I was thinking of subtracting a percentage off the previous value but that will not reduce to zero in 10 steps especially given that the number can have up to 4 decimals. Any obvious solution?

Dunno Jos, but wouldn't the step value be (InitialValue / 10) ?

If the number is not 'easily' divided by 10, ie (InitialValue / 10) * 10 != InitialValue, you could always populate a Collection with the first 9 values and the tenth value would be InitialValue - first 9 stepvalues

I would go for the collection approach regardless. You feed the collection and loop - removing one item at a time - until it's empty
