Try again leaving spaces around the / .

When dealing with non-integer numbers I'd recommend to use bc instead of expr.
Code:
$ E=1296863.27001857757568359375
$ S=21997
$ F=$(echo "$E / $S" |bc)
$ echo $F
58
$ F=$(echo "scale=20; $E / $S" |bc)
$ echo $F

You can use
Integer
Code:
F=$(($E/$S))

Non integer
Code:
F=$(echo $E $S | awk '{print $1/$2}')
