With 76-Down, individually

ONE AT …

Think of how you might describe taking turns in a sequence, like counting off people in a group. The answer starts with the first number you'd say.

This clue is split across two parts—here, you get "ONE AT" and the rest ("A TIME") comes at 76-Down. Together, they form the phrase "ONE AT A TIME," meaning individually. The clue hints at the answer being broken up, so you’ll need both parts to complete the full expression. It’s a straightforward charade-style clue where the answer is divided between two entries.
