That's similar to how Dickens wrote A Tale of Two Cities[1].
"The 45-chapter novel was published in 31 weekly installments in Dickens' new literary periodical titled All the Year Round. From April 1859 to November 1859"
Likely more people will read a book in short chunks because it looks less imposing. And it gives you an opportunity to "pivot" your story if it's not going well.
Dickens' method had more do with economics. Most of his audience was not especially well off, and books were VERY expensive back then, as in over $100 in today's money.
