Practising Long Division: Interactive Random Division Drills

① This example demonstrates an interactive long division practice tool that randomly generates dividends and divisors, guiding users step-by-step through the vertical division algorithm with immediate correctness feedback. ② Core math concepts include integer division, remainders, the relationship between quotient and divisor, and place-value decomposition (ones, tens, hundreds, thousands). ③ Construction highlights: GeoGebra commands such as Random generate random divisors and dividends, Div and Mod compute quotient and remainder, Segment and Vector draw the division bracket and arrows, Textfield provides input boxes, a button (button1) triggers checking, and multiple text objects (text1~text10) display the question, progress, and feedback. ④ Suitable for upper elementary or middle school students to practice long division, and useful for teachers in classroom demonstrations or for self-paced learning, reinforcing division rules and place-value understanding.
