99204275 ÷ 448 
Our goal is to divide 99204275 by 448.

Let's proceed to step 1:
If we divide 9 by 448, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 448

Going ahead to step 2:
The number 448 fits into 99 0 times, leaving a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Append the next digit (2) from the dividend to 99 and continue with: 992 / 448

On to step 3:
448 can be fit into 992 2 times, resulting in a remainder of 96.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 896 from 992, we get 96.
Bring next digit (0) of the dividend behind the 96 and repeat the process: 960 / 448

Step 4:
The number 448 fits into 960 2 times, leaving a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we subtract 896 from 960, we get 64.
Fetch the next digit (4) from the dividend, attach it to 64 and continue: 644 / 448

Step 5:
448 goes into 644 1 times with a remainder of 196.
Put 1 as the next digit of the answer. 
Result so far: 221.0
The remainder is 196 after subtracting 448 from 644.
Grab the next digit (2) from the dividend, add it to 196, then carry on: 1962 / 448

Step 6:
448 goes into 1962 4 times with a remainder of 170.
Write down 4 as next digit of the result. 
Result so far: 2214.0
The remainder is 170 after subtracting 1792 from 1962.
Grab the next digit (7) from the dividend, add it to 170, then carry on: 1707 / 448

Step 7:
If we divide 1707 by 448, we get 3 and a remainder of 363.
Put 3 as the next digit of the answer. 
Result so far: 22143.0
Subtract 1344 from 1707 to get 363.
Fetch the next digit (5) from the dividend, attach it to 363 and continue: 3635 / 448

Step 8:
The number 448 fits into 3635 8 times, leaving a remainder of 51.
Put 8 as the next digit of the answer. 
Result so far: 221438.0
If we subtract 3584 from 3635, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 9:
448 goes into 510 1 times with a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 221438.1
Subtracting 448 from 510 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 10:
The number 448 fits into 620 1 times, leaving a remainder of 172.
Put 1 as the next digit of the answer. 
Result so far: 221438.11
The remainder is 172 after subtracting 448 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

The final outcome is 221438.11, with a leftover of 0.172.
