Work Step by Step

Subtract the numbers vertically. Make sure that the numbers are aligned according to place value. Subtract starting with the rightmost column. Since $5$ is greater than $0$, regrouping must be done, The following must be done to the minuend: Borrow one from $2$. Change $2$ to $1$. This will make the units digit of the minuend $(0)$ become $10$. Then borrow $1$ from $10$. Change $10$ to $9$ Repeat the previous step until you reach the last decimal place. Then, perform the subtraction. (Refer to the attached image below for the actual subtraction.)
