The division is one of the four basic operations of arithmetic, how numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication. At an elementary level, the division of two natural numbers is, among other possible interpretations, the process of calculating the number of times one number is contained within another. This number of times is not always an integer (a number obtained using the other arithmetic operations on the natural numbers). Instead, the division with a remainder or Euclidean division of two natural numbers provides an integer quotient, which is the number of times the second number is completely contained in the first number, and a remainder, which is the part of the first number that remains when in the course of computing the quotient, no further full chunk of the size of the second number can be allocated.
