What are some reasons a play is divided into acts and scenes

In a performance or a drama, acts and scenes are vital in sequencing or separating the narration or story into manageable parts for the audience, the actors, and the people working behind the curtains. The division of the performance is also important for ensuring a good flow of the narration or story itself.

Explanation:

The act and the scene are both visible in the play’s script and performance. For instance, in script form, both the act and scene headings are styled with capital letters in order to have a visual and distinct separation of one progression to another for the actors as well as the other people involved.
