In Dutch:
vijfenzestig (65) - zesenvijftig (56) = 9 > 0
Not sure why William found such a large number. We're only a small country after all ...
In German:
vierundfünfzig (54) - fünfundvierzig (45) = 9 > 0
In Russian:
тридцать два (32) - двадцать три (23) = 9 > 0
In French (only slightly smaller than William's entry, and it's not a digit anagram):
deux cent vingt (220) - cent vingt-deux (122) = 98 > 0
