As imaginary numbers (square root is negative) are useful, is there any mathematical use for an imaginary number that, when multiplied by zero, gives a non-zero result?

“Imaginary numbers” aren’t actually imaginary. They got that name back when people didn’t realize they actually exist. The reality is that they are actual numbers and do actual numbers things.

Division by 0 is mathematically undefined. There is no definable number that you can use to do number things expressed by 1/0.
