Php 7.1, 166163 bytes

Via CLI providing the number as an argument:

<?foreach(str_split($argv[1])as$k=>$d)$a[]=array_fill(0,$s+=$k+1,array_fill(0,$s,$d));foreach(array_replace_recursive(...array_reverse($a))as$v)echo join('',$v)."\n";

Not so golfed:

$n = 123;

foreach(str_split($n) as $k => $d) {
    $s += $k + 1;
    $a[] = array_fill(0, $s, array_fill(0, $s, $d));
}

foreach(array_replace_recursive(...array_reverse($a)) as $v)
    echo implode('', $v) . "\n";

Output:

122333
222333
222333
333333
333333
333333

Method:

Basically build multi-dimensional array squares consisting of the digit, and then superimpose all of them (array_replace_recursive).

(Yes, I know this is embarrassingly long.)
