/* int _DivUnsArrByPwrOf10(a,n,p)
 *
 * ARGUMENT
 *      unsigned        a[];
 *      int             p;            power of 10 to divide by
 *      int             n;            number of digits
 *
 * DESCRIPTION
 *      Divides a number of n words (a) by a power of 10, c= a/10^p,
 *  a>=0, p>0, truncating the result, c is correct only if a/10^p<2^79.
 *
 * SIDE EFFECTS
 *      The value of a is destroyed.
 *
 * RETURNS
 *      None. (always succeeds)
