title: Divide operation using increment, loop, assign, zero
body: <p>We're only allowed to use the following operations:</p>
  
  <p><code>incr(x)</code> - Once this function is called it will assign x + 1 to x</p>
  
  <p><code>assign(x, y)</code> - This function will assign the value of y to x (x = y)</p>
  
  <p><code>zero(x)</code> - This function will assign 0 to x (x = 0)</p>
  
  <p><code>loop X { }</code> - operations written within brackets will be executed X times</p>
  
  <p>How can I implement divide operation?</p>
