Step 302: 294378 + 978 = 295356
Step 303: 295356 + 978 = 296334
Step 304: 296334 + 978 = 297312
Step 305: 297312 + 978 = 298290
Step 306: 298290 + 978 = 299268
Step 307: 299268 + 978 = 300246
Step 308: 300246 + 978 = 301224
Step 309: 301224 + 978 = 302202
Step 310: 302202 + 978 = 303180
Step 311: 303180 + 978 = 304158
Step 312: 304158 + 978 = 305136
Step 313: 305136 + 978 = 306114
Step 314: 306114 + 978 = 307092
Step 315: 307092 + 978 = 308070

So, 978*315 = 308070
