Dynamic Demonstration of Division of Two Numbers (Advanced)

① This example demonstrates the division of two numbers, visualizing the quotient and remainder through dynamic graphics. ② Core mathematical concepts include integer division, factorization, 2D vector representation, parametric curves, and the upper/lower sums of Riemann integration. ③ Construction highlights: Random generates random dividend and divisor; Factors decomposes factors; Transpose and Dimension adjust matrix dimensions; Element extracts entries; Textfield and InputBox1 provide interactive input; If handles conditional logic; button1 drives step‑by‑step execution; objects a, m1, m2, l1, column_{m2}, d, s, c, row_{m2}, text1, text2 are coordinated to build the animation. ④ Suitable for high‑school topics “Numbers and Expressions”, “Vectors”, “Functions”, and for introductory university calculus lessons on division algorithms and Riemann sums.
