491792 ÷ 99 
The aim is to understand the frequency of 99 in 491792.

Advancing to 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
Subtract 0 from 4 to get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 99

On to step 2:
If we divide 49 by 99, we get 0 and a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 49, we end up with 49.
Grab the next digit (1) from the dividend, add it to 49, then carry on: 491 / 99

Advancing to step 3:
If we divide 491 by 99, we get 4 and a remainder of 95.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 95 after subtracting 396 from 491.
Bring next digit (7) of the dividend behind the 95 and repeat the process: 957 / 99

Moving on to step 4:
957 divided by 99 is 9 with a remainder of 66.
Write down 9 as next digit of the result. 
Result so far: 49.0
If we take 891 away from 957, we end up with 66.
Fetch the next digit (9) from the dividend, attach it to 66 and continue: 669 / 99

Going ahead to step 5:
If we divide 669 by 99, we get 6 and a remainder of 75.
The next digit of our result is 6. 
Result so far: 496.0
Subtracting 594 from 669 leaves us with 75.
Bring next digit (2) of the dividend behind the 75 and repeat the process: 752 / 99

Let's proceed to step 6:
When dividing 752 by 99, we get 7 with a remainder of 59.
The next digit of our result is 7. 
Result so far: 4967.0
Subtract 693 from 752 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 7:
The number 99 fits into 590 5 times, leaving a remainder of 95.
Use 5 as the next digit of our solution. 
Result so far: 4967.5
Subtract 495 from 590 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 8:
99 goes into 950 9 times with a remainder of 59.
The next digit of our result is 9. 
Result so far: 4967.59
Deduct 891 from 950 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 9:
If we divide 590 by 99, we get 5 and a remainder of 95.
Record the quotient 5 as the next digit in the result. 
Result so far: 4967.595
The remainder is 95 after subtracting 495 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 10:
When dividing 950 by 99, we get 9 with a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 4967.5959
Subtracting 891 from 950 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 11:
99 can be fit into 590 5 times, resulting in a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 4967.59595
Subtract 495 from 590 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 12:
99 goes into 950 9 times with a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 4967.595959
The remainder is 59 after subtracting 891 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 13:
When dividing 590 by 99, we get 5 with a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 4967.5959595
Deduct 495 from 590 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 14:
When dividing 950 by 99, we get 9 with a remainder of 59.
The next digit of our result is 9. 
Result so far: 4967.59595959
If we subtract 891 from 950, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

The quotient of the division is 4967.59595959, and the remainder is 5.9e-08.
