DMSCB is a useful mnemonic device that will assist your students in mastering the "process" of long division, as it can be tedious for some.
This product comes with a poster illustrating how to use DMSCB and 16 long division problems (no remainders)/task cards that students can work through independently.
Laminate the cards and place them in a zip lock bag, along with dry erase markers and socks, and PRESTO! You have a perfect Math Center for your classroom that you don't have to continually re-create.
This product can also serve as a quick and easy way for the teacher, to run an informal assessment on students, checking for understanding of the concept/skill in remedial small groups.
