455999 ÷ 99 
Let's see how many times 99 fits into 455999.

Going ahead to step 1:
If we divide 4 by 99, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 99

Let's proceed to step 2:
99 goes into 45 0 times with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Fetch the next digit (5) from the dividend, attach it to 45 and continue: 455 / 99

Moving on to step 3:
455 divided by 99 is 4 with a remainder of 59.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 59 after subtracting 396 from 455.
Include the next digit (9) from the dividend after 59, then repeat: 599 / 99

On to step 4:
99 can be fit into 599 6 times, resulting in a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 46.0
Subtracting 594 from 599 leaves us with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 99

Let's proceed to step 5:
99 goes into 59 0 times with a remainder of 59.
Use 0 as the next digit of our solution. 
Result so far: 460.0
Subtracting 0 from 59 leaves us with 59.
Append the next digit (9) from the dividend to 59 and continue with: 599 / 99

On to step 6:
When dividing 599 by 99, we get 6 with a remainder of 5.
The next digit of our result is 6. 
Result so far: 4606.0
The remainder is 5 after subtracting 594 from 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
If we divide 50 by 99, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 4606.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
500 divided by 99 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 4606.05
Deduct 495 from 500 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
50 divided by 99 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 4606.05
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
99 can be fit into 500 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 4606.0505
If we take 495 away from 500, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 11:
If we divide 50 by 99, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 4606.0505
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
If we divide 500 by 99, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 4606.050505
Subtract 495 from 500 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 13:
The number 99 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 4606.050505
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 14:
99 goes into 500 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 4606.05050505
If we subtract 495 from 500, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 4606.05050505 and a remainder of 5e-09.
