Multistep form using ajax in Laravel 8

Question

I created a multistep form but I didn't use Ajax in it because I have no idea about Ajax. I have had to code a lot in my controller and routes for the way I created it which is probably not optimized. I'm new to Laravel so I can't find any solution.

How can I do this with ajax?

Controller

public function InitialCreateReport(Request $request){
        $request->session()->forget('report');
        $data['fiscalyear'] = FiscalYear::all();
        $data['month'] = Months::all();
        $data['report_type'] = ReportType::all();
        $data['report'] = $request->session()->get('report');
        return view('adc.reports.create-report', $data);
    }

    public function PostInitialCreateReport(Request $request){
        $validatedData = $request->validate([
            'fiscalyear' => 'required',
            'month' => 'required',
            'report_type' => 'required',
        ]);

        if (empty($request->session()->get('report'))) {
            $report = new Report();
            $report->fill($validatedData);
            $request->session()->put('report', $report);
        } else {
            $report = $request->session()->get('report');
            $report->fill($validatedData);
            $report->session()->put('report', $report);
        }
        return redirect()->route('adc.create.rent.certificate');
    }

    public function CreateRentCertificateReport(Request $request)
    {
        $data['report'] = $request->session()->get('report');
        $data['reports'] = Report::distric()->status(1)->get();
        return view('adc.reports.start-create-report', $data);
    }

    public function PostCreateRentCertificateReport(Request $request)
    {
        $report = $request->session()->get('report');
        $request->session()->put('report', $report);
        return redirect()->route('adc.preview.rent.certificate.report');
    }

    public function PreviewRentCertificateReport(Request $request){
        $report = $request->session()->get('report');
        return view('adc.reports.preview-rent-certificate-report', compact('report', $report));
    }

    public function PostPreviewRentCertificateReport(Request $request){
        $report = $request->session()->get('report');
        return redirect()->route('adc.save.rent.certificate.report');
    }

    public function SaveRentCertificateReport(Request $request){
        $report = $request->session()->get('report');
        return view('adc.reports.save-rent-certificate-report', compact('report', $report));
    }

    public function PostSaveRentCertificateReport(Request $request)
    {
        $report = $request->session()->get('report');
        $reports = new Report;
        $reports->column_one = $report->sum('column_one');
        $reports->column_two = $report->sum('column_two');
        $reports->fiscal_year = $report->fiscalyear;
        $reports->month = $report->month;
        $reports->report_type = $report->report_type;
        $reports->save();
        $notification = array(
            'message' => 'Report Created Successfully',
            'alert-type' => 'success'
        );
        return redirect()->route('adc.pending.report')->with($notification);
    }

 Route::get('/initial/create/report', [AdcController::class,'InitialCreateReport'])->name('inital.create.report');
    Route::post('/initial/create/report', [AdcController::class,'PostInitialCreateReport'])->name('inital.create.report.post');
