Turing machine that converts decimal to binary I'm a beginner in Turing machine computation and want to design two TMs; one that converts decimal number to binary, and other one that converts binary to decimal.  

Could anyone help me design these Turing machines? How can I start?

Thanks.
You can play around and try your ideas with this simulator.  

Under examples, you can find decimal to binary converter. Furthermore, you can learn about TMs in tutorial section.
