"Regrouping" is a more modern word for "borrowing".
When subtracting with decimals, if you are trying to subtract a larger digit from a smaller digit, you "regroup" the next digit to the left by taking one away from it and adding 10 to the number you are subtracting from.
Example
84
- 19
_____
You can't subtract 9 from 4, so you take one away from the next digit over (the 8) and add 10 to the 4.
14 - 9 is 5 in the ones digits
7 - 1 is 6 in the tens digits
Now if you are subtracting mixed numbers, the regrouping process is essentially the same, except that instead of always regrouping by tens, we regroup by the denominator size.
8 1/5
- 3 3/5
______
We can't subtract 3/5 from 1/5, so we regroup one unit from the 8 into 5 fifths.
7 6/5
-3 3/5
_______
4 3/5
It is very easy when you get some practice doing it.

What regroup mean in subtraction?
Regrouping in subtraction means that if you can't subtract because the digit on the bottom has a greater value than the digit on the top (such as 3-6), you have to "regroup" and subtract on from the top digit to the left of the digits your working with and then add a ten to the top digit your working with. Finally, you subtract. (645-9=630+15-9) Hope that makes sense!

What is the difference between subtracting with regrouping in whole numbers and subraction with regrouping in fractions?
We look at the signs of numbers when we need to combine them. We subtract only if numbers have different signs, otherwise we add them. So that, if we have in an expression several positive and negative numbers, we prefer to group numbers with the same sign and add them in order to subtract just once. While with fractions we like to group fractions with the same denominator first, and after that we can combine all fractions by finding their LCD.
