#### Answer

25,866

#### Work Step by Step

1. Subtract the ones column by regrouping, so 4 becomes 14.
14 - 8 = 6
2. Subtract the tens column, where 0 becomes 9 after regrouping.
9 - 3 = 6
3. Subtract the hundreds column, where 7 becomes 6. We regroup so 6 becomes 16.
16 - 8 = 8
4. Subtract the thousands column, where 9 becomes 8.
8 - 3 = 5
5. Subtract the ten-thousands column.
9 - 7 = 2
Therefore, the answer is 25,866.
