The video tutorial explains partitive division using base 10 blocks. It demonstrates dividing 525 by 3 by modeling the number with base 10 blocks, dividing flats, exchanging them for rods, and then sharing rods and units equally among three groups. The process concludes with each group having 175, showing that 525 divided by 3 equals 175.
