Let's divide 415949 by 99
We want to figure out the number of times 415949 can be divided by 99.

Step 1:
When dividing 4 by 99, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 99

Advancing to step 2:
The number 99 fits into 41 0 times, leaving a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 41 and we're left with 41.
Bring next digit (5) of the dividend behind the 41 and repeat the process: 415 / 99

Step 3:
If we divide 415 by 99, we get 4 and a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 396 from 415, we get 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 99

Advancing to step 4:
The number 99 fits into 199 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 42.0
The remainder is 1 after subtracting 198 from 199.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 99

Going ahead to step 5:
99 can be fit into 14 0 times, resulting in a remainder of 14.
The next digit of our result is 0. 
Result so far: 420.0
If we subtract 0 from 14, we get 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 99

On to step 6:
99 can be fit into 149 1 times, resulting in a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 4201.0
Subtract 99 from 149 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 7:
If we divide 500 by 99, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 4201.5
Subtracting 495 from 500 leaves us 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.

Advancing to step 8:
If we divide 50 by 99, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 4201.5
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.

Going ahead to step 9:
When dividing 500 by 99, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 4201.505
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.

Let's proceed to step 10:
99 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 4201.505
If we take 0 away from 50, we end up 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 11:
When dividing 500 by 99, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 4201.50505
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.

Advancing to step 12:
99 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 4201.50505
If we take 0 away from 50, we end up 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.

Let's proceed to step 13:
500 divided by 99 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 4201.5050505
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 14:
50 divided by 99 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 4201.5050505
If we take 0 away from 50, we end up 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.

After the division, we end up with 4201.5050505 and a remainder of 5e-08.
