  "abstract": "We present a determination of the magnitude of the Cabibbo-Kobayashi-Maskawa matrix element $|V_{cb}|$ using the decay $B\\to D\\ell\\nu_\\ell$ ($\\ell=e,\\mu$) based on 711 fb$^{-1}$ of $e^+e^-\\to \\Upsilon(4S)$ data recorded by the Belle detector and containing $772 \\times 10^6$ $B\\bar{B}$ pairs. One $B$ meson in the event is fully reconstructed in a hadronic decay mode while the other, on the signal side, is partially reconstructed from a charged lepton and either a $D^+$ or $D^0$ meson in a total of 23 hadronic decay modes. The isospin-averaged branching fraction of the decay $B\\to D\\ell\\nu_\\ell$ is found to be $\\mathcal{B}(B^0 \\to D^- \\ell^+ \\nu_{\\ell})=(2.31\\pm 0.03(\\mathrm{stat})\\pm 0.11(\\mathrm{syst}))\\%$. Analyzing the differential decay rate as a function of the hadronic recoil with the parameterization of Caprini, Lelouch and Neubert and using the form-factor prediction $\\mathcal{G}(1)=1.0541\\pm 0.0083$ calculated by FNAL/MILC, we obtain $\\eta_\\mathrm{EW}|V_{cb}|=(40.12\\pm 1.34)\\times 10^{-3}$, where $\\eta_\\mathrm{EW}$ is the electroweak correction factor. Alternatively, assuming the model-independent form-factor parameterization of Boyd, Grinstein and Lebed and using lattice QCD data from the FNAL/MILC and HPQCD collaborations, we find $\\eta_\\mathrm{EW}|V_{cb}|=(41.10 \\pm 1.14)\\times 10^{-3}$.",
