To divide up a short story, think about the flow of events. Maybe break it at the points where there's a significant shift in the story's direction or when a new element is introduced. You could also separate it based on the different emotional beats of the characters. For example, when they face a big challenge or have a breakthrough.
You can divide a short story based on plot points or character developments. Like, start with the introduction, then move to the rising action, followed by the climax and finally the resolution.
Well, one way to divide a short story is by looking at the different stages of the story arc. First, there's the setup to introduce the characters and the setting. Then, you have the conflict or problem that builds up the tension. The peak of that tension is the climax, and after that comes the resolution where everything gets sorted out. Another approach could be dividing it based on changes in the main character's emotions or decisions.
