The word consists of 'dazu' (to it / with it) and 'gehörig' (belonging, from 'gehören' — to belong). It literally means 'belonging to it' and always refers to something that was mentioned earlier.
Sie kaufte ein neues Handy und die dazugehörige Hülle.
She bought a new phone and the associated case.
'Dazugehörig' (associated / corresponding) always needs a clear reference point in the sentence or context. The 'da-' in 'dazugehörig' works like a pointing finger indicating the main object.
Zuerst lesen Sie den Vertrag, dann unterschreiben Sie das dazugehörige Formular.
First read the contract, then sign the corresponding form.
This adjective is very often used in connection with documents, accessories, or parts. Typical nouns are 'Unterlagen' (documents), 'Anleitung' (instructions), 'Kabel' (cable), or 'Software' (software).

I have the device, but the associated charging cable has disappeared.

Zugehörig and dazugehörig both describe a connection with a whole. Zugehörig usually directly identifies the person, group, or thing concerned. Dazugehörig, by contrast, typically uses “dazu” to refer to something that has already been mentioned or is clear from the context.
