Perform the written multiplication and division shown in the image.

Written Multiplication and Division:

The image displays various handwritten arithmetic problems, primarily focusing on multiplication and division, solved using the traditional column method. Here's a breakdown of the visible calculations:

Multiplication Examples:

• 4390456 × 392: This problem appears to be worked out, with intermediate steps shown. The final result is not explicitly stated but the process of multiplication is visible.
• 2557438 × 673: Similar to the above, the multiplication process is depicted with intermediate calculations.
• 3678367 × 647: Again, the multiplication steps are shown.

Division Examples:

• 29575915 ÷ 328: The division is presented in a 'long division' format, with the quotient and remainder visible. The result is shown as 90170 with a remainder of 255, or approximately 90170.7.
• 4803473 ÷ 658: Long division is shown, with intermediate steps. The result appears to be 7300 with a remainder of 173, or approximately 7300.26.
• 7341684 ÷ 672: Long division is depicted. The result appears to be 10925 with a remainder of 64, or approximately 10925.4.

Other Numbers and Calculations:

• 3327659 and 5468484 are written, possibly as problems or results.
• Numbers like 5574464, 1856452, 3009666, 2049323, 3342339, 3163248, 9890199, and 355556 are present, potentially as final answers or new problems.
• A small section on the right edge shows a calculation that seems to involve addition and division: 325, 325, 2525, 23575. The calculation appears to be 23575 / (325 + 325 + 2525) = 23575 / 3175 = 7.426...
