We're dividing 890124 by 99 
The aim is to understand the frequency of 99 in 890124.

On to step 1:
When dividing 8 by 99, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 99

On to step 2:
99 can be fit into 89 0 times, resulting in a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Fetch the next digit (0) from the dividend, attach it to 89 and continue: 890 / 99

Moving on to step 3:
When dividing 890 by 99, we get 8 with a remainder of 98.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 792 from 890, we get 98.
Append the next digit (1) from the dividend to 98 and continue with: 981 / 99

On to step 4:
When dividing 981 by 99, we get 9 with a remainder of 90.
Write down 9 as next digit of the result. 
Result so far: 89.0
If we take 891 away from 981, we end up with 90.
Append the next digit (2) from the dividend to 90 and continue with: 902 / 99

Going ahead to step 5:
The number 99 fits into 902 9 times, leaving a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 899.0
If we subtract 891 from 902, we get 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 99

On to step 6:
If we divide 114 by 99, we get 1 and a remainder of 15.
The next digit of our result is 1. 
Result so far: 8991.0
Subtracting 99 from 114 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
If we divide 150 by 99, we get 1 and a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 8991.1
If we subtract 99 from 150, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 8:
The number 99 fits into 510 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 8991.15
Subtracting 495 from 510 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
150 divided by 99 is 1 with a remainder of 51.
Use 1 as the next digit of our solution. 
Result so far: 8991.151
Subtracting 99 from 150 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 10:
99 can be fit into 510 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 8991.1515
Deduct 495 from 510 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
If we divide 150 by 99, we get 1 and a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 8991.15151
Subtract 99 from 150 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 12:
The number 99 fits into 510 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 8991.151515
If we subtract 495 from 510, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 13:
The number 99 fits into 150 1 times, leaving a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 8991.1515151
If we subtract 99 from 150, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 14:
When dividing 510 by 99, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 8991.15151515
The remainder is 15 after subtracting 495 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 8991.15151515, and the remainder is 1.5e-08.
