Why are you subtracting a string?

Create a multiplier array. Set it to a value of 1 (i.e., a single element with the value set to 1).
Create a result array. Set it to a value of 0 (i.e., a single element with the value set to 0).
Create a secondary array. It's value will be set later.
Loop from the last char to the first char.
	Create a product array by multiplying the char value by the multiplier array (note: 5x = x + x + x + x + x).
		Initialize product array to the size of the multiplier array plus 1 (set each element to a value of 0).
		Loop from 1 to char value.
			Assign the product array the result of binary adding the product array and the multiplier array.
	Binary add the product array to the value array and assign it to the value array, adding a head byte if necessary.
	Multiply the multiplier array by 10 (note: 10x = x+x+x+x+x+x+x+x+x+x) (optimization: 10x = 8x + 2x).
		Copy the multiplier array to the secondary array.
		Multiply secondary array by 2.
			Prefix a head byte to the secondary array.
			Shift all the bits in the secondary array to the left by 1 bit (discard the first bit).
		Multiply multiplier array by 8.
			Prefix a head byte to the multiplier array.
			Shift all the bits in the multiplier array to the left by 3 bits (discard the first 3 bits).
		Binary add the secondary array and the multiplier array and assign the result to the multiplier array.
		If the first byte in the multiplier is 0, remove it (this isn't necessary, but will reduce memory used).
Repeat loop until first char is reached and processed.
Remove any bytes from the head of the value array that are 0 (they are meaningless, just as the zeroes on 00000123 are meaningless).
