Why the answer is 191? As far as I understand, we need to count numbers from 1000 to 1234 without 00. There are only 12 of them:
1000
1001
1002
1003
1004
1005
1006
1007
1008
1009
1100
1200
So 1234 - 1000 - 12 = 222. Where am I wrong? Thanks.

No. We need to count numbers from 1000 to 9999 without 00.
Result - 8829 - we should divide by 1234 - 7, remainder 191.
Remainder is the answer.

So answer is 191.
