I believe this should work:

storing the output got into variables is upto you.

Code:
 
 
cat input_file
e1000g112001
e1000g0
nge11101
nge3
 
$head -1 rem | sed 's/\(.*[a-z]\)\(.*\)/\1/'
e1000g

$head -1 rem | sed 's/\(.*[a-z]\)\(.*\)/\2/'
112001
 
$head -4 rem | sed 's/\(.*[a-z]\)\(.*\)/\1/'
e1000g
e1000g
nge
nge


$head -4 rem | sed 's/\(.*[a-z]\)\(.*\)/\2/'
112001
0

imaxdiv

div(3C) 																   div(3C)

NAME

       div(), ldiv(), lldiv(), imaxdiv() - integer division and remainder

SYNOPSIS

DESCRIPTION

       Computes the quotient and remainder of the division of the numerator
		      numer  by  the  denominator  denom.  If the division is inexact, the sign of the resulting quotient is that of the algebraic
		      quotient, and the magnitude of the resulting quotient is the largest integer less than the magnitude of the  algebraic  quo-
		      tient.   If the result can be represented, the result is returned in a structure of type (defined in having members quot and
		      rem for the quotient and remainder respectively.	Both members have type and values such that quot denom rem numer.  If  the
		      result cannot be represented, the behavior is undefined.

       Similar to     except  that  the arguments each have type and the result is returned in a structure of type (defined in having members quot
		      and rem for the quotient and remainder respectively.

       Similar to     except  that  the arguments each have type and the result is returned in a structure of type (defined in having members quot

WARNINGS

       Behavior is undefined if denom is zero.
