Using float in C

I'm very new to C. If I had a program like the one below, I was hoping someone could tell me how I should edit it so that the lines "printf("\n%20s%20f", "Half of 1", div1);" and "printf("\n%20s%20f", "Half of 2", div2);" output decimals without too many excess spaces. Currently when outputted, they are in decimal form but don't give remainders and have quite a few zeros. I'm really stuck here and have spent way too much time on this. I'd really appreciate any help.

#include<stdio.h>

int main(void)
{
int int1, int2;
float div1, div2;

printf("\nGive two integers: ");
scanf("%d%d", &int1, &int2);

div1 = int1 / 2
div2 = int2 / 2

printf("\n%20s%20d", "First Number", int1);
printf("\n%20s%20d", "Second Number", int2);
printf("\n%20s%20f", "Half of 1", div1);
printf("\n%20s%20f", "Half of 2", div2);

return 0;
}

 Recognitions: Homework Help The division will be an integer division, change the code to: div1 = (float)int1 / 2.; div2 = (float)int2 / 2.; Note if either number in a binary operation is a float, then the other number will be "promoted" to a float as well. If you have a c reference manual, look up type promotion.
 Thanks.

Using float in C

Here is another issue about "printf"
see http://www.google.com/search?hl=en&q=printf&aq=f&oq= for a detail reference.
If you want to limit the strengh of output. You could easily change the to

%10f which means you should limit the output to 10 bit spaces.
