Division results as in b / c = d

0 / 0 = impossible
Modulo 0,0 = 0 / 0 = impossible

Previous by b    Next by b

Previous by c    Next by c

Division is often shown in algebra and science by placing the dividend over the divisor with a horizontal line, also called a vinculum or fraction bar, between them. For example, a divided by b is written


This can be read out loud as "a divided by b" or "a over b". A way to express division all on one line is to write the dividend, or numerator then a slash, then the divisor, or denominator like this:


This is the usual way to specify division in most computer programming languages since it can easily be typed as a simple sequence of characters.

A typographical variation, which is halfway between these two forms, uses a solidus (fraction slash) but elevates the dividend, and lowers the divisor:


Any of these forms can be used to display a fraction. A fraction is a division expression where both dividend and divisor are integers (although typically called the numerator and denominator), and there is no implication that the division needs to be evaluated further.

A second way to show division is to use the obelus (or division sign), common in arithmetic, in this manner:

a ÷ b

This form is infrequent except in elementary arithmetic. The obelus is also used alone to represent the division operation itself, as for instance as a label on a key of a calculator.

In some non-English-speaking cultures, "a divided by b" is written a : b. However, in English usage the colon is restricted to expressing the related concept of ratios (then "a is to b").
