(a)
419632 = 400000 + _____ + 600 + 32
419632 = 400000 + _____ + 632
419632 - 400000 - 632 = 19000
(b)
179827 = _____ + 70000 + 9000 + 800 + 20 + 7

179827 - 79827 = 100000
(c)
182734 = 100000 + 80000 + _____ + 700 + 30 + 4
182734 = 180000 + _____ + 734
182734 - 180000 - 734 = 2000
(d)
162352 = 100000 + 60000 + 2000 + _____ + 50 + 2
