How to explain what a Turing Machine does

I need to explain what the following turing machine does:


The input tape is: 0110111000011BB

I know that the ouput is: BBCCCCCCCCCCC*B

And if tape is empty it will return: M

How do I explain what it does? just say something like: “it transforms the first two digits into ‘B'(or erase them) and the next ones into ‘C’ followed by a ‘*’ and a ‘B'”?

I am new at this. Thanks.
