Hmmm.....
	push	ebx
	xor	ecx, ecx
divloop:
	xor	edx, edx
	inc	ecx
	div	100
	xchg	eax, edx
	aam
	xchg	ah, al
	shl	eax, 16
	mov	ebx, eax
	mov	eax, edx
	xor	edx, edx
	div	100
	xchg	eax, edx
	aam
	xchg	ah, al
	mov	bx, ax
	or	ebx, '0000'
	push	ebx
	test	edx, edx
	mov	eax, edx
	jnz	divloop
	
afterdivloop
	pop	eax
	stosd
	loop	afterdivloop

Problem is it has up to 3 leading zeros.
Threre are also better ways to do the "pop stosd loop"
