876 divided by 21. You can use your knowledge of the base 10 system to say: 21X10=210(too small)

21X20=420(still too small)

21X30=630(let me subtract 876-630=246, I'm getting close)

21X40=840 and when I subtract I get a remainder of 36. I can make 1 more group of 21. 36-21=15. So my answer is 41 with a remainder of 15.

You can use multiples of 100,100, etc. for larger numbers.

Long division

Yes, except at odd multiples of pi/2 radians, where the cosine is zero so that the division is not defined.

"Quotient" implies that there is some sort of division going on. I don't see any evidence of that.

I hope that by multiples you mean multiplication.So, take a variable x, then multiply it by ... 2, for example. You now have 2x. Now, divide 2x by two, you have x. When you think about it, division and multiplication don't seem to be direct opposites of each other (like + and -), but if you think more about it, you'll see they are. Proof: 10+2-2=10 and 10x2:2=10

The answer to the division is a number (8) that can be added to itself to make 16. The answer to the square root is a number (-4 or +4) that can be multiplied by itself to make 16.
