Subtracting 315 from 353 leaves us with 38.
Bring next digit (4) of the dividend behind the 38 and repeat the process: 384 / 45

Advancing to step 8:
384 divided by 45 is 8 with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 1179778.0
Deduct 360 from 384 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

240 divided by 45 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 1179778.5
If we subtract 225 from 240, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 10:
45 goes into 150 3 times with a remainder of 15.
The next digit of our result is 3. 
Result so far: 1179778.53
Subtracting 135 from 150 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
The number 45 fits into 150 3 times, leaving a remainder of 15.
Put 3 as the next digit of the answer.
