There is a French idiom, which translated word-for-word is
Let's cut the apple in two
It means both parties will benefit from 50% of the requested initial negotiated deal.
Can this idiom be also used in English with the same meaning:
‘Let's cut (split) the apple in half’ ?
In England we sometimes use a similar idiom: meet me in the middle, or meet me halfway, or, equivalently, let's split the difference.
They all mean the same, that is, when two parties are negotiating and one wants to sell high and the other buy low, they can agree on a compromise price that's halfway between each of their offers.

There's an idiom
To divide something into two equal parts. (The fifty means 50 percent.)
- Tommy and Billy divided the candy fifty-fifty.
- The robbers split the money fifty-fifty.
You could consider saying, "Let's go halves on something". To go halves means:
to share the whole amount (of something with another person): 'to go halves on an orange'
Note: You should not use "go half on something". It doesn't have the same meaning.
You could also consider using "Let's go (or split something) half and half". Half and half means:
(adv) in two equal parts
"Let's go half and half" is more broadly used when you suggest two parties split the bill or expenses, e.g., restaurant, bar and taxi fare, etc.

Meet me in the middle, meet me halfway, or, equivalently, let's split the difference all mean the same as each other that is, when two parties are negotiating and one wants to sell high and the other buy low, they can agree on a compromise price that's halfway between each of their offers, but they are different than the meaning of the French idiom.

Splitting the difference is when negotiating the seller proposes a price of 10, the buyer proposes 5, and they agree to 7.5. It is a situation of compromise. The French idiom is when a seller offers to collaborate on something with another seller and the profits are split. They work together, make something that costs 6, sell it for 10, and each keep 2. It's the kind of deal you will never get with a record company even if they do split the difference, e.g. you ask for 60% of revenue, they offer 4% to you, eventually you split the difference and get a contract awarding you 6% of the revenue. That's not a typo, splitting the difference is a little different than meeting halfway or in the middle, it's not necessarily implied that the split is even, if it were you would get 36%, which is still a far cry from the 50% that the OP says the French idiom implies.
The key idea I think though is that the phrase represents a mutually beneficial offer of cooperation rather than a case where the sides are penny pinching, so I might even say that, "I'll scratch your back if you scratch mine," hits closer to the mark (though still not perfect at all). http://idioms.thefreedictionary.com/I'll+scratch+your+back+if+you+scratch+mine
Sharing the spoils also comes to mind. A common idiom in the US at least is, "going Dutch," which has a derivative, "sharing Dutch," they do fail to capture the 50-50 nature of the split though. https://en.wikipedia.org/wiki/Going_Dutch It's not exactly an idiom.. but in English I think saying, "we'll split the profits 50-50," would be most common when offering that arrangement.
Footnote: I felt compelled to answer because I saw that the answer with many votes in the lead at the time was absolutely not the same meaning and some answers with many fewer votes were much closer, e.g. divide 50-50 and even Steven.
You can split apples in half, and both sides will be happy (unless they planned to eat the apple later). Sometimes both sides are unhappy with the outcome of splitting, or if you just want a funnier or more visceral version of split the different you can split the baby
Definition (from a site dedicated to mediation):
‘Splitting the Baby’ – Thomas Crowley states that because of the relaxation of rules of evidence in arbitration, and the power of the arbitrator to ‘do equity’ (make decisions based on fairness), the arbitrator may render an award that, rather than granting complete relief to one side, splits the baby by giving each side part of what they requested.
