Dividing Decimals Section 1-4

Steps: 1.)Write the problem with a division bar. (The dividend is inside the bar.) 2.)Move the divisor's decimal the amount of spaces until it makes a whole number. 3.)Move the dividend the same amount of spaces as the divisor. If needed add a zero before you move an extra space that is not in the number.(This does not occur every time.) 4.)Bring up your decimal point to the top bar, where you put your quotient on top. 5.) Divide

Division ????? 1.2) 8.76 Quotient Divisor Dividend Steps:
8.76 ÷ 1.2 = ????? Divisor 1.2) 8.76 Dividend Steps: 1.)Write the problem with a division bar. (The dividend is inside the bar.)

Division ????? 1.2) 8.76 Quotient Divisor Dividend Steps:
2.)Move the divisor's decimal the amount of spaces until it makes a whole number. So, you would have to move 2 spaces.

Division ????? 12.) 8.76 Quotient Divisor Dividend Steps:
2.)Move the divisor's decimal the amount of spaces until it makes a whole number. So, you would have to move 2 spaces.

Division ????? 12.) 8.76 Quotient Divisor Dividend Steps:
time.) Dividend Steps: 3.)Move the dividend the same amount of spaces as the divisor. If needed add a zero because you move an extra space that is not in the number.(This does not occur every time.)

Division ????? 12.) 87.6 Quotient Divisor Dividend Steps:
time.) Dividend Steps: 3.)Move the dividend the same amount of spaces as the divisor. If needed add a zero because you move an extra space that is not in the number.(This does not occur every time.)

. 12 ) 87.6 Steps: 4.)Bring up your decimal point to the top bar, where you put your quotient on top.

Step 5 Divide Ask yourself….How many times will 12 go into 87? Well, I know that *12= 84 and *12 = 96, but that is too high. 7 . 12 ) 87.6 -84 3

Step 5 Divide Ask yourself….How many times will 12 go into 3? 7 3 . 12 ) 87.6 Well, I know that it’s zero times, so drop down the next number. -84 3 6 -36 Ask yourself….How many times will 12 go into 36? .
