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

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.

Integer Division and Finding the Remainder in JavaScript
September 6, 2023 - The modulo operation finds the remainder after division of one number by another. In JavaScript, this operation is performed using the % operator. For example, if we divide 10 by 3, the quotient is 3 and the remainder is 1.

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)

Make one of those numbers a float.
737/parseFloat(1070)
or a bit faster:
737*1.0/1070
convert to 2 decimal places
Math.round(737 * 100.0 / 1070) / 100
2 of 6
23
(737/1070).toFixed(2); rounds the result to 2 decimals and returns it as a string. In this case the rounded result is 0.69 by the way, not 0.68. If you need a real float rounded to 2 decimals from your division, use parseFloat((737/1070).toFixed(2))
