Hii Surender
Try Below Code 
String invalidNumbers = '[^0-9]';  
String str = 'Auto - New Business - Count;Premium - 500';  
system.debug( 'Only numbers - ' + str.replaceAll( invalidNumbers, '' ) );

Hi Surender,

The below code will serve your purpose.

// string contains numbers
String str = 'Auto - New Business - Count;Premium - 500';

// extract digits only from strings
String numberOnly = str.replaceAll('[^0-9]', '');

// print the digitts
System.debug(numberOnly);
Please mark this as the correct answer for others.
Thanks in advance !!

Hi,

Please find the solution.

String notValidNumber= '[^0-9]';  
String str = 'Auto - New Business - Count;Premium - 500';  
system.debug( 'Only numbers - ' + str.replaceAll( notValidNumber, '' ) );  

or

String formattedStr = 'Auto - New Business - Count;Premium - 500';
String[] strArr = formattedStr.split('-');
  
system.debug('myNumber::'+strArr[3]);
