well assuming there's 6 friends, which you did not state, if you divided it into 6ths then everyone will get one piece

The value of the first 7 from the left is 70.
If you divide 70 by 10, you get the value of the second seven, 7.
Another way to know this is equivalent fractions:

10 X 7 = 70
1 X 7 = 7
There is only two, 5 and 13
