Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 3 | 7 | 0 | 7 | 3 | . | 9 | 8 | 4 | |
| - | 6 | 9 | 3 | . | 4 | 4 | |||
| . |
Put zeros in the blank number places:
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 3 | 7 | 0 | 7 | 3 | . | 9 | 8 | 4 | |
| - | 6 | 9 | 3 | . | 4 | 4 | 0 | ||
| . |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the thousandths column from the top number:
4-0=4
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 3 | 7 | 0 | 7 | 3 | . | 9 | 8 | 4 | |
| - | 6 | 9 | 3 | . | 4 | 4 | 0 | ||
| . | 4 |
Subtract the numbers in the hundredths column from the top number:
8-4=4
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 3 | 7 | 0 | 7 | 3 | . | 9 | 8 | 4 | |
| - | 6 | 9 | 3 | . | 4 | 4 | 0 | ||
| . | 4 | 4 |
Subtract the numbers in the tenths column from the top number:
9-4=5
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 3 | 7 | 0 | 7 | 3 | . | 9 | 8 | 4 | |
| - | 6 | 9 | 3 | . | 4 | 4 | 0 | ||
| . | 5 | 4 | 4 |
Subtract the numbers in the ones column from the top number:
3-3=0
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 3 | 7 | 0 | 7 | 3 | . | 9 | 8 | 4 | |
| - | 6 | 9 | 3 | . | 4 | 4 | 0 | ||
| 0 | . | 5 | 4 | 4 |
Because the upper digit (7) in the tens column is too small to get a positive difference, borrow 1 from the number to the left (70) which becomes (69) and get (17).
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 6 | 9 | 17 | |||||||
| 3 | 7 | 0 | 7 | 3 | . | 9 | 8 | 4 | |
| - | 6 | 9 | 3 | . | 4 | 4 | 0 | ||
| 0 | . | 5 | 4 | 4 |
Subtract the numbers in the tens column from the top number:
17-9=8
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 6 | 9 | 17 | |||||||
| 3 | 7 | 0 | 7 | 3 | . | 9 | 8 | 4 | |
| - | 6 | 9 | 3 | . | 4 | 4 | 0 | ||
| 8 | 0 | . | 5 | 4 | 4 |
Subtract the numbers in the hundreds column from the top number:
9-6=3
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 6 | 9 | 17 | |||||||
| 3 | 7 | 0 | 7 | 3 | . | 9 | 8 | 4 | |
| - | 6 | 9 | 3 | . | 4 | 4 | 0 | ||
| 3 | 8 | 0 | . | 5 | 4 | 4 |
Write 6 in the thousands place.
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 6 | 9 | 17 | |||||||
| 3 | 7 | 0 | 7 | 3 | . | 9 | 8 | 4 | |
| - | 6 | 9 | 3 | . | 4 | 4 | 0 | ||
| 6 | 3 | 8 | 0 | . | 5 | 4 | 4 |
Write 3 in the ten thousands place.
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 6 | 9 | 17 | |||||||
| 3 | 7 | 0 | 7 | 3 | . | 9 | 8 | 4 | |
| - | 6 | 9 | 3 | . | 4 | 4 | 0 | ||
| 3 | 6 | 3 | 8 | 0 | . | 5 | 4 | 4 |
