The 'Galley' method of division was probably the most widely used method of division prior to the 1600s. It is called 'Galley' because, when completed, a division looks a bit like a galley (boat).

The Galley method is thought to be Hindu in origin and an early version of this method was known to be used in the ninth century by a Persian called Al-Khowarizmi. It is still taught in parts of North Africa and the Middle East today.

This is how you could work out $65284$ divided by $594$ using the Galley method:

Can you see the two numbers I started with?

The calculation tells me that $ 625284 \div 594 = 109$
remainder $538$.

Can you see the answer and the remainder?

Here's another division done using the Galley method:

What is the answer to this division?

Here are two video clips of divisions using Galley
arithmetic:

If you are struggling to see what
is happening, try the division using your own method and see if you
can recognise numbers that are appearing in the galley method that
are also in your own recording. If you need further guidance, there
is a division, showing each of the main steps and some explanation,
in the
hints section of this problem.

Why does the method work?

How does this method compare with our modern methods of
