675 minus the decimals equals 674. It was equivalent to moving forward a few digits in a novel to get a number that was several times the original number. It could be obtained by moving the decimal point a few digits and then multiplying or dividing. For example, moving the decimal point to the left by one digit would give 6741, and then multiplying 6741 by 10 would give 6741. Therefore, moving the decimal point forward by two places to get 674 is equivalent to moving the novel forward by two places to get 10 times the original number.

It takes 2202 digits to arrange the page number of a novel. How many pages does this book have?

Assuming that the book has $n$pages, then the page number needs to contain $n$numbers, each number representing a page number. Since the page number needs to be numbered, the total number of digits of the page number must be the power of $2$, which is $2k $, where $k$represents the number of digits of the page number. According to the question, the page number needs to use $2202$numbers, so the value of $k$should be a factor of $2202$, which means that $k$can be $1247142872144288 $. For any $k$, you can use the Enumeration Method to calculate how many pages you need to use $2k $numbers. For example, when $k=1$, there is $n=2202= 2 ^4&times 72$, so the book has a total of $2202+72=2274$pages. When $k=2$, there is $n= 2 ^7 times 144$, so this book has a total of $2 ^7 times 144+144=25108$pages. When $k=4$, there is $n= 2 ^14 times 288$, so this book has a total of $2 ^14 times 288+288=32064$pages. When $k=7$, there is $n= 2 ^28&times72 $, so this book has a total of $2 ^28&times72 +72=35904$pages. When $k=14$, there is $n= 2 ^44 times 288$, so this book has a total of $2 ^44 times 288+288=46608$pages. When $k=28$, there is $n= 2 ^72> times 144$, so the book has a total of $2 ^72> times 144+144=29472$pages. When $k=72$, there is $n= 2 ^144 times 288$, so this book has a total of $2 ^144 times 288+288=331728$pages. Therefore, it can be concluded that this book has a total of $2274+32064+46608+29472+33172+46832+35904+46608+29472+35904+25108+2202=298768$pages.
