(a)
652944 = 600000 + _____ + 900 + 44
652944 = 600000 + _____ + 944
652944 - 600000 - 944 = 52000
(b)
166617 = _____ + 60000 + 6000 + 600 + 10 + 7

166617 - 66617 = 100000
(c)
587393 = 500000 + 80000 + _____ + 300 + 90 + 3
587393 = 580000 + _____ + 393
587393 - 580000 - 393 = 7000
(d)
775424 = 700000 + 70000 + 5000 + _____ + 20 + 4
775424 = 775000 + _____ + 24
775424 - 775000 - 24 = 400
