Do the subnetting of 192.168.10.0 using CIDR value 29.?

According to your example:-

Step 1: Calculate total number of subnet. How to calculate ?

number of subnet = 2 ^n     n means number of borrow bits

In this case , you have borrowed 5 bits from host part , so total number of subnets are as following:-

number of subnet = 2^5 

number of subnet = 32

And each subnet is having 8 ip addresses. 

Step 2: Calculate network id and broadcast id for each subnet with the help of block size. Now the question is that how to calculate block size. Very simple. we can also represent /29 to 255.255.255.248. To calculate block size , you have to subtract the last octet value from 255.

Block size = 255-248 = 7

How to calculate Network and Broadcast id ??

192.168.10.0 255.255.255.248 

start from zero

192.168.10.0 /29 Network id for 1st subnet

To calculate Broadcast ID, add block size in the octet , which is having the subnet bits. In this case, Add block size in last octet.

192.168.10.7/29 Broadcast ID

2nd subnet

192.168.10.8/29 - Network ID

192.168.10.15/29- Broadcast ID

3rd subnet

192.168.10.16/29 Network ID

192.168.10.23/29 Broadcast ID

At the end 

Last subnet

192.168.10.248/29 Network ID

192.168.10.255/29 Broadcast ID

Hope it helps
