When dividing decimals what must you do if there is a decimal in the divisor?
When dividing decimals, if there is a decimal in the divisor, you should move the decimal point in the divisor to the right until it becomes a whole number. You must then move the decimal point in the dividend the same number of places to the right. Once both numbers are adjusted, you can proceed with the division as usual.
Must a decimal divisor and a decimal dividend have the same number of decimal places?
No.
When dividing decimals the divisor must always be a?
The divisor must always be a whole number. If it is not already, then you must multiply both the the divisor and dividend by ten until the divisor is no longer a decimal. For example, let's say you have to divide 1.0/0.5 . The divisor in this case would be 0.5 . To multiply by ten, simply move the decimal over to the right one space. That would leave you with 5.0, but since you have to do it on both sides, the final expression would look like this: 10/5 .
Why do you move the decimal to divide a decimal by a decimal?
To move the decimal you must move the decimal in the divisor all the way to the right to make it a whole number. Then in the dividend, you move that decimal to the right the same amount of spaces you did in the divisor.
How do you know what power of 10 to multiply a divisor and dividend by when dividing by a decimal?
You do not need to, but if you must do the following: if the divisor has n digits after the decimal point then multiply by 10n.
How is dividing a decimal by a whole number different than dividing 2 decimals?
Unlike dividing by a whole number, dividing buy a decimal number cannot be done directly - the divisor must first be converted to a whole number (and then the division can be done). The easiest way to do this conversion is to keep multiplying the divisor by 10 until a whole number is obtained; however, whatever is done to the divisor must also be done to the dividend, so by whatever the divisor is multiplied, the dividend must also be multiplied.
Must a decimal divisor and a decimal dividend have the same number of decimal places?
No.

Must a decimal divisor and a decimal dividend have the same number of decimal places in order to have a whole-number quotient?
No.
How do you know what power of 10 to multiply a divisor and dividend by when dividing by a decimal?
You do not need to, but if you must do the following: if the divisor has n digits after the decimal point then multiply by 10n.
How is dividing decimals similar to dividing whole numbers?
In that you carry out exactly the same steps - AND you must determine the correct position of the decimal point.

How do you divide 0.5 by1.41?
Make the divisor (1.41) a whole number and then divide normally. To make the divisor a whole number, the easiest way is to keep multiplying it by 10 until it becomes a whole number; but remember, division is just like a fraction - whatever you do to the denominator (bottom) you must also do to the numerator (top) - so whatever you do to the divisor (the number by which you are dividing) you must do to the dividend (the number into which you are dividing): 0.5 ÷ 1.41 = 50 ÷ 141 (multiply both by 100) = 50/141 ≈ 0.3546
How do you do division with remainder?
To perform division with a remainder, divide the dividend (the number being divided) by the divisor (the number you are dividing by) to find the quotient (the whole number result). Multiply the quotient by the divisor, and then subtract this product from the original dividend to find the remainder. The final result can be expressed as: Dividend = (Divisor × Quotient) + Remainder. The remainder must always be less than the divisor.
What is the purpose of adding zeros to the dividend when dividing?
As you divide and increase the number of decimal places, each zero is a holder of the decimal place. It must be used to take the level of accuracy of the answer to a decimal fraction that is 10 times as small as the previous decimal fraction.
Why do I get a repeating decimal when I divide?
When you get a repeating decimal when dividing, it means that the decimal representation of the quotient has a repeating pattern of digits. This occurs when the divisor (the number you're dividing by) is not a factor of 10, leading to a situation where the division process does not result in a clean, terminating decimal. The repeating decimal is a way to represent the fraction that results from the division in a concise form.
