Calculating numer of eggs and convert to number of trays

[Warioba]

I have a worksheet where i collect eggs 1 tray contains 30 eggs now sometime you collect 92 eggs which ypu divide by 30 and you get 3 trays and 2 eģgs and next day 103 eggs  etc, I want the formula which can add and also be able to divide number of eggs to trays. The the total ceĺl should add the decimals and if the decimal reach 30 it should increase the number of trays

In Cell A2 you enter the number of eggs collected.

In Cell B2 there's this formula: =INT(A2/30)

In Cell C2, this one: =MOD(A2,30)

I'm sorry. I need you to walk through what each row and column represent here in your spreadsheet. It doesn't pop off the sheet making sense to me, so though I might be able to figure it out, it would help if you just explained it.

(FYI, I'm going to be on a trip beginning tomorrow, and will have limited time from here on out to look at my computer, until next week. If your reply comes through and I have a moment, I'll give it a try)
