Xiao Dong read a 420-page book. He read 26 pages a day, and after 13 days, there were still pages left. The calculation process was as follows: The total number of pages he read in 13 days was 26 * 13 = 336 pages. The total number of pages in this book is 420, so the total number of pages needed to read the whole book is 420. Therefore, the number of pages Little Dong needed to finish reading the book in 13 days was 336 pages/13 days = 26 pages/day. Because Xiao Dong read 26 pages every day, the total number of pages he read every day was 26 + 26 = 52. Therefore, the number of pages Little Dong needed to finish reading the book in 13 days was 52 pages/13 days = 4 pages/day. Because Xiao Dong read four pages a day, the remaining pages were 420 - 4 * 13 = 420 - 52 = 368. Therefore, Xiao Dong still had 368 pages to read.
