Verbs with the prefix до- answer the questions До чего? До кого? (Reached what? Reached whom?) and are often used together with the preposition до- after them.
Remember
Verbs of motion with prefixes have one peculiarity: the Present Tense usually requires a verb from the “ходить” group, as they show that the action is taking place right now. Verbs from the “идти” group are used in the Past Tense to show a completed action or in the Future Tense to indicate a potential result.
