Dividing decimals by whole numbers involves a few simple steps: you divide as if the decimal weren't there, then place the decimal point in the quotient directly above its position in the dividend. For instance, dividing 6.4 by 2: think of it as 64 divided by 2, which is 32, then place the decimal, getting 3.2. What specific problems are you working on? I’d be happy to help walk through them with you or explore more examples together!
