Applying KNN Clustering based on user id

Dataset file : google drive link

Hello Community , I need help regarding how to apply KNN clustering on this use case.

I have a dataset consisting (27884 ROWS, 8933 Columns)

Here's a little preview of a dataset

user_iD	b1	b2	b3	b4	b5	b6	b7	b8	b9	b10	b11
1	1	7	2	3	8	0	4	0	6	0	5
2	7	8	1	2	4	6	5	9	10	3	0
3	0	0	0	0	1	5	2	3	4	0	6
4	1	7	2	3	8	0	5		6	0	4
5	0	4	7	0	6	1	5	3	0	0	2
6	1	0	2	3	0	5	4	0	0	6	7

Here the column userid represents: STUDENTS and columns b1-b11: They represent Book Chapters and the sequence of each student that which chapter he/she studied first then second then third and so on. the 0 entry tells that the student did not study that particular chapter.

This is just a small preview of a big dataset. There are a total of 27884 users and 8932 Chapters stated as (b1--b8932)

I need to find a similar pattern and thus need to apply KNN clustering, how do I do that?
