divide number with decimals javascript

Question

how can I divide number (money) to x number equally the number could be with one or two decimal or without it

such as 1000 or 100.2 or

Answer 1

If anyone is looking for a randomly distributed vanilla JS solution here is mine:

function fairDivision(resolution, numerator, denominator) {
    // preserves numerator(n) integrity when dividing into denominator(d) bins
    // remainders are randomly distributed into sequential bins 
    // resolution is number of significant digits after decimal
    // (-'ve resolution for insignificant digits before decimal).
    const n = numerator * Math.pow(10, resolution);
    const remainder = n % denominator;
    const base = (n - remainder) / denominator;  
    const offset = Math.floor(Math.random()*denominator); // index of first 'round-up' bin

    let arr = []
    let low= (offset + remainder) % denominator;

    let a; let b; let c = (low < offset); //logical units
    for (let i=0; i < denominator; i++) {
        a = (i < low);
        b = (i >= offset);
        if ((a && b) || (a && c) || (b && c)) {
            arr.push(base +1)
        } else{
            arr.push(base)
        }
        arr[i] = arr[i] / Math.pow(10, resolution);
    }
    return arr;
}
