If you divide a five digit number by a one digit number, what is the largest possible remainder you can get

Answer is 8

Step-by-step explanation:

Since we need to find out largest possible  remainder which can be obtained by  taking largest one digit number which is 9 . now we find any five digit number say 99998 , we cannot take 99999 because  its divisible  by 9 and gives remainder 0 .

therefore dividing 99998 by  9 gives remainder  8 which is largest remainder obtained by dividing by 9 .
