he least significant digits can be calculated, because they remain fixed! Starting at 1!+2!+3!+4! = 33, the units digit will remain 3 indefinitely. The sum at 9! will have the fixed last two digits (10! ends with two 0s).

The most signigicant digits can be found in a similar way, pretty much done above, with 50! having the same leading digit as S. So
S = 3. something...3 x 10^64
