Division is one among the four basic operations of arithmetic, the ways in which numbers are combined to make new numbers. the opposite operations are addition, subtraction, and multiplication.
At an elementary level the division of two natural numbers is, among other possible interpretations, the method of calculating the number of times one number is contained within another.7 This number of times needn't be an integer. for instance , if 20 apples are divided evenly between 4 people, everyone receives 5 apples (see picture).
The division with remainder or Euclidean division of two natural numbers provides an integer quotient, which is that the number of times the second number is completely contained in the first number, and a remainder, which is that the part of the first number that remains, when within the course of computing the quotient, no further full chunk of the dimensions of the second number can be allocated. for instance , if 21 apples are divided between 4 people, everyone receives 5 apples again, and 1 apple remains.
For division to always yield one number instead of a quotient plus a remainder, the natural numbers must be extended to rational numbers or real numbers.
