实现921和999乘39个整数循环

我处于这样一种情况下,我需要实现除法921/39,并通过给出整数(循环39次),再次实现921。

$packagesCount = count($packages);      // = 39
$averageWeight = 921/$packagesCount;    // = 23.6153846154

foreach ($packages as $package) {
    $package['Weight'] = "<whole number>";
}

原因是,我需要给出API的整数,但总数应该是921。因此,我不能给出整数。

我想到的一个方法是:

$packagesCount = count($packages);      // = 39
$averageWeight = 921/$packagesCount;    // = 23.6153846154
$remainder = ceil($averageWeight);      // = 24 

foreach ($packages as $package) {
    $package['Weight'] = floor($averageWeight);

    if ($remainder > 0) {
        $package['Weight'] += 1;            
        $remainder -= 1;
    }
}

但是试着用 999 总重量不适用于这种方法;它最终给出的不是999 39 * 25 + 26 = 1001 .

对于999,我应该使用 39 * 25 + 24 = 999 但是如何呢?
