Progress event response is fluctuating (increase & decrease in percentage)

Progress event response is fluctuating (increase & decrease in percentage),

Whenever I install the app for the first time, and the file download starts, there are visible decrement and increment in received percentage that is fluctuating.

return RNFetchBlob.config({
     path: path
   })
     .fetch("GET", JSON.parse(dbPathURL))
     .progress({ count : 20 },(received, total) => {
       debugger;
       console.log("progress", received / total);
       let percentage = Math.floor(received/total*100) ;
       store.dispatch(setDownloadPercentage(percentage));
     })
