To divide the network 192.168.10.0 into at least three subnets, you need a subnet mask that provides enough bits for three subnets. That means you require a mask with at least 11 bits (2^11 - 2 = 2046 addresses), which corresponds to a /8 mask. So use a /8 subnet mask.
It depends on the number of clients per subnet, but a common choice is 255.255.255.192, which provides around 62 IP addresses per subnet.
