divmod

Returns an array consisting of the quotient and remainder of the given numbers.

• Use Math.floor() to get the quotient of the division x / y.
• Use the modulo operator (%) to get the remainder of the division x / y.

const divmod = (x, y) => [Math.floor(x / y), x % y];

divmod(8, 3); // [2, 2]
divmod(3, 8); // [0, 3]
divmod(5, 5); // [1, 0]
