Dividend = quotient multiplication and division. If there is a 0 at the end of the quotient, then the product of quotient multiplication and division (dividend) must have a 0 at the end, which contradicts the statement that there is no 0 at the end of dividend. So this sentence is right. I adjusted it three times, hoping it will help you!

I didn't learn fractional division in grade three, so this sentence is wrong after learning fractional division. Hehe, the questioner is not rigorous!
