To sort the list, start from a single element 315.

$$315$$

Insert 470 to the appropriate location in the new list.

$$315,470$$

Insert 375 to the appropriate location in the new list.

$$315,375,470$$

Insert 475 to the appropriate location in the new list.

$$315,375,470,475$$

Insert 390 to the appropriate location in the new list.

$$315,375,390,470,475$$

Insert 190 to the appropriate location in the new list.

$$190,315,375,390,470,475$$

Insert 125 to the appropriate location in the new list.

$$125,190,315,375,390,470,475$$
