You need a custom walker to do that, an modified version of this one answered by toscho, just paste this class in your functions.php

class Description_Walker extends Walker_Nav_Menu
{
    function start_el(&$output, $item, $depth, $args)
    {
        $classes = empty($item->classes) ? array () : (array) $item->classes;
        $class_names = join(' ', apply_filters( 'nav_menu_css_class', array_filter( $classes ), $item ) );
        !empty ( $class_names ) and $class_names = ' class="'. esc_attr( $class_names ) . '"';
        $output .= "<div id='menu-item-$item->ID' $class_names>";
        $attributes  = '';
        !empty( $item->attr_title ) and $attributes .= ' title="'  . esc_attr( $item->attr_title ) .'"';
        !empty( $item->target ) and $attributes .= ' target="' . esc_attr( $item->target     ) .'"';
        !empty( $item->xfn ) and $attributes .= ' rel="'    . esc_attr( $item->xfn        ) .'"';
        !empty( $item->url ) and $attributes .= ' href="'   . esc_attr( $item->url        ) .'"';
        $title = apply_filters( 'the_title', $item->title, $item->ID );
        $item_output = $args->before
        . "<a $attributes>"
        . $args->link_before
        . $title
        . '</a></div>'
        . $args->link_after
        . $args->after;
        $output .= apply_filters( 'walker_nav_menu_start_el', $item_output, $item, $depth, $args );
    }
}

call wp_nav_menu in header.php like following

wp_nav_menu(
    array (
        'menu' => 'main-menu',
        'container' => 'div', // parent container 
        'container_id' => 'my_nav', //parent container ID
        'depth' => 1,
        'items_wrap' => '%3$s', // removes ul
    'walker' => new Description_Walker // custom walker to replace li with div
    )
);
