Division over Spanish article in Variety (9)
I believe the answer is:
selection
'variety' is the definition.
(I know that selection is a type of variety)
'division over spanish article in' is the wordplay.
'division' becomes 'section' (synonyms).
'over' is a reversal indicator.
'spanish article' becomes 'el' (the definite article 'the' in Spanish).
'in' indicates putting letters inside.
'el' back-to-front is 'le'.
'section' going around 'le' is 'SELECTION'.
(Other definitions for selection that I've seen before include "Choice, pick" , "Act of choosing" , "Horse tipped for betting" .)
