Someone more versant will no doubt suggest a more concise solution:

<?php
$dvnd = 22;
$dvsr = array(1,2,3,5,7,11);

foreach ($dvsr as $k => $v) {
$result = $dvnd/$v;
if (($dvnd % $v) > 0) {
echo sprintf( "$dvnd/$v = %.4f<br>", $result );
} else {
echo sprintf( "$dvnd/$v = %d<br>", $result );
}
}
?>

produces:

22/1 = 22
22/2 = 11
22/3 = 7.3333
22/5 = 4.4000
22/7 = 3.1429
22/11 = 2

$result = 22/7;
