For getting the answer of 7895*11 :
The steps are as follows

1) Divide 7895 in 2 partitions as 789 5
2) 789+ 5 = 794
3) 79 is carry which is to be added in 789 to give 789 + 79 =868 Thus we get the first part of answer as 868, second part 4, third part 5
Therefore the final answer is 86845

Another way of doing it will be
1] 76 X 11
write the digit with space in between like
7 6
now add both of them 7+6=13
write 13 in between them
7 13 6
now carry 1 from 13 to 7 and add it.you get
836 the answer.
2] 176 x 11
17 6
17+6=23
17 23 6
17+2 = 19
so we get
1936 the answer.
