Thank you for posting this in Microsoft Q&A.
As I understand you are trying to sync Division attribute for devices from on-premises Active directory to Entra ID using Entra connect.
You have already enabled this attribute in Entra ID connector. But still you are not seeing this attribute in Entra ID.
Division attribute is not an attribute which is synced to Entra ID by default. Below is the article which shows all the attributes that can be synced to Entra ID using Entra connect.
https://learn.microsoft.com/en-us/entra/identity/hybrid/connect/reference-connect-sync-attributes-synchronized
To sync attributes which are not part of Entra connect can be synced by enabling directory extension feature in Entra connect.

Once these attributes are synced to Azure they will be populated in the form of below syntax,
user.extension_9d98ed114c4840d298fad781915f27e4_division
You can use below Graph query to get information see these attributes in Entra ID.
