Step 7:
25 divided by 4 is 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 2254196.0
Subtracting 24 from 25 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 4

Advancing to step 8:
4 goes into 18 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 22541964.0
If we subtract 16 from 18, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
4 goes into 20 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 22541964.5
Deduct 20 from 20 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
4 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 22541964.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
4 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 22541964.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 22541964.5, with a leftover of 0.0.
