Print an integer using putchar only

#include <stdio.h>

int main (int argc, char** argv) {
       int i=390487;
       int base=10;
       int remainder=0;
       for (remainder=i/base;

      base*=10,remainder=i/base);

       while (base>0) {
               putchar('0'+remainder/base);
               remainder=remainder-(remainder/base)*base;
               base/=10;
       }
       putchar('\n');
