8. (10 points) Adding, subtracting, multiplying, or dividing a number by a one-digit number (0 is not a one-digit number) is considered one operation. For example, 53 can be transformed into 1 through three operations: adding 3, dividing by 7, and dividing by 8. How many operations at least are required to transform 2014 into 1?
A. 4
B. 5
C. 6
D. 7
【Solution】Solution: The first operation forms a multiple of the largest divisor 9, $2014+2=2016$.
The second step division $2016 \div 9=224$.
Then, since 224 is a multiple of 8, the third step $224 \div 8=28$.
The fourth step $28 \div 7=4$.
The fifth step $4 \div 4=1$.
Therefore, the answer is: $B$.
