Long division - Wikipedia Long division In arithmetic, long division is a standard division algorithm suitable for dividing multi-digit Hindu-Arabic numerals (positional notation) that is simple enough to perform by hand It breaks down a division problem into a series of easier steps
Division (mathematics) - Wikipedia Division is one of the four basic operations of arithmetic The other operations are addition, subtraction, and multiplication What is being divided is called the dividend, which is divided by the divisor, and the result is called the quotient At an elementary level the division of two natural numbers is, among other possible interpretations, the process of calculating the number of times
Division algorithm - Wikipedia A division algorithm is an algorithm which, given two integers N and D (respectively the numerator and the denominator), computes their quotient and or remainder, the result of Euclidean division
Divisibility rule - Wikipedia A divisibility rule is a shorthand and useful way of determining whether a given integer is divisible by a fixed divisor without performing the division, usually by examining its digits Although there are divisibility tests for numbers in any radix, or base, and they are all different, this article presents rules and examples only for decimal, or base 10, numbers Martin Gardner explained and
Numeric precision in Microsoft Excel - Wikipedia As with other spreadsheets, Microsoft Excel works only to limited accuracy because it retains only a certain number of figures to describe numbers (it has limited precision) With some exceptions regarding erroneous values, infinities, and denormalized numbers, Excel calculates in double-precision floating-point format from the IEEE 754 specification [1] (besides numbers, Excel uses a few
Division by two - Wikipedia In binary arithmetic, division by two can be performed by a bit shift operation that shifts the number one place to the right This is a form of strength reduction optimization For example, 1101001 in binary (the decimal number 105), shifted one place to the right, is 110100 (the decimal number 52): the lowest order bit, a 1, is removed Similarly, division by any power of two 2 k may be
Midys theorem - Wikipedia The extended Midy's theorem[2] states that if the repeating portion of the decimal expansion of a p is divided into k -digit numbers, then their sum is a multiple of 10 k − 1 For example, has a period of 18
Decimal - Wikipedia Decimal fractions (sometimes called decimal numbers, especially in contexts involving explicit fractions) are the rational numbers that may be expressed as a fraction whose denominator is a power of ten [8]
