Hex Division Table Generator

Generates a configurable NxN division table (default 0-F) rendered as a real HTML table, with row/column headers in hexadecimal and every cell showing the hex quotient plus remainder of row divided by column (e.g. "3 r 2"); the column-0 divide-by-zero case is shown as "—". A free online tool from Staaarter, right in your browser.

Overview

Introduction

Division tables are less commonly seen than multiplication or addition tables, but they're a genuinely useful reference for quickly checking a hex quotient and remainder without doing long division by hand.

This tool generates a configurable NxN grid where the row and column headers are hex digits and each cell shows the full quotient-and-remainder result of dividing row by column, with the undefined divide-by-zero column clearly marked.

What Is Hex Division Table Generator?

A division table where both axes are labeled with hex digits (0-F by default) and every cell shows the integer quotient and remainder of the row header divided by the column header, both expressed in hexadecimal.

It's rendered as a real HTML table, since a genuine table element is the clearest way to present a two-axis reference grid with a compound (quotient + remainder) cell value.

How Hex Division Table Generator Works

For a table of size N, the headers are the hex representations of 0 through N-1.

Every cell at row r and column c (for c > 0) computes the integer quotient `Math.floor(r / c)` and remainder `r % c` in decimal, then formats each as hex, showing just the quotient if the remainder is zero, or "quotient r remainder" otherwise.

The column-0 case is special-cased to the placeholder "—" for every row, since division by zero has no defined quotient or remainder.

When To Use Hex Division Table Generator

Use it as a quick-reference chart for checking a hex division result, especially the remainder, which is easy to get wrong doing hex long division by hand.

It's also a useful teaching aid for demonstrating how integer division and modulo behave when both operands and results are expressed in base 16.

Features

Advantages

  • Shows both quotient and remainder in one cell, matching how division results are normally described.
  • Clearly and explicitly marks the divide-by-zero column rather than showing a misleading value.
  • Rendered as a genuine, easy-to-scan table element with configurable size.

Limitations

  • Capped at 32x32 to keep the table a reasonable size to render and read.
  • Only non-negative integer division is covered; there's no negative-number or fractional-division mode.

Examples

A division with a remainder

Input

row 9, column 2 (default 0-F table)

Output

4 r 1

9 divided by 2 is 4 with a remainder of 1 in decimal, both values shown directly in hex since they're already single digits.

The divide-by-zero column

Input

row 7, column 0 (default 0-F table)

Output

Column 0 always shows the placeholder dash, since division by zero is undefined regardless of the row value.

Best Practices & Notes

Best Practices

  • Read the divide-by-zero column's dash as "undefined", not as zero or infinity.
  • Use the quotient-and-remainder pair together, the remainder alone doesn't tell you the full division result.
  • Stick with the default 0-F size for the most common quick-reference use case.

Developer Notes

Quotient and remainder are computed with ordinary JavaScript decimal arithmetic (`Math.floor(r / c)` and `r % c`) then each formatted with `.toString(16).toUpperCase()`; column 0 is special-cased before that arithmetic runs, avoiding a division-by-zero `Infinity`/`NaN` result from ever reaching the display layer.

Hex Division Table Generator Use Cases

  • Quick-reference chart for checking a hex division's quotient and remainder
  • Teaching or learning how integer division and modulo work in hexadecimal
  • Spot-checking a manually computed hex long-division result

Common Mistakes

  • Misreading the divide-by-zero dash as meaning zero, rather than undefined.
  • Forgetting the remainder is also shown in hex, not decimal, when comparing against a manual calculation.
  • Reading a header digit as decimal instead of hex, e.g. treating column "A" as 10 columns further right than it actually is.

Tips

  • Cross-check a cell's quotient-and-remainder pair with `row = quotient * column + remainder` in decimal to verify your own hand-computed hex division.
  • Use the default 0-F size unless you specifically need larger, two-digit hex headers.
