    Column by column: 528,523 − 123,456

    • Ones: 3 is less than 6 — borrow 1 ten: tens 2 → 1; 13 − 6 = 7 — write 7.
    • Tens: after borrowing, 1; 1 is less than 5 — borrow 1 hundred: hundreds 5 → 4; 11 − 5 = 6 — write 6.
    • Hundreds: after borrowing, 4; 4 − 4 = 0 — write 0.
    • Thousands: 8 − 3 = 5 — write 5.
    • Ten thousands: 2 − 2 = 0 — write 0.
    • Hundred thousands: 5 − 1 = 4 — write 4.

    528,523 − 123,456 = 405,067
