Abacus calculation of the Zu Chongzhi approximation of pi

Some time ago I did a small clip showing how to calculate the so known chineese classical pi approximation fraction 355/113 with a mechanical calculator. This time I repeat this calculation with an abacus. Notice that this abacus does have a small number of columns, so I've had to change a bit the way the division is done in order to be able to fit the maximum nomber of digits of the result and the partial remainders.
