How do I check that all the bricks are there in the smartest way?

I’ve received my largest LEGO order to date—250,000+ bricks. When dealing with such large quantities, is there a smart way to verify that everything is accounted for? Has anyone had experience "counting" them? Previously, I’ve received maybe 12,000 bricks, and I could count 100 of one type and weigh them, then weigh all the bricks of that type to see if it roughly matched. But I don’t have a scale that large. Maybe that’s still the solution, but I’d have to do it in smaller batches at a time....
