There aren't usually many domains where a process can't be described as a series of steps. Deciding what those are called, and structuring data in such a way that it each of those steps works sensibly can be challenging, but that is the process of making code comprehensible.
I can remember as a novice that I would write an entire program in a single, many-thousand line function, unable to see where the boundaries between functions should be. With experience and expertise in the domain, it becomes easier to see where those should be.
