We're dividing 440644 by 99 
We want to figure out the number of times 440644 can be divided by 99.

Step 1:
99 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 99

Step 2:
When dividing 44 by 99, we get 0 with a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 44, we get 44.
Bring next digit (0) of the dividend behind the 44 and repeat the process: 440 / 99

Going ahead to step 3:
If we divide 440 by 99, we get 4 and a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 396 from 440 to get 44.
Bring next digit (6) of the dividend behind the 44 and repeat the process: 446 / 99

Moving on to step 4:
99 can be fit into 446 4 times, resulting in a remainder of 50.
The next digit of our result is 4. 
Result so far: 44.0
The remainder is 50 after subtracting 396 from 446.
Fetch the next digit (4) from the dividend, attach it to 50 and continue: 504 / 99

Step 5:
If we divide 504 by 99, we get 5 and a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 445.0
Subtract 495 from 504 to get 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 99

Step 6:
If we divide 94 by 99, we get 0 and a remainder of 94.
The next digit of our result is 0. 
Result so far: 4450.0
Subtract 0 from 94 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 7:
If we divide 940 by 99, we get 9 and a remainder of 49.
The next digit of our result is 9. 
Result so far: 4450.9
Subtract 891 from 940 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 8:
490 divided by 99 is 4 with a remainder of 94.
The next digit of our result is 4. 
Result so far: 4450.94
If we subtract 396 from 490, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 9:
940 divided by 99 is 9 with a remainder of 49.
The next digit of our result is 9. 
Result so far: 4450.949
If we take 891 away from 940, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 10:
If we divide 490 by 99, we get 4 and a remainder of 94.
Write down 4 as next digit of the result. 
Result so far: 4450.9494
If we subtract 396 from 490, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 11:
99 goes into 940 9 times with a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 4450.94949
If we subtract 891 from 940, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 12:
When dividing 490 by 99, we get 4 with a remainder of 94.
Use 4 as the next digit of our solution. 
Result so far: 4450.949494
Deduct 396 from 490 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 13:
The number 99 fits into 940 9 times, leaving a remainder of 49.
The next digit of our result is 9. 
Result so far: 4450.9494949
Subtracting 891 from 940 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 14:
When dividing 490 by 99, we get 4 with a remainder of 94.
Use 4 as the next digit of our solution. 
Result so far: 4450.94949494
Deduct 396 from 490 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

The final outcome is 4450.94949494, with a leftover of 9.4e-08.
