There is only one 8-digit number, down the center column. There are only two 5-digit numbers (3rd and 10th rows) and the 8-digit number helps positioning them. The two 10-digit numbers flank the 8-digit number (and also imply two 3-digit horizontal numbers) and the 5-digit numbers help choosing where. The four 9-digit numbers go in the middle rows; having the 8-digit and 10-digit numbers make this easy. Having the 9-digit numbers in place help placing two 6-digit numbers in the 5th and 11th column, and this takes care of the whole center portion. Finally, you only require very little "try-and-test" for locating the 6-digit numbers in the first and last rows, which makes the rest rather quick. A good puzzle!
