19 divided by 5 would equal 3 and 4/5, or 3.8 as a decimal, because 19 goes into 5- 3 times and there is a remainder of 4.
So, in long division, 19 ÷ 5= 3.8, 3 and 4/8, or 3 remainder 4. All if those are correct, though I suggest you use 3.8. Oh, and btw, I'm pretty sure this isn't high school level. Anyways, hope this helps you.
