a division expression where both dividend and divisor are numbers (although typically called the numerator and denominator), and there is no implication that the division needs to be evaluated further. A more basic way to show division is to use the obelus (or division sign) in this manner: This form is infrequent except in basic arithmetic and discouraged for more complex arithmetic, due to being ambiguous. The obelus is also used alone to represent the division operation itself, for instance, as a label on a key of a calculator. In some non-English-speaking cultures, "a divided by b" is written . However, in English usage the colon is restricted to expressing the related concept of ratios (then "a is to b"). With a knowledge of multiplication tables, two numbers can be divided on paper using the method of long division. An abbreviated version of long division, short division, can be used for smaller divisors as well. A less systematic method — but which leads to a more holistic understanding of division in general — involves the concept of chunking. By allowing one to subtract more multiples from the partial remainder at each stage, more free-form methods can be developed as well. Alternatively, if the dividend has a fractional part (expressed as a decimal fraction), one can continue the algorithm past the ones' place as far as desired. If the divisor has a decimal fractional part, one can restate the problem by moving the decimal to the right in both numbers until the divisor has no fraction. To divide by a fraction, one can simply multiply by the reciprocal (reversing the position of the top and bottom parts) of that fraction, For example: Example Let us find the quotient of 272 and 8. Starting with the hundreds-digit, 2 is not divisible by 8. So, we must go to the tens digit, 7, and add 20 to 7, to get 27. In order to divide 27 and 8, we must subtract the dividend by the Greatest Common Divisor (GCD), that is, the largest positive integer that divides into each of the integers. The GCD of 27 and 8 is 24. Subtracting 24 from 27 gives you 3, so 3 should be written under the tens column. 8 is bigger than 3, so we must go to the ones-digit to continue the division, in which the number is 2. We put the 3 ahead
