Let's divide 88861 by 99
The aim is to understand the frequency of 99 in 88861.

Advancing to step 1:
The number 99 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 99

On to step 2:
If we divide 88 by 99, we get 0 and a remainder of 88.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 88, we get 88.
Append the next digit (8) from the dividend to 88 and continue with: 888 / 99

Let's proceed to step 3:
If we divide 888 by 99, we get 8 and a remainder of 96.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 792 from 888 to get 96.
Take the next digit (6) from the dividend and append it to 96, then repeat: 966 / 99

Let's proceed to step 4:
966 divided by 99 is 9 with a remainder of 75.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
Deduct 891 from 966 and we're left with 75.
Include the next digit (1) from the dividend after 75, then repeat: 751 / 99

Let's proceed to step 5:
751 divided by 99 is 7 with a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 897.0
Subtracting 693 from 751 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 6:
If we divide 580 by 99, we get 5 and a remainder of 85.
The next digit of our result is 5. 
Result so far: 897.5
Subtract 495 from 580 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 7:
When dividing 850 by 99, we get 8 with a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 897.58
Subtracting 792 from 850 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 8:
If we divide 580 by 99, we get 5 and a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 897.585
Deduct 495 from 580 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 9:
If we divide 850 by 99, we get 8 and a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 897.5858
Deduct 792 from 850 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 10:
99 can be fit into 580 5 times, resulting in a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 897.58585
If we subtract 495 from 580, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 11:
If we divide 850 by 99, we get 8 and a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 897.585858
Deduct 792 from 850 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 12:
580 divided by 99 is 5 with a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 897.5858585
If we subtract 495 from 580, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 13:
If we divide 850 by 99, we get 8 and a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 897.58585858
Deduct 792 from 850 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

After the division, we end up with 897.58585858 and a remainder of 5.8e-08.
