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

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.

For BigInt division, the result is the quotient of the two operands truncated towards zero, and the remainder is discarded. A RangeError is thrown if the divisor y is 0n.

var x = parseInt(455/10);
The parseInt() function parses a string and returns an integer.
The radix parameter is used to specify which numeral system to be used, for example, a radix of 16 (hexadecimal) indicates that the number in the string should be parsed from a hexadecimal number to a decimal number.
If the radix parameter is omitted, JavaScript assumes the following:
If the string begins with "0x", the radix is 16 (hexadecimal) If the string begins with "0", the radix is 8 (octal). This feature is deprecated If the string begins with any other value, the radix is 10 (decimal)

How to perform integer division and get the remainder in JavaScript?
The residual remainder is calculated when both operands are non-zero and finite. Here, (remainder= divisor - dividend * quotient), where the quotient is an integer with the same sign as the dividend x and is as close to 0 as possible.
