Dividing by decimal is different from dividing by whole number as you have to multiply by a number to remove the decimal.
The difference is that all whole numbers are decimal numbers, but not all decimal numbers are whole numbers. For example a whole number such as 1 is a decimal number but a decimal number such as 1.5 is not a whole number.
A decimal rational number can be expressed as a fraction A decimal irrational number can not be expressed as a fraction

When you are dividing a decimal by a whole number you have to bring up the decimal. For example, 36.4 divided by 2, you would take the decimal that is between the 6 and the 4 in 36.4 and you bring it up. Then you divide like you normally would.
