This interactive tool teaches children division through visual grouping. Users input a dividend and divisor, then click a button to see the calculation displayed with any remainder. The visualization uses D3 v7 to generate SVG circles representing items, arranged into group containers with dynamically computed heights. A colorful, child-friendly interface with dashed borders and labeled groups shows how items distribute equally, while leftover items appear in a distinct red "Leftovers" group for visual clarity. The tool also provides a narrative explanation of the division result in simple terms.
