Duplicate Rows Based On SUM Of Cell Values

I have a number of rows that I want to have duplicated X number of times (and altered) where X is found by looking at certain cells within each row.

There are four numbers in each row, and I want to split them up into multiple rows each with three zeros and one one.

I would like to convert data from this:

Name W X Y Z
John 1 0 0 0
Doug 0 0 1 0
Karl 3 0 1 0
Mike 0 1 1 2
etc.

...to this:

Name W X Y Z
John 1 0 0 0
Doug 0 0 1 0
Karl 1 0 0 0
Karl 1 0 0 0
Karl 1 0 0 0
Karl 0 0 1 0
Mike 0 1 0 0
Mike 0 0 1 0
Mike 0 0 0 1
Mike 0 0 0 1
etc.

You can see that the W, X, Y, and Z columns from the four new Mike rows sum to equal the values in the original Mike row (0, 1, 1, 2), but everything has been split so that each row just has a single one in it and three zeros.

Does anyone have an idea of how to do this? Thanks Auto Merged Post Until 24 Hrs Passes;I thought of another way of putting it that may be easier to understand.

Given an input row of "George, 4, 7, 3, 2", I would like the output to contain 4 rows of "George, 1, 0, 0, 0", 7 rows of "George, 0, 1, 0, 0", 3 rows of "George, 0, 0, 1, 0", and 2 rows of "George, 0, 0, 0, 1".
