title: How to divide big numbers?
body: <p>I have a big number (integer, unsigned) stored in 2 variables (as you can see, the high and low part of number):</p>
  
  <pre><code>unsigned long long int high;
  unsigned long long int low;
  </code></pre>
  
  <p>I know how to add or subtract some other that-kind of variable.</p>
  
  <p>But I need to divide that-kind of numbers. How to do it? I know, I can subtract N times, but, maybe, there are more better solutions. ;-)</p>
