Solution - Long subtraction
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 2 | 4 | 3 | . | 5 | 1 | 6 | |
| - | 1 | 4 | 5 | . | 6 | 4 | 9 |
| . |
2. Subtract the numbers using long subtraction method
Because the upper digit (6) in the thousandths column is too small to get a positive difference, borrow 1 from the digit (1) in the next number place which becomes (0) and get (16).
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 0 | 16 | ||||||
| 2 | 4 | 3 | . | 5 | 1 | 6 | |
| - | 1 | 4 | 5 | . | 6 | 4 | 9 |
| . |
Subtract the numbers in the thousandths column from the top number:
16-9=7
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 0 | 16 | ||||||
| 2 | 4 | 3 | . | 5 | 1 | 6 | |
| - | 1 | 4 | 5 | . | 6 | 4 | 9 |
| . | 7 |
Because the upper digit (0) 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 (10).
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |

Subtract the numbers in the hundredths column from the top number:
10-4=6
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 4 | 10 | ||||||
| 0 | 16 | ||||||
| 2 | 4 | 3 | . | 5 | 1 | 6 | |
| - | 1 | 4 | 5 | . | 6 | 4 | 9 |

Because the upper digit (4) in the tenths 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 (14).
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 2 | 14 | ||||||
| 4 | 10 | ||||||

Subtract the numbers in the tenths column from the top number:
14-6=8
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 2 | 14 | ||||||
| 4 | 10 | ||||||
| 0 | 16 | ||||||
| 2 | 4 | 3 | . | 5 | 1 | 6 | |
| - | 1 | 4 | 5 | . | 6 | 4 | 9 |
| . | 8 | 6 | 7 |
Because the upper digit (2) in the ones 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 (12).
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 3 | 12 | ||||||
| 2 | 14 | ||||||
| 4 | 10 | ||||||
| 0 | 16 | ||||||
| 2 | 4 | 3 | . | 5 | 1 | 6 | |
| - | 1 | 4 | 5 | . | 6 | 4 | 9 |
| . | 8 | 6 | 7 |
Subtract the numbers in the ones column from the top number:
12-5=7
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 3 | 12 | ||||||
| 2 | 14 | ||||||
| 4 | 10 | ||||||
| 0 | 16 | ||||||
| 2 | 4 | 3 | . | 5 | 1 | 6 | |
| - | 1 | 4 | 5 | . | 6 | 4 | 9 |
| 7 | . | 8 | 6 | 7 |
Because the upper digit (3) in the tens 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).
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 1 | 13 | ||||||
| 3 | 12 | ||||||
| 2 | 14 | ||||||
| 4 | 10 | ||||||
| 0 | 16 | ||||||

| - | 1 | 4 | 5 | . | 6 | 4 | 9 |
| 7 | . | 8 | 6 | 7 |
Subtract the numbers in the tens column from the top number:
13-4=9
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 1 | 13 | ||||||
| 3 | 12 | ||||||
| 2 | 14 | ||||||
| 4 | 10 | ||||||
| 0 | 16 | ||||||
| 2 | 4 | 3 | . | 5 | 1 | 6 | |
| - | 1 | 4 | 5 | . | 6 | 4 | 9 |
| 9 | 7 | . | 8 | 6 | 7 |
Subtract the numbers in the hundreds column from the top number:
1-1=0
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 1 | 13 | ||||||
| 3 | 12 | ||||||
| 2 | 14 | ||||||
| 4 | 10 | ||||||
| 0 | 16 | ||||||
| 2 | 4 | 3 | . | 5 | 1 | 6 | |
| - | 1 | 4 | 5 | . | 6 | 4 | 9 |
| 0 | 9 | 7 | . | 8 | 6 | 7 |
The solution is: 97.867
