431149 ÷ 99 
Let's see how many times 99 fits into 431149.

Moving on to step 1:
The number 99 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 99

Step 2:
The number 99 fits into 43 0 times, leaving a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Grab the next digit (1) from the dividend, add it to 43, then carry on: 431 / 99

Let's proceed to step 3:
The number 99 fits into 431 4 times, leaving a remainder of 35.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 396 from 431, we get 35.
Fetch the next digit (1) from the dividend, attach it to 35 and continue: 351 / 99

Step 4:
When dividing 351 by 99, we get 3 with a remainder of 54.
The next digit of our result is 3. 
Result so far: 43.0
Subtract 297 from 351 to get 54.
Append the next digit (4) from the dividend to 54 and continue with: 544 / 99

Moving on to step 5:
If we divide 544 by 99, we get 5 and a remainder of 49.
Write down 5 as next digit of the result. 
Result so far: 435.0
If we subtract 495 from 544, we get 49.
Fetch the next digit (9) from the dividend, attach it to 49 and continue: 499 / 99

Let's proceed to step 6:
When dividing 499 by 99, we get 5 with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 4355.0
The remainder is 4 after subtracting 495 from 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
When dividing 40 by 99, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 4355.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
400 divided by 99 is 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 4355.04
Subtracting 396 from 400 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
99 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 4355.04
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
The number 99 fits into 400 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 4355.0404
Deduct 396 from 400 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
The number 99 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 4355.0404
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
400 divided by 99 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 4355.040404
If we subtract 396 from 400, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
The number 99 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 4355.040404
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
99 goes into 400 4 times with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 4355.04040404
If we subtract 396 from 400, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 4355.04040404, and the remainder is 4e-09.
