The default remedy isn't break up, it's 10% of the total worldwide turnover (20% for repeat offenders). The EU can very much fine Google or Apple (and already did so).
If break-up is not possible, retricting or prohibiting access to the EU market is quite possible.
Edit: also, on my dealings with Google, I am contracting with Google Ireland Limited, a company that the EU can break up.
