For some number y and some divisor x compute the quotient (quotient)[1] and remainder (remainder) as:
const quotient = Math.floor(y/x);
const remainder = y % x;
Example:
const quotient = Math.floor(13/3); // => 4 => the times 3 fits into 13
const remainder = 13 % 3; // => 1
[1] The integer number resulting from the division of one number by another

Instead, you achieve floor division with Math.floor(a / b) — but the distinction between floor and truncate matters more than beginners expect, especially with negative numbers.

I'm no expert in bitwise operators, but here's another way to get the whole number:
var num = ~~(a / b);
This will work properly for negative numbers as well, while Math.floor() will round in the wrong direction.
This seems correct as well:
var num = (a / b) >> 0;
Note: Only use ~~ as a substitution for Math.trunc() when you are confident that the range of input falls within the range of 32-bit integers.
What is floor division?
Note that when dealing with negative ... negative infinity, which makes it different from simply truncating the decimal part of the result. Python: Python uses the // operator for floor division. result = 7 // 2 # result is 3 negative_result = -7 // 2 # negative_result is -4 · JavaScript: JavaScript ... More on designgurus.io
