High Quality Content by WIKIPEDIA articles! In arithmetic, the galley method, also known as the batello or the scratch method, was the most widely used method of division in use prior to 1600. The names galea and batello refer to a boat which the outline of the work was thought to resemble. An earlier version of this method was used as early as 825 by Al-Khwarizmi. The Galley method is thought to be Hindu in origin and is most effective when used on a sand abacus. The galley method writes few figures than long division, and results in interesting shapes and pictures as it expands both above and below the initial lines. It was the preferred method of division for 17 centuries longer than long division's 4 centuries.
