Step 8:
645 can be fit into 4744 7 times, resulting in a remainder of 229.
Write down 7 as next digit of the result. 
Result so far: 141167.0
If we take 4515 away from 4744, we end up with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Step 9:
If we divide 2290 by 645, we get 3 and a remainder of 355.
The next digit of our result is 3. 
Result so far: 141167.3
If we subtract 1935 from 2290, we get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Moving on to step 10:
645 goes into 3550 5 times with a remainder of 325.
Put 5 as the next digit of the answer. 
Result so far: 141167.35
The remainder is 325 after subtracting 3225 from 3550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 11:
645 goes into 3250 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 141167.355
Subtract 3225 from 3250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 141167.355 with a remaining 0.0025.
