title: MIPS: How do parse out digits of a number? Basic question but yet hard
body: <p>I am currently learing MIPS for a class and wrote the below sample code.</p>
  
  <pre><code># UNTITLED PROGRAM
  
  .data   # Data declaration section
  
  .text
  
         main:      # Start of code section
  
                 li $t1, 72
             move $a0, $t1
             li $v0,1
  
         exit:
                li $v0, 10
                syscall
  
  # END OF PROGRAM
  </code></pre>
  
  <p>As shown the value of '72' is stored in register $t1.  Now, how do I parse out the '7' and '2' out?</p>
