title: Regular expression to replace specific numbers to space
body: <p>Given:</p>
  <pre><code>a = 0145067168
  b = 0245067167
  c = 0345067166
  d = 0445067165
  e = 0545067184
  
  z = 2545067168
  </code></pre>
  <p>How do I remove leading indicators <strong>(&quot;01&quot;, &quot;02&quot;, &quot;03&quot;,&quot;04&quot;,&quot;05&quot;)</strong>, using regular expression</p>
  <p>This is the output I'm expecting:</p>
  <pre><code>45067168
  45067167
  45067166
  45067165
  45067184
  
  2545067168
  </code></pre>
  <p>Any help would be great thanks.</p>
