6210001000 there are 6 zeros there are 2 ones there is 1 two there are 0 threes there are 0 fours there are 0 fives there is 1 six there are 0 sevens there are 0 eights there are 0 nines
Most of the numbers arent necessary to fill in, so I began with 0s and then started filling them in starting with the number of zeros in space one. The trick is two move one step at a time and to work the numbers with the rules until they all fit, moving too quickly or randomly will just create unecessary work
