I looked up the process for developing pictures yourself, and I’m confused on what part of the process takes the negative from the roll, which is like what, an inch or so, and then enlarges it to become a 4×6 picture.
So how does it happen? What part of the developing process makes this happen?

In a darkroom, it’s done with a tool that’s quite literally called an enlarger. The negative is placed into a holder, inserted into the enlarger, a light shines through the negative and onto the photo paper below using controllable timing and exposure levels appropriate for the specific negative, and that photo paper is processed with chemicals to bring out the image.
Nothing! “Developing” the films just means making the film non-reactive to any light exposure
Once the film is developed you would need some kind of scanner printer to make the 4×6 photos
Before digital conversion they used an enlarger (think overhead projector) and special reactive paper and another set of chemicsls
You take the negative and put it in front of a light, which then projects the image onto a piece of paper, which you can then treat with photoreactive chemicals to get the positive image in the right colors. That projection allows you to size the image to basically any size you want.
It’s magnified with an enlarger, similar to how a movie projector will have light passing through a 35mm (or 70mm or whatever the film size is) onto a lens that magnifies and projects that tiny ass image on a big ass screen.
