Fine! To end this nonsense once and for all!

1. It's easier if you move 312 two decimal places left, so it becomes 31, 200

31, 200 / 50 = 624

Now you gotta move it back two decimal places right, to balance it out.

624 / 100 = 6.24

2. Let's break this up to make it easier to type:

2000 x 3 = 6000

100 x 3 =  300

75 x 3 =  225

6000 + 300 + 225 = 6525

3. Again, move the number one decimal place to the left to make it easier to calculate: 199870 / 15 = 13258

Now you must move the answer one decimal place to the right to balance it out:

13258 / 10 = 1325.8

4. Let's break this up (again...):

100 x 40 = 4000

32 x 40 = 1280

4000 + 1280 = 5280

5. Again, just move it two decimal spaces:

6500 / 25 = 260

Now move it back two decimal spaces:

260 / 100 = 2.6

6. Break it up:

60 x 4 = 240

7 x 4 = 28

240 + 28 = 268

Is thou highness satisfied?
