Record the quotient 7 as the next digit in the result. 
Result so far: 63367.0
Deduct 1008 from 1147 and we're left with 139.
Fetch the next digit (8) from the dividend, attach it to 139 and continue: 1398 / 144

Step 8:
If we divide 1398 by 144, we get 9 and a remainder of 102.
The next digit of our result is 9. 
Result so far: 633679.0
If we subtract 1296 from 1398, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 9:
When dividing 1020 by 144, we get 7 with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 633679.7
The remainder is 12 after subtracting 1008 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
144 goes into 120 0 times with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 633679.7
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 11:
144 can be fit into 1200 8 times, resulting in a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 633679.708
Subtract 1152 from 1200 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 12:
The number 144 fits into 480 3 times, leaving a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 633679.7083
Subtract 432 from 480 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
144 can be fit into 480 3 times, resulting in a remainder of 48.
The next digit of our result is 3. 
Result so far: 633679.70833
Deduct 432 from 480 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 633679.70833 with a remaining 4.8e-05.
