| 3 | 0 | 7 | . | 0 | 0 | |
| - | 6 | 0 | . | 4 | 2 | |

2. Subtract the numbers using long subtraction method
Because the upper digit (0) in the hundredths column is too small to get a positive difference, borrow 1 from the number to the left (7.0) which becomes (6.9) and get (10).
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 6 | 9 | 10 | ||||
| 3 | 0 | 7 | . | 0 | 0 | |

Subtract the numbers in the hundredths column from the top number:
10-0-2=8
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 6 | 9 | 10 | ||||
| 3 | 0 | 7 | . | 0 | 0 | |
| - | 6 | 0 | . | 4 | 2 | |

Subtract the numbers in the tenths column from the top number:
9-4=5
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 6 | 9 | 10 | ||||
| 3 | 0 | 7 | . | 0 | 0 | |
| - | 6 | 0 | . | 4 | 2 | |
| . | 5 | 8 |
Subtract the numbers in the ones column from the top number:
6-0=6
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 6 | 9 | 10 | ||||
| 3 | 0 | 7 | . | 0 | 0 | |
| - | 6 | 0 | . | 4 | 2 | |
| 6 | . | 5 | 8 |
Because the upper digit (0) in the tens column is too small to get a positive difference, borrow 1 from the digit (3) in the next number place which becomes (2) and get (10).
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 2 | 10 | |||||
| 6 | 9 | 10 | ||||
| 3 | 0 | 7 | . | 0 | 0 | |
| - | 6 | 0 | . | 4 | 2 | |

Subtract the numbers in the tens column from the top number:
10-6=4
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 2 | 10 | |||||
