Filling the place value board with drag and drop

Hello, community,
I am just starting to think about filling a place value table with the number range up to one million in the individual places using drag and drop and I am at a loss at the moment. Doing everything by hand, i.e. generating numbers that are then sorted into units, tens, hundreds, thousands, hundreds of thousands and millions, seems rather tedious to me.
Maybe someone has a bright idea.
