Do any Jews believe that the human soul is a part of G-d or that G-d exists within people in a way?

Hi, I’m not Jewish, but I’m just here to learn. I know a lot of religions hold this idea that the soul is a part of G-d or that G-d is otherwise somehow contained within each person. I was wondering if this concept is compatible with Judaism. I was kind of thinking that maybe this would violate the idea that G-d is an absolute unity and indivisible though. Thank you in advance for your perspectives!
