Solution - Long multiplication
Step-by-step explanation
1. Rewrite the numbers from top to bottom aligned to the right
| Place value | ones | . | tenths | hundredths | thousandths | ten thousandths | hundred thousandths |
| 1 | . | 6 | 3 | 3 | 4 | 9 | |
| × | 5 | . | 2 | 2 | 4 | 4 | 3 |
| . |
Ignore the decimal points and multiply as if these are whole numbers (as if each most right digit is the ones digit):
In this case we removed 10 decimal place(s). So once calculated, the result will be reduced by the factor of 10,000,000,000.

2. Multiply the numbers using long multiplication method
Start by multiplying the ones digit (3) of the multiplier 522,443 by each digit of the multiplicand 163,349, from right to left.
Multiply the ones digit (3) of the multiplicator by the number in the ones place value:
3×9=27
Write 7 in the ones place.
Because the result is greater than 9, carry the 2 to the tens place.

| 7 | |||||||||||
Multiply the ones digit (3) of the multiplicator by the number in the tens place value and add the carried number (2):
3×4+2=14
Write 4 in the tens place.
Because the result is greater than 9, carry the 1 to the hundreds place.

3,266,980,000 is the fifth partial product.
Proceed by multiplying the hundred thousands digit (5) of the multiplier (522,443) by each digit of the multiplicand (163,349), from right to left.
Because digit (5) is in hundred thousands place, we shift partial result by 5 place(s) by placing 5 zero(s).

Because we have 10 digit(s) to the right of the decimal point in the numbers that are being multiplied, we move the decimal point 10 time(s) to the left (reducing the result by the factor of 10,000,000,000) to get the final result:
The solution is: 8.5340541607
