888 can be fit into 4419 4 times, resulting in a remainder of 867.
Write down 4 as next digit of the result. 
Result so far: 9744.0
Subtract 3552 from 4419 to get 867.
Grab the next digit (8) from the dividend, add it to 867, then carry on: 8678 / 888

On to step 8:
If we divide 8678 by 888, we get 9 and a remainder of 686.
The next digit of our result is 9. 
Result so far: 97449.0
Subtract 7992 from 8678 to get 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Step 9:
When dividing 6860 by 888, we get 7 with a remainder of 644.
Record the quotient 7 as the next digit in the result. 
Result so far: 97449.7
If we take 6216 away from 6860, we end up with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Step 10:
The number 888 fits into 6440 7 times, leaving a remainder of 224.
Put 7 as the next digit of the answer. 
Result so far: 97449.77
If we subtract 6216 from 6440, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Our division results in 97449.77 with a remaining 0.224.
