You need to tip the pot upside down and tap on the bottom until the soil and plant separate from the pot. Then gently shake off the soil until the roots are exposed. try and separate the roots from one another as best as possible. No guaranties to this because what you are needing to do will cause major stress to the plant. be as quick as possible without damaging the roots as much as possible. have 2 buckets with fresh soil and a bit of h20 ready when you seperate
