I just finished creating a tutorial on how to add different types of columns in a WordPress template. The first example from my tutorial sounds exactly like what you need.

<?php
    // Custom loop that adds a clearing class to the first item in each row
    $args = array('numberposts' => -1, 'order' => 'ASC' ); //For this example I am setting the arguments to return all posts in reverse chronological order. Odds are this will be a different query for your project
    $allposts = get_posts($args);
    $numCol = 2; // Set number of columns
 
    // Start Counter
    $counter = 0;
    foreach ($allposts as $post) {
        $content = '<div class="columns-'.$numCol.($counter % $numCol == 0 ? ' first' : '').'">'; // Add class to first column
        $content .= '<h3><a href="'.$post->guid.'">'.$post->post_title.'</a></h3>';
        $content .= $post->post_content;
        $content .= '</div>';
        echo $content;
        $counter ++;
    }
?>
 
<style type="text/css">
    /* Added styles here for the demo, but ideally you would put this in a stylesheet.*/
    .columns-2 {
        float:left;
        width:45%;
        margin-left:10%;
    }
    .first {
        clear:both;
        margin-left:0;
    }
</style>

The above code uses the modulus operator like @alchymyth suggests in order to add a “clearing” class every X posts in a loop. CSS is then used to float the posts into columns and clear at the beginning of each row.
