Answer 2

Keep subtracting. For example 100 divided by 2, you can subtract 2 from 100 leaving 98. subtract 2 from 98 leaves 96. Keep subtracting 2 until you reach 0 and you'll find you did 50 subtractions. so your answer is 50.

Answer 3

Make them jealous? You will have to clarify your question.

Additional answer. Thanks for the clarification. This is probably clearer in your text than I can make it here, but I will try. As an example, I will use 1,600,031 divided by 647:
''''''''''''' ________
647 / 1600031

Ignore the '''''''''''', which I added to put the bar over 1600031.
Divide 6, the first digit of 647, into 1, the first digit of 1600031. That cannot be done, so try again. This time, divide 6 into 16, the first two digits of 1600031. Since 2x6 is 12 and 3x6 is 18, 3 is too big, and we will try 2:

''''''''''''' ___2____
647 / 1600031

Multiply 2 times 647 = 1294, and write that under 1600:

''''''''''''' ___2____
647 / 1600031
''''''''''''' 1294

Once again, ignore the ''''''''''''' . Subtract 1294 from 1600 to get 360 and bring down the next digit, which is another 0:


''''''''''''' ___2____
647 / 1600031
''''''''''''' 1294
''''''''''''' ----------
'''''''''''''''' 3060

Now divide 6, the first digit of 647, into 30, the first two digits of 3060. Although 5x6 is exactly 30, multiplying 5 by 647 will give a result bigger than 3060. Try, 4, the next lower digit:

''''''''''''' ___24___
647 / 1600031
''''''''''''' 1294
''''''''''''' ----------
'''''''''''''''' 3060

Multiply 4x647 to get 2588 and write that under 3060:


''''''''''''' ___24___
647 / 1600031
''''''''''''' 1294
''''''''''''' ----------
'''''''''''''''' 3060
'''''''''''''''' 2588
''''''''''''' ------------

Subtract 2588 from 3060 to get 472 and bring down the next digit from 1600031, which is a 3:

''''''''''''' ___24___
647 / 1600031
''''''''''''' 1294
''''''''''''' ----------
'''''''''''''''' 3060
'''''''''''''''' 2588
''''''''''''' ------------
''''''''''''''''''''4723

Divide 6, the first digit of 647 into 47, the first two digits of 4723. Since 6x7 = 42, try 7:


''''''''''''' ___247__
647 / 1600031
''''''''''''' 1294
''''''''''''' ----------
'''''''''''''''' 3060
'''''''''''''''' 2588
''''''''''''' ------------
''''''''''''''''''''4723

Multiply 7x647 to get 4529, and write that under 4723:

''''''''''''' ___247__
647 / 1600031
''''''''''''' 1294
''''''''''''' ----------
'''''''''''''''' 3060
'''''''''''''''' 2588
''''''''''''' ------------
''''''''''''''''''''4723
''''''''''''''''''''4529
''''''''''''' ------------

Subtract 4529 from 4723 to get 194 and bring down 1, the last digit:


''''''''''''' ___247__
647 / 1600031
''''''''''''' 1294
''''''''''''' ----------
'''''''''''''''' 3060
'''''''''''''''' 2588
''''''''''''' ------------
''''''''''''''''''''4723
''''''''''''''''''''4529
''''''''''''' ------------
'''''''''''''''''''''''1941

Divide 6, the first digit of 647. into 19, the first two digits of 1941. Since 6x3 = 18, let's try 3:

''''''''''''' ___2473__
647 / 1600031
''''''''''''' 1294
''''''''''''' ----------
'''''''''''''''' 3060
'''''''''''''''' 2588
''''''''''''' ------------
''''''''''''''''''''4723
''''''''''''''''''''4529
''''''''''''' ------------
'''''''''''''''''''''''1941

Multiply 3x647 to get 1941. Write that under 1941, subtract, and you have completed the problem:

''''''''''''' ___24___
647 / 1600031
''''''''''''' 1294
''''''''''''' ----------
'''''''''''''''' 3060
'''''''''''''''' 2588
''''''''''''' ------------
''''''''''''''''''''4723
''''''''''''''''''''4529
''''''''''''' ------------
'''''''''''''''''''''''1941
'''''''''''''''''''''''1941
''''''''''''' ------------
'''''''''''''''''''''''''''' 0

If the last subtraction does not come out with a zero, the result of the last subtraction is reported as a 'remainder.' That (whew) is how you divide.

Answer 4

Use calculator if not Excel spreadsheet.

Answer 5

know all your multiplications
