It won't take you far to becoming a dancer (7)

I believe the answer is:

onestep

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

'it won't take you far to' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'a dancer' is the wordplay.
'a' becomes 'one'.
'dancer' becomes 'step' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'one'+'step'='ONESTEP'

'becoming' acts as a link.

Can you help me to learn more?

(Another definition for onestep that I've seen is " (Very short?) ballroom dance".)

I've seen this clue in The Irish News.
