Hi Kezia,
Since we don´t have the context, in this case, "le" could refer to the third person (él/ella) or the formal form (Usted). In Spanish, the use of reflexive verbs (with the reflexive pronoun) is quite extensive. In this case, we could translate in English with "How is it going?" with the difference that English uses the neutral "it" pronoun and Spanish likes to refer to the person. A literal translation could be "how is it going with you"?
I hope it helps!
