<?php

// Build the query
$the_query = new WP_Query( array(
    'post_parent'    => get_the_ID(),
    'post_type'      => 'page',
    'order'          => 'ASC',
    'orderby'        => 'menu_order',
    'posts_per_page' => - 1,
    'post_status'    => 'publish'
) );

// How we can divide the row in columns
$count     = count( $childrens->posts );
$divider   = max_int_divider ( $count, 4 );  // Set 4 as the maximum number of columns
$cols      = ( $count && $divider ) ? (int)12/$divider : 12; // Columns width for the grid classes (1-12)
// You can check more conditions, like ($count > 1 && $divider == 1) and do something
