# Integer Division and Remainders

**Integer division** is a common mathematical operation that we often use in daily life, sometimes without even realizing it.

Take, for instance, the scenario where you have `16`

candies and want to divide them equally among `3`

friends. Each friend would get `5`

candies, with **one** candy left over, since `16 = 5 * 3 + 1`

. We say that the result of the **integer division** of `16`

by `3`

is `5`

, and the **remainder** of this division is `1`

.

In R, these operations are performed using:

`%/%`

for integer division;`%%`

for the remainder of a division.

Here is how we can calculate the given example in R:

`# Number of candies for each friend 16 %/% 3 # Number of candies remaining 16 %% 3`

Task

For the following exercises:

- Compute how many complete days there are in
`435`

hours. - Determine how many hours would be left over.

Keep in mind that a day is comprised of 24 hours.

`%/%`

for integer division;`%%`

for the remainder of a division.
