Divide the Body?

This pattern is really unclear. I’ve never made a sweater or sweater like thing before. I understand the patter up until it says to “divide the body” for the back of the shrug. What am I supposed to do? Does that mean that I stop knitting in the round at my marker? Am I supposed to switch to straight needles?


This is the pattern I am looking at.

Yes, you begin by working the left cuff in the round, then begin to work flat. You can knit flat with the circs, it’s easier than with straights because they’re more flexible and the first few rows can be a bit tight.
