Let's divide 811993 by 99
The aim is to understand the frequency of 99 in 811993.

Step 1:
99 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 99

Let's proceed to step 2:
81 divided by 99 is 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Fetch the next digit (1) from the dividend, attach it to 81 and continue: 811 / 99

Let's proceed to step 3:
99 can be fit into 811 8 times, resulting in a remainder of 19.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 792 from 811, we get 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 99

Advancing to step 4:
199 divided by 99 is 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
If we take 198 away from 199, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 99

On to step 5:
The number 99 fits into 19 0 times, leaving a remainder of 19.
The next digit of our result is 0. 
Result so far: 820.0
The remainder is 19 after subtracting 0 from 19.
Append the next digit (3) from the dividend to 19 and continue with: 193 / 99

Advancing to step 6:
99 goes into 193 1 times with a remainder of 94.
Put 1 as the next digit of the answer. 
Result so far: 8201.0
Deduct 99 from 193 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 7:
940 divided by 99 is 9 with a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 8201.9
Subtracting 891 from 940 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 8:
99 goes into 490 4 times with a remainder of 94.
The next digit of our result is 4. 
Result so far: 8201.94
Subtracting 396 from 490 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 9:
99 goes into 940 9 times with a remainder of 49.
The next digit of our result is 9. 
Result so far: 8201.949
Subtracting 891 from 940 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 10:
If we divide 490 by 99, we get 4 and a remainder of 94.
Use 4 as the next digit of our solution. 
Result so far: 8201.9494
If we take 396 away from 490, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 11:
When dividing 940 by 99, we get 9 with a remainder of 49.
The next digit of our result is 9. 
Result so far: 8201.94949
If we take 891 away from 940, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 12:
If we divide 490 by 99, we get 4 and a remainder of 94.
Put 4 as the next digit of the answer. 
Result so far: 8201.949494
Deduct 396 from 490 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 13:
940 divided by 99 is 9 with a remainder of 49.
Use 9 as the next digit of our solution. 
Result so far: 8201.9494949
Subtract 891 from 940 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 14:
The number 99 fits into 490 4 times, leaving a remainder of 94.
Use 4 as the next digit of our solution. 
Result so far: 8201.94949494
The remainder is 94 after subtracting 396 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

The quotient of the division is 8201.94949494, and the remainder is 9.4e-08.
