Remember
Character ⊘
Unicode U+2298
Hex entity ⊘
Decimal ⊘

CSS escape \2298
All of these produce the same glyph: ⊘. Prefer ⊘ or a typed ⊘ in hand-written HTML; use numeric forms when generating markup.

Use ⊘ (hex), ⊘ (decimal), ⊘ (named), or the CSS escape \2298 in the content property. All render ⊘. You can also paste ⊘ directly when your file is UTF-8.
U+2298 (hex 2298, decimal 8856). Unicode names it CIRCLED DIVISION SLASH. It belongs to the Mathematical Operators block.
Yes. ⊘ maps to U+2298. Prefer ⊘ in hand-written HTML; numeric forms are useful in generated markup.
⊘ (U+2298) is circled division slash. ÷ (U+00F7) is the common division sign. ∅ (U+2205) is empty set — a circle with a slash that looks similar but means something else.
HTML entities (⊘, ⊘, or ⊘) go in markup. The CSS escape \2298 is used in stylesheets (usually in the content property of ::before/::after). Both render ⊘.
Use it in math or formal notation when you need this exact circled division operator. Prefer ÷ or / for everyday division.
