Divide by a whole number
In dividing a decimal by a whole number, say, 22.63 divided by 4, we set the problem up as a usual division problem. So, 4, divided into 22.63. Next, we place the decimal point directly above the decimal point in the dividend, as you see here.

Next, we work out the problem as you would a normal division problem, as I have done here. And, in this problem I had to place in a couple of zeros in the dividend till the remainder was equal to zero.

And sometimes a remainder of zero is never obtained when dividing, such as in this problem here as the 4 and 5 will keep repeating.

In a situation like this, continue the division, and place in zeros, to 1 decimal place more than you need to round the answer to. So, if I want to round to the nearest thousandth, I would carry the division out to the nearest ten thousandth, and then rounded the answer off.

Here are some more examples of dividing decimals by whole numbers, with the division process and rounding off written off.

One note, if you want to check your answer, you can multiply your answer, the quotient, by the divisor. And this answer should equal the dividend in the original problem.
