iOS Swift Basics Swift Operators Working With Operators

I am unsure of how to write out the result, and how to write the code to get a remainder.

Could someone help me figure out how to write the remainder code to get the result? Also for step 2 i know that I am supposed to use == but not sure how to format it.

operators.swift 
// Enter your code below
let value = 200
let divisor = 5

let someOperation = 20 + 400 % 10 / 2 - 15
let anotherOperation = 52 * 27 % 200 / 2 + 5

// Task 1 - Enter your code below
let result = "The % of \(value) and \(divisor)

// Task 2 - Enter your code below
let isPerfectMultiple = "0 == \(result)"

The challenge doesn't want you to specify any text. It wants the calculation using the variables provided. The first step uses the modulo operator:

let result = value % divisor

This is the remainder for value divided by divisor. The second step wants a boolean value that determines if the result is a perfect multiple. For this to be true result would equal zero

let isPerfectMultiple = result == 0

THank you! I was definitely over thinking it.
