We don't know precisely, but the division of Parshas (weekly portions) goes back to Mishnaic times (c.1800 years ago), if not earlier. The word "parsha" can also mean "paragraph". The Torah's paragraphs (not chapters) go all the way back to Moses.
The Torah is divided into weekly readings, called "parshas". One system divides the text so the entire Torah is read in one year, another system is based on a three-year cycle. So at least in theory, all portions are read in equal amounts.
A parasha is a weekly Torah portion read in synagogues as part of the Jewish religious practice. It typically covers a specific section of the Torah and is read aloud during services, with commentary and discussion often following the reading.
