Partial quotient times divisor
 




  

  

   

  

  



  

  

  

 

  

  
  
  
Subtract and bring down next term
 




  

  

  
Divide by first term of divisor again
   

  

  



  

  

  

 

  

  
  
  

 




  

  

  

   

  

  



  

  

  

 

  

  
  
  

 

  

  
  
  
Multiply by new quotient term
