Symbol for long division (using HTML and/or CSS)

Is there a way in HTML/CSS to display the traditional long division symbol? Something similar to what's shown here: .

I found this Unicode character () that might work, but I'm concerned not everyone will have the necessary font installed on their computer to see it.

I also attempted this code snippet below, but it isn't displaying consistently on Chrome and Firefox...

4<span style="text-decoration: overline;"><span style="font-size: 14px">)</span>84</span>

This should be showing 84 divided by 4 with the long division box included.

Any suggestions?

The concept of long division has been a traditional method for teaching arithmetic in many school settings. It is often used to visually explain the steps of integer division. Representing long division using HTML and CSS is challenging without resorting to images, either large ones showing the entire process or smaller ones displaying individual components like numbers and operators. Websites like http://www.mathisfun.com/long_division.html use this method. Others, such as http://en.wikipedia.org/wiki/Long_division, rely on preformatted text and basic ASCII symbols, resulting in a less visually appealing and non-accessible display.

If you choose to use an image, be sure to provide descriptive alt text that conveys the relevant information. This description may need to be somewhat lengthy, such as

alt="long division with divisor 4, dividend 84"
.

Constructing intricate mathematical expressions like long divisions solely with HTML and CSS can be quite difficult due to their inherent limitations in representing two-dimensional notation. Even something relatively simpler, like displaying a square root expression neatly, can pose challenges. While Unicode character U+27CC LONG DIVISION theoretically allows for textual representation of long division, practical implementation faces obstacles including font support issues and software limitations. Browsers struggle to render complex long division expressions accurately, particularly when extending over multiple digits or numbers.

When working with HTML5, an exciting feature is the ability to directly incorporate MathML. MathML 3 introduces the useful <mlongdiv> element:

<figure>
  <math>
    <mlongdiv>
      <mn>4</mn>
      <mn></mn>
      <mn>84</mn>
    </mlongdiv>
  </math>
  <figcaption>
    This will render as a long division in web browsers that support MathML 3.
  </figcaption>
</figure>

If you're utilizing MathML 2, one approach is using Javascript coupled with LaTeX, like MathJax. Take a look at this long division example which employs MathJax TeX parser for expressions like \longdiv{84}{4}.
