Select specific rows in dataset

Hello everyone, I have a dataset of 3174 rows and 2041 columns. In the 2041 column of this dataset there are numbers "0", "1", and "2". These numbers are the classification of something. How can I obtain all rows with "0" in column 2041? I will be grateful if you could help me.
