This page (1) reports 9 stops (between start and destination):

> The plane took off – for the 1st leg of the flight from Amsterdam to Batavia – on 30 April. The schedule: Budapest 30 April, Athens 1 May, Cairo 2 May, Baghdad 3 May, Jask 4 May, Jodhpur 5 May, Calcutta 6 May, Tavoy 7 May, Medan 8 May and arriving in Batavia on 9 May.

This page(2) claims a max speed of 190km/h. Budapest to Athens is 1130 km apart, so if the plane was flying around 150km/h, it's a 7 hour trip for that segment. Ouch. At least the passengers probably had a nice dinner and slept every night in a nice hotel...
