I believe the answer is:

dealing

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

'doing business' is the definition.
(thesaurus)

'dutch capital and part of london' is the wordplay.
'dutch capital' becomes 'd' (I can't explain this - if you can you should believe this answer much more).
'and' means one lot of letters go next to another.
'part of london' becomes 'ealing' (I've seen this before).
'd'+'ealing'='DEALING'

Can you help me to learn more?

(Other definitions for dealing that I've seen before include "Coping" , "Distributing (cards)" , "Making trades (with cards?)" , "Trading" , "Giving out cards" .)
