989657 ÷ 99 
The aim is to understand the frequency of 99 in 989657.

Moving on to step 1:
9 divided by 99 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 99

Step 2:
When dividing 98 by 99, we get 0 with a remainder of 98.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Append the next digit (9) from the dividend to 98 and continue with: 989 / 99

Moving on to step 3:
99 can be fit into 989 9 times, resulting in a remainder of 98.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 891 from 989 to get 98.
Fetch the next digit (6) from the dividend, attach it to 98 and continue: 986 / 99

Moving on to step 4:
When dividing 986 by 99, we get 9 with a remainder of 95.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
Subtract 891 from 986 to get 95.
Include the next digit (5) from the dividend after 95, then repeat: 955 / 99

Moving on to step 5:
If we divide 955 by 99, we get 9 and a remainder of 64.
The number 9 becomes the next digit in our result. 
Result so far: 999.0
Subtract 891 from 955 to get 64.
Grab the next digit (7) from the dividend, add it to 64, then carry on: 647 / 99

Step 6:
99 goes into 647 6 times with a remainder of 53.
Use 6 as the next digit of our solution. 
Result so far: 9996.0
Subtracting 594 from 647 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 7:
530 divided by 99 is 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 9996.5
Subtract 495 from 530 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 8:
When dividing 350 by 99, we get 3 with a remainder of 53.
Put 3 as the next digit of the answer. 
Result so far: 9996.53
The remainder is 53 after subtracting 297 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 9:
When dividing 530 by 99, we get 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 9996.535
If we subtract 495 from 530, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 10:
350 divided by 99 is 3 with a remainder of 53.
Record the quotient 3 as the next digit in the result. 
Result so far: 9996.5353
The remainder is 53 after subtracting 297 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 11:
The number 99 fits into 530 5 times, leaving a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 9996.53535
Deduct 495 from 530 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 12:
99 can be fit into 350 3 times, resulting in a remainder of 53.
Use 3 as the next digit of our solution. 
Result so far: 9996.535353
Subtracting 297 from 350 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 13:
99 goes into 530 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 9996.5353535
If we subtract 495 from 530, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 14:
99 can be fit into 350 3 times, resulting in a remainder of 53.
Use 3 as the next digit of our solution. 
Result so far: 9996.53535353
Subtracting 297 from 350 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The final result is 9996.53535353 with a remainder of 5.3e-08.
