번 is a common counter that counts behavior or actions, and is not directly counted with a noun in a sentence. Putting a number before "번" creates an adverb that tells you how many times something was done. It is an adverb, so 를/을 is usually not attached to it.
저는 어제 학교에 세 번 갔어요 - I went to school three times yesterday
저는 그 영화를 다섯 번 봤어요 - I saw that movie five times
저는 오늘 두 번 운동할 것입니다 - I will exercise twice (two times) today
