Solution - Long multiplication

Because the thousands digit of the multiplicator equals 0, skip to the next digit.

Proceed by multiplying the ten thousands digit (6) of the multiplier (260,000) by each digit of the multiplicand (343,400), from right to left.

Because digit (6) is in ten thousands place, we shift partial result by 4 place(s) by placing 4 zero(s).

Multiply the ten thousands digit (6) of the multiplicator by the number in the ones place value:
6×0=0

Write 0 in the ten thousands place.

Multiply the ten thousands digit (6) of the multiplicator by the number in the tens place value:
6×0=0

Write 0 in the hundred thousands place.

Multiply the ten thousands digit (6) of the multiplicator by the number in the hundreds place value:
6×4=24

Write 4 in the millions place.

Because the result is greater than 9, carry the 2 to the ten millions place.

Multiply the ten thousands digit (6) of the multiplicator by the number in the thousands place value and add the carried number (2):
6×3+2=20

Write 0 in the ten millions place.

Because the result is greater than 9, carry the 2 to the hundred millions place.

Multiply the ten thousands digit (6) of the multiplicator by the number in the ten thousands place value and add the carried number (2):
6×4+2=26

Write 6 in the hundred millions place.

Because the result is greater than 9, carry the 2 to the billions place.

Multiply the ten thousands digit (6) of the multiplicator by the number in the hundred thousands place value and add the carried number (2):
6×3+2=20

Write 0 in the billions place.

Because the result is greater than 9, carry the 2 to the ten billions place.

20,604,000,000 is the first partial product.

Proceed by multiplying the hundred thousands digit (2) of the multiplier (260,000) by each digit of the multiplicand (343,400), from right to left.

Because digit (2) is in hundred thousands place, we shift partial result by 5 place(s) by placing 5 zero(s).

Multiply the hundred thousands digit (2) of the multiplicator by the number in the ones place value:
2×0=0

Write 0 in the hundred thousands place.

Multiply the hundred thousands digit (2) of the multiplicator by the number in the tens place value:
2×0=0

Write 0 in the millions place.

Multiply the hundred thousands digit (2) of the multiplicator by the number in the hundreds place value:
2×4=8

Write 8 in the ten millions place.

Multiply the hundred thousands digit (2) of the multiplicator by the number in the thousands place value:
2×3=6

Write 6 in the hundred millions place.

Multiply the hundred thousands digit (2) of the multiplicator by the number in the ten thousands place value:
2×4=8

Write 8 in the billions place.

Multiply the hundred thousands digit (2) of the multiplicator by the number in the hundred thousands place value:
2×3=6

Write 6 in the ten billions place.

68,680,000,000 is the second partial product.

20604000000+68680000000=89284000000 long addition steps can be seen here

The solution is: 89,284,000,000
