We're dividing 910592 by 99 
The aim is to understand the frequency of 99 in 910592.

Step 1:
The number 99 fits into 9 0 times, leaving 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.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 99

Step 2:
91 divided by 99 is 0 with a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Append the next digit (0) from the dividend to 91 and continue with: 910 / 99

Going ahead to step 3:
99 goes into 910 9 times with a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 891 from 910 and we're left with 19.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 99

Moving on to step 4:
99 can be fit into 195 1 times, resulting in a remainder of 96.
The next digit of our result is 1. 
Result so far: 91.0
Deduct 99 from 195 and we're left with 96.
Include the next digit (9) from the dividend after 96, then repeat: 969 / 99

Advancing to step 5:
99 can be fit into 969 9 times, resulting in a remainder of 78.
Record the quotient 9 as the next digit in the result. 
Result so far: 919.0
The remainder is 78 after subtracting 891 from 969.
Append the next digit (2) from the dividend to 78 and continue with: 782 / 99

On to step 6:
99 goes into 782 7 times with a remainder of 89.
The number 7 becomes the next digit in our result. 
Result so far: 9197.0
Deduct 693 from 782 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 7:
890 divided by 99 is 8 with a remainder of 98.
The number 8 becomes the next digit in our result. 
Result so far: 9197.8
The remainder is 98 after subtracting 792 from 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 8:
When dividing 980 by 99, we get 9 with a remainder of 89.
The next digit of our result is 9. 
Result so far: 9197.89
If we subtract 891 from 980, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 9:
99 goes into 890 8 times with a remainder of 98.
Write down 8 as next digit of the result. 
Result so far: 9197.898
Subtracting 792 from 890 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 10:
980 divided by 99 is 9 with a remainder of 89.
Put 9 as the next digit of the answer. 
Result so far: 9197.8989
Subtract 891 from 980 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 11:
The number 99 fits into 890 8 times, leaving a remainder of 98.
Put 8 as the next digit of the answer. 
Result so far: 9197.89898
Deduct 792 from 890 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 12:
980 divided by 99 is 9 with a remainder of 89.
Write down 9 as next digit of the result. 
Result so far: 9197.898989
Subtract 891 from 980 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 13:
If we divide 890 by 99, we get 8 and a remainder of 98.
Record the quotient 8 as the next digit in the result. 
Result so far: 9197.8989898
Subtracting 792 from 890 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 14:
When dividing 980 by 99, we get 9 with a remainder of 89.
Use 9 as the next digit of our solution. 
Result so far: 9197.89898989
Deduct 891 from 980 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

The quotient of the division is 9197.89898989, and the remainder is 8.9e-08.
