Translation of "하나하나" in English

마음속에서 동작을 하나하나 재현했습니다.

as if I were truly performing in a virtual body in my mind.

‎아주 작은 흔적 하나하나 ‎사소한 행동을 모두 살펴보고 ‎다른 동물과의 소통 방식을 ‎전부 연구하고 싶었어요

to understand every little tiny mark, every little behavior, every species and what they're doing, how they're interacting.
