How can i replace a string with the required

Hi all i am having my data as follows

52201               1                   1         PPD1         111017111017   1111000020000003

Here i would like to replace the one with bold to 0000002 can any one help me. I used the following but i am unable to replace it

if (strBtchno1.StartsWith("5"))
{
    iBtchno = Convert.ToInt16(strBtchno1.Substring(87, 7));
    if (iBtchno > iBatchno)
    {
       iBtchno = iBtchno - 1;                      
       strBtchno1 = strBtchno1.Substring(0,87) + iBtchno.ToString() + strBtchno1.Substring(7,(strBtchno1.Length - 7));
     }                       
  }

string strBtchno1 = "52201               1                   1         PPD1         111017111017   1111000020000003";
int iBtchno = Convert.ToInt32(strBtchno1.Substring(strBtchno1.Length - 7));
iBtchno++;
strBtchno1 = strBtchno1.Substring(0, strBtchno1.Length - 7) + iBtchno.ToString("d7");

7 digits is an int, not a short!!!

And to format the number back with the padding you can use iBtchno.ToString("d7").
