var pages= document.getElementById("pages").value;
    
    if(total_pages == ""){
    
        alert("Please enter number of pages");
    }
    else{
        
        for(var start=1;start<=total_pages;start++){
        
            var divRefer = document.querySelector('div.temp');

            var divToCreate = document.createElement('div');
            divToCreate.style.width="595pt";
            divToCreate.style.height="842pt";
            divToCreate.style.pageBreakAfter="always"; 
            div_id++;
            divToCreate.setAttribute("id","display_next"+div_id);
            var div_deleteId="display_next"+div_id;
            divToCreate.setAttribute("Contenteditable","true");
            //divToCreate.innerHTML="Insert Your Text Here";
            delete_btn.setAttribute("onclick","delete_div("+div_deleteId+");");
            var textarea= document.createElement('textarea');
            textarea.setAttribute("Contenteditable","true");
            id++;
            var text_edit="text_edit"+id;
            textarea.setAttribute("id",text_edit);
            //divToCreate.setAttribute("class","ck-editor__editable");
            divReference.parentNode.appendChild(divToCreate);
            divToCreate.appendChild(textarea);
            divToCreate.appendChild(delete_btn);
            var editor = new FroalaEditor("textarea#"+text_edit, {
            height: '542',

             
            });
            
        }
        
        }

}

function CustomizationPlugin( editor ) {

}

NOTE: i attached screenshot,kindly check it.

enter image description here

this is how its moving from div.actually toolbar is created dynamically and appended to div.
