Crossword Genius

Run a metro badly, producing fractional dividend (9)

Ross

I believe the answer is:

numerator

'fractional dividend' is the definition.
(I've seen this before)

'run a metro badly' is the wordplay.
'badly' is an anagram indicator (letters in the wrong order).
'run'+'a'+'metro'='runametro'
'runametro' with letters rearranged gives 'NUMERATOR'.

'producing' acts as a link.

(Other definitions for numerator that I've seen before include "Figure going over a line" , "the superior figure" , "One counts" , "Upper half of fraction" , "Top half of 1/2 , for example" .)

I've seen this clue in The Times.
