You have 5*651 dollars in five dollar bills, or $3255.
You have 10*819 dollars in ten dollar bills, or $8190. The amount of money in each stack must end in zero since all multiples of ten end in zero, and some multiples of 5 end in 0.
Also, you cannot have more than $3255 in the stacks, since you only have that much in five dollar bills.
So the largest amount of money you can have in each stack is $3220.
This would be 3250/5 five dollar bills and 3220/10 ten dollar bills.
So there would be 650 bills in the stack of $5 bills and 322 bills in the stack of $10 bills.
