We start by simplifying the fraction algebraically:

Notice that both numerator and denominator are divisible by small factors. However, since this is specific, we compute directly:

\[
3628800 \div 1440 = ?
\]

Break 1440 into prime factors:
\[
1440 = 144 \cdot 10 = (12^2) \cdot (2 \cdot 5) = (2^2 \cdot 3)^2 \cdot 2 \cdot 5 = 2^4 \cdot 3^2 \cdot 2 \cdot 5 = 2^5 \cdot 3^2 \cdot 5
\]

Now factor 3,628,800:

It turns out that
\[
3628800 = 720 \cdot 5040
\]
and
\[
720 \cdot 1440 = 3628800
\]

But for direct computation:

Using calculator-level precision or step division:
\[
3628800 \div 1440 = 2520
