Put zeros in the blank number places:

Subtract the numbers in the thousandths column from the top number:
7-0-1=6

Because the upper digit (6) in the hundredths column is too small to get a positive difference, borrow 1 from the digit (5) in the next number place which becomes (4) and get (16).

Subtract the numbers in the hundredths column from the top number:
16-7-0=9

Because the upper digit (4) in the tenths column is too small to get a positive difference, borrow 1 from the digit (4) in the next number place which becomes (3) and get (14).

Subtract the numbers in the tenths column from the top number:
14-9-0=5

Because the upper digit (3) in the ones column is too small to get a positive difference, borrow 1 from the digit (2) in the next number place which becomes (1) and get (13).
