    Design a function that determines how many distinct difficulty sub-levels can be created for a learning module based on its complexity rating, where each valid sub-level must evenly divide the module's overall complexity score. The number of possible sub-levels will help the adaptive learning system create appropriate progression steps for students working through the material.
