We're dividing 576841 by 99 
The aim is to understand the frequency of 99 in 576841.

Step 1:
5 divided by 99 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 99

Going ahead to step 2:
57 divided by 99 is 0 with a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Append the next digit (6) from the dividend to 57 and continue with: 576 / 99

Step 3:
When dividing 576 by 99, we get 5 with a remainder of 81.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 495 from 576, we get 81.
Take the next digit (8) from the dividend and append it to 81, then repeat: 818 / 99

Moving on to step 4:
If we divide 818 by 99, we get 8 and a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 58.0
Subtract 792 from 818 to get 26.
Grab the next digit (4) from the dividend, add it to 26, then carry on: 264 / 99

Let's proceed to step 5:
The number 99 fits into 264 2 times, leaving a remainder of 66.
The next digit of our result is 2. 
Result so far: 582.0
Deduct 198 from 264 and we're left with 66.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 99

Going ahead to step 6:
When dividing 661 by 99, we get 6 with a remainder of 67.
The next digit of our result is 6. 
Result so far: 5826.0
Subtract 594 from 661 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 7:
The number 99 fits into 670 6 times, leaving a remainder of 76.
Use 6 as the next digit of our solution. 
Result so far: 5826.6
The remainder is 76 after subtracting 594 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 8:
760 divided by 99 is 7 with a remainder of 67.
Use 7 as the next digit of our solution. 
Result so far: 5826.67
If we subtract 693 from 760, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 9:
99 goes into 670 6 times with a remainder of 76.
The number 6 becomes the next digit in our result. 
Result so far: 5826.676
Deduct 594 from 670 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 10:
99 can be fit into 760 7 times, resulting in a remainder of 67.
Use 7 as the next digit of our solution. 
Result so far: 5826.6767
If we take 693 away from 760, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 11:
When dividing 670 by 99, we get 6 with a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 5826.67676
Subtracting 594 from 670 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 12:
99 can be fit into 760 7 times, resulting in a remainder of 67.
Put 7 as the next digit of the answer. 
Result so far: 5826.676767
Subtract 693 from 760 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 13:
99 goes into 670 6 times with a remainder of 76.
The number 6 becomes the next digit in our result. 
Result so far: 5826.6767676
If we take 594 away from 670, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 14:
99 goes into 760 7 times with a remainder of 67.
Record the quotient 7 as the next digit in the result. 
Result so far: 5826.67676767
Deduct 693 from 760 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

After the division, we end up with 5826.67676767 and a remainder of 6.7e-08.
