82.3/2.9 = (82.3*10)/(2.9*10) = 823/29 =
(29*28+11)/ 29 = 28 + 11/29 = 28 + 0.38 = 28.38

I assume you aren't allowed to use a calculator. You have to get rid of the decimals when dividing
so you have to move the decimal in the 2.9 over one spot to the right to make it 29 and because you did so you have to do the same thing to the 82.3, move the decimal over one place to the right, then divide normally bringing your decimal point up above after the 3 in 823. Hope this makes sense to you. The answer is 28.4 (rounded out, actual is 28.37)

To make it easier for everyone, you multiply the entire equation by 10 to get rid of the decimals. You'll have 823/29. Then, you can use long division.

29 goes into 82 two times. 29*2=58. 82-58=24. 29 goes into 243 eight times. 29*8=232. So... your answer is 28 with a remainder of 11.

You do not have to divide anything because, when you think of it, 4/2 gives the same answer as 40/20 and so on.

Without a calculator, long division works...

2.9 divides into 82.3 twenty-eight times, with a remainder of 1.1

Moving the decimal point, 2.9 divides into 11 three times, with a remainder of 2.3

etc...then put it all together at the end.

First move the decimal back from each nuber to have 823 29.Second how many times 29 goes into 82.2 times so 82 minus 58 giving you 24 plus the 3 left over giving you 243.Last 29 times 8 giving you 232 so 243-232=giving you 28.11.

28 and 11/29

Move the decimal over the the right one time to both numbers and you will have 823/29. Simplify the faction and you will get 28 11/29

Pencil and paper for this one- I don't trust calculators since the time mine concluded 2/4 was 128.
I'll round up to 3 and down to 82 for simplicity.
82/3=27⅓
That should be close enough, however if a more specific answer is desired, ask and you shall receive.

I am going to humour you:

First get rid of the decimals:

82.3/2.9 = 823/29

Now you can perform long division:

..........28.37
29 | 823.000 (29 goes into 82? 2 times)
..........58 (=2*29)
-----------------
..........243 (29 goes into 243? 8 times)
..........232 (=8*29)
-----------------
............110 (29 goes into 110? 3 times)
..............87 (=3*29)
-----------------
..............230 (29 goes into 230? 7 times)
..............203 (=7*29)
-----------------
................270 (you can carry on here if you wish)
