So playing around with this it also works for multiplication with decimals using say a dashed line between the appropriate digits. The location can be read off by finding the intersection of the dashed lines and putting it in front of that column's digit. It's significantly less elegant, particularly when that column yields a multi-digit count but it does work visually. I'm sure I'm not the first person to realize this, but it's cool that decimals can be integrated into the method while keeping vaguely in the spirit of the idea.
