355863 ÷ 99 
We want to figure out the number of times 355863 can be divided by 99.

Let's proceed to step 1:
The number 99 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 99

Advancing to step 2:
The number 99 fits into 35 0 times, leaving a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Grab the next digit (5) from the dividend, add it to 35, then carry on: 355 / 99

Advancing to step 3:
355 divided by 99 is 3 with a remainder of 58.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 297 away from 355, we end up with 58.
Fetch the next digit (8) from the dividend, attach it to 58 and continue: 588 / 99

Step 4:
99 can be fit into 588 5 times, resulting in a remainder of 93.
The next digit of our result is 5. 
Result so far: 35.0
The remainder is 93 after subtracting 495 from 588.
Fetch the next digit (6) from the dividend, attach it to 93 and continue: 936 / 99

Let's proceed to step 5:
If we divide 936 by 99, we get 9 and a remainder of 45.
The number 9 becomes the next digit in our result. 
Result so far: 359.0
Subtract 891 from 936 to get 45.
Bring next digit (3) of the dividend behind the 45 and repeat the process: 453 / 99

Step 6:
99 goes into 453 4 times with a remainder of 57.
Put 4 as the next digit of the answer. 
Result so far: 3594.0
The remainder is 57 after subtracting 396 from 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 7:
99 goes into 570 5 times with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 3594.5
If we take 495 away from 570, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 8:
The number 99 fits into 750 7 times, leaving a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 3594.57
If we take 693 away from 750, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 9:
570 divided by 99 is 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 3594.575
Subtract 495 from 570 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 10:
When dividing 750 by 99, we get 7 with a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 3594.5757
Subtracting 693 from 750 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 11:
When dividing 570 by 99, we get 5 with a remainder of 75.
The next digit of our result is 5. 
Result so far: 3594.57575
Deduct 495 from 570 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 12:
When dividing 750 by 99, we get 7 with a remainder of 57.
The next digit of our result is 7. 
Result so far: 3594.575757
If we take 693 away from 750, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 13:
99 goes into 570 5 times with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 3594.5757575
The remainder is 75 after subtracting 495 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 14:
The number 99 fits into 750 7 times, leaving a remainder of 57.
The next digit of our result is 7. 
Result so far: 3594.57575757
Deduct 693 from 750 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

The final outcome is 3594.57575757, with a leftover of 5.7e-08.
