(a)
878771 = 800000 + _____ + 700 + 71
878771 = 800000 + _____ + 771
878771 - 800000 - 771 = 78000
(b)
563937 = _____ + 60000 + 3000 + 900 + 30 + 7

563937 - 63937 = 500000
(c)
232238 = 200000 + 30000 + _____ + 200 + 30 + 8
232238 = 230000 + _____ + 238
232238 - 230000 - 238 = 2000
(d)
223162 = 200000 + 20000 + 3000 + _____ + 60 + 2
223162 = 223000 + _____ + 62
223162 - 223000 - 62 = 100
