Match match = Regex.Match(string, @"Transfer: [0-9.]+ MB$");
if (match.Success)
   var dataLeft = match.Groups[1].Value;

Using regular expression for that seems overkill. Just look for the string "Transfer: " and then look for the following " MB", and get what's between:

int start = str.IndexOf("Transfer: ") + 10;
int end = str.IndexOf(" MB", start);
string mb = str.Substring(start, end - start);

var rx = new Regex(@"Transfer: ([0-9]+(?:\.[0-9]+)?)");
var result = rx.Match(html).Groups[1].Value;

BUT you shouldn't parse html with Regex. I'm "anchoring" the regex to the "Transfer: " string.

Match m = Regex.Match(string, @"Transfer: ([0-9.]+) MB");
if (m.Success)
{
    string remaining = m.Groups[1].Value
}

That should do it.
