Firebase recently introduced the ability to update multiple locations with one update() call.

ref.child('contabilidad').once('value', function(snapshot) {
  var updates = {};
  snapshot.forEach(function(child) {
    updates[child.key()+'/pago'] = 0;
  });
  ref.child('contabilidad').update(updates);
});

Also see this blog post on how to use this feature for atomic client-side fan-out.
