As a singer, she's in Division One (4)

I believe the answer is:

diva

I'm a little stuck... Click here to teach me more about this clue!

'division one' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.

'as a singer she's' is the wordplay.
I cannot really understand how this works, but
'a' is present in the answer.
'she' could be 'di' and 'di' is found within the answer.
A single letter 'v' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

'in' is the link.
