Division as the Inverse of Multiplication
Dividing is undoing equal grouping: the dividend equals divisor times quotient, and repeated subtraction reaches the same answer. Learners meet equal sharing, the multiply-then-divide two-step, and the relation that a larger dividend yields a larger quotient. This unknown-factor view is the basis for all later division reasoning.
