Integer division is a mathematical operation where one integer is divided by another, resulting in a whole number. For example, if you divide 8 by 3, the result is 2 because 3 goes into 8 two times, with a remainder of 2. In integer division, we only care about the whole number part of the answer, ignoring any fractions or decimals. This type of division is commonly used in programming and computer science, where it helps in tasks like counting items or distributing resources evenly. For instance, if you have 10 candies and want to share them among 4 friends, each friend would get 2 candies, and there would be 2 candies left over.
