When it dont work
An easy solution is to move both decimal places (by the same amount of course) until there is no decimal places left.
eg.
.0045/.000046 is the same as 4500/46.
and then just proceed normally.

By the time you advance to the point of dividing decimals, you don't use remainders any more.
To multiply decimals, first ignore the decimal point.For example: 5.3 x 4.2 = 22.26 on a calculator.To manually reach the same answer:Multiply without the decimal point: 53 x 42 = 22265.3 is 1 decimal point4.2 is 1 decimalTotal is 2 decimal points, which makes the answer 22.26
In that you carry out exactly the same steps - AND you must determine the correct position of the decimal point.
The fundamental operations on whole numbers and decimals are addition, subtraction, division, and multiplication. However, multiplying and dividing decimals is a bit more complicated because you have to count decimal points to get an accurate answer.
it just means to brings the decimal up ^^
