99208496 divided by 398 
Our goal is to divide 99208496 by 398.

Step 1:
398 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 398

Advancing to step 2:
If we divide 99 by 398, we get 0 and a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Fetch the next digit (2) from the dividend, attach it to 99 and continue: 992 / 398

On to step 3:
If we divide 992 by 398, we get 2 and a remainder of 196.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 196 after subtracting 796 from 992.
Bring next digit (0) of the dividend behind the 196 and repeat the process: 1960 / 398

Moving on to step 4:
1960 divided by 398 is 4 with a remainder of 368.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we subtract 1592 from 1960, we get 368.
Append the next digit (8) from the dividend to 368 and continue with: 3688 / 398

Step 5:
If we divide 3688 by 398, we get 9 and a remainder of 106.
Record the quotient 9 as the next digit in the result. 
Result so far: 249.0
If we subtract 3582 from 3688, we get 106.
Fetch the next digit (4) from the dividend, attach it to 106 and continue: 1064 / 398

Step 6:
398 can be fit into 1064 2 times, resulting in a remainder of 268.
Use 2 as the next digit of our solution. 
Result so far: 2492.0
If we subtract 796 from 1064, we get 268.
Take the next digit (9) from the dividend and append it to 268, then repeat: 2689 / 398

Let's proceed to step 7:
398 goes into 2689 6 times with a remainder of 301.
Put 6 as the next digit of the answer. 
Result so far: 24926.0
If we subtract 2388 from 2689, we get 301.
Include the next digit (6) from the dividend after 301, then repeat: 3016 / 398

Advancing to step 8:
The number 398 fits into 3016 7 times, leaving a remainder of 230.
The next digit of our result is 7. 
Result so far: 249267.0
Subtracting 2786 from 3016 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 9:
398 can be fit into 2300 5 times, resulting in a remainder of 310.
Put 5 as the next digit of the answer. 
Result so far: 249267.5
If we subtract 1990 from 2300, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 10:
3100 divided by 398 is 7 with a remainder of 314.
Use 7 as the next digit of our solution. 
Result so far: 249267.57
If we take 2786 away from 3100, we end up with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 11:
398 can be fit into 3140 7 times, resulting in a remainder of 354.
The number 7 becomes the next digit in our result. 
Result so far: 249267.577
Deduct 2786 from 3140 and we're left with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

After the division, we end up with 249267.577 and a remainder of 0.0354.
