We look at the division of 49557 by 99 
The aim is to understand the frequency of 99 in 49557.

Step 1:
When dividing 4 by 99, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 99

Moving on to step 2:
The number 99 fits into 49 0 times, leaving a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Grab the next digit (5) from the dividend, add it to 49, then carry on: 495 / 99

On to step 3:
495 divided by 99 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 495 away from 495, we end up with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 99

Step 4:
5 divided by 99 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 50.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 99

On to step 5:
If we divide 57 by 99, we get 0 and a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 500.0
Subtracting 0 from 57 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.

Advancing to step 6:
99 can be fit into 570 5 times, resulting in a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 500.5
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 7:
If we divide 750 by 99, we get 7 and a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 500.57
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.

Advancing to step 8:
99 goes into 570 5 times with a remainder of 75.
The next digit of our result is 5. 
Result so far: 500.575
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.

Moving on to step 9:
750 divided by 99 is 7 with a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 500.5757
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.

On to step 10:
99 goes into 570 5 times with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 500.57575
Subtracting 495 from 570 leaves us 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.

Step 11:
If we divide 750 by 99, we get 7 and a remainder of 57.
Put 7 as the next digit of the answer. 
Result so far: 500.575757
Subtract 693 from 750 to get 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 12:
99 goes into 570 5 times with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 500.5757575
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.

Let's proceed to step 13:
99 goes into 750 7 times with a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 500.57575757
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.

The quotient of the division is 500.57575757, and the remainder is 5.7e-08.
