Congratulations! I think that you have done a great job. Yes, that is a passive sentence.
I just have one little suggestion. I feel that your sentence needs the word “going”:
The ten children are GOING to be divided into two groups.
Why? Because I think that this passive sentence comes from an active sentence something like:
The teachers are GOING to divide the children into two groups.
“The ten children are to be divided into two groups” might come from “The teachers are to divide the children into two groups.” That is like an order or command. I do not think that is the meaning that you wish to give.
============
First, please post your sentence properly and correctly.
Your sentence “Ten children [color=red]is to be divided in [color=red]tho two [color=red]group.” is unacceptable.
It should have been : The ten children are to be divided into two groups.
This is a sentence in the passive voice where the object (The ten children) functions as the subject but does not perform the activity. Whether a sentence is passive or active is determined by the form/structure of the transitive verb used in it. See below how a sample verb (speak) changes into its various passive constructions, and note the forms in which they appear; or, compare active forms and their corresponding passive forms meticulously.
ACTIVE VOICE > PASSIVE VOICE
speak/speaks > is/are/am spoken
is/are/am speaking > is/am/are being spoken
has/have spoken > has/have been spoken
spoke > was/were spoken
was/were speaking > was/were being spoken
had spoken > had been spoken
will speak > will be spoken
will have spoken > will have been spoken
T_H_Lawrence:
you showed many form of changing active voice into passive. But I just don’t understand which form is acting in my sentence. And what will be the sentence if I turn it into active voice.
===============
Yes, 'are to divide, ‘going to divide’ etc constructions will also change like ‘will speak’: that is, are to be divided, going to be divided etc.
If you want to turn it into active voice, it will appear thus: “Someone is/They are to divide the ten children into two groups”.
By the way, I would deem it the moral duty of the people who, MAYBE, know some English to comment on the learners’ “mistakes.” Unless errors are corrected, how can a discerning learner learn the language?
It means like “will speak> will be spoken,speak/speaks> is/are/am spoken etc”
'are to divide>are to be divided and ‘going to divide’>going to be divided are also two forms?
Children are to divide three group.(here children are dividing them-self.) correct?
Children are to be divide into three group( here some one is dividing the children into three group) correct?
(Type I) - I will phone her, if I have her number. [Real for all times]
(Type III) - I would have phoned her, if I had had her number. [Unrealized past]
I don’t know about the term ‘unrealistic present’ but I would say that ‘would’ is a conditional.

in conditionals with words like if and what if. In these sentences the main verb is usually in the past tense: I would give her a call if I could find her number.
If I had the money I’d buy a new car.

If he got a new job he would probably make more money.
What if he lost his job. What would happen then?
