long division

Let's see how it is done with:

• the number to be divided into is called the dividend
• The number which divides the other number is called the divisor

And here we go:

	4 ÷ 25 = 0 remainder 4	The first digit of the dividend(4) is divided by the divisor.
		The whole number result is placed at the top. Any remainders are ignored at this point.
	25 × 0 = 0	The answer from the first operation is multiplied by the divisor. The result is placed under the number divided into.
	4 − 0 = 4	Now we subtract the bottom number from the top number.
		Bring down the next digit of the dividend.
	42 ÷ 25 = 1 remainder 17	Divide this number by the divisor.
		The whole number result is placed at the top. Any remainders are ignored at this point.
	25 × 1 = 25	The answer from the above operation is multiplied by the divisor. The result is placed under the last number divided into.
	42 − 25 = 17	Now we subtract the bottom number from the top number.
		Bring down the next digit of the dividend.
	175 ÷ 25 = 7 remainder 0	Divide this number by the divisor.
		The whole number result is placed at the top. Any remainders are ignored at this point.
	25 × 7 = 175	The answer from the above operation is multiplied by the divisor. The result is placed under the number divided into.
	175 − 175 = 0	Now we subtract the bottom number from the top number.
		There are no more digits to bring down. The answer must be 17
