Long Division and Remainders

Mrs. Gordian reviews long division, solving two problems: 1834 ÷ 6 and 189054 ÷ 9. She explains handling remainders in division story problems, using a luncheon example to illustrate options for dealing with remainders: ignoring, reporting as a fraction/decimal, or rounding up.
