Let's divide 78502 by 99
The aim is to understand the frequency of 99 in 78502.

Step 1:
99 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 99

Advancing to step 2:
The number 99 fits into 78 0 times, leaving a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (5) from the dividend, add it to 78, then carry on: 785 / 99

Advancing to step 3:
If we divide 785 by 99, we get 7 and a remainder of 92.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 693 away from 785, we end up with 92.
Grab the next digit (0) from the dividend, add it to 92, then carry on: 920 / 99

Let's proceed to step 4:
99 goes into 920 9 times with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 79.0
If we subtract 891 from 920, we get 29.
Append the next digit (2) from the dividend to 29 and continue with: 292 / 99

Step 5:
The number 99 fits into 292 2 times, leaving a remainder of 94.
Use 2 as the next digit of our solution. 
Result so far: 792.0
Subtracting 198 from 292 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.

Moving on to step 6:
99 goes into 940 9 times with a remainder of 49.
The next digit of our result is 9. 
Result so far: 792.9
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.

Step 7:
99 can be fit into 490 4 times, resulting in a remainder of 94.
The next digit of our result is 4. 
Result so far: 792.94
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.

Advancing to step 8:
If we divide 940 by 99, we get 9 and a remainder of 49.
Use 9 as the next digit of our solution. 
Result so far: 792.949
The remainder is 49 after subtracting 891 from 940.
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 9:
If we divide 490 by 99, we get 4 and a remainder of 94.
Record the quotient 4 as the next digit in the result. 
Result so far: 792.9494
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.

Step 10:
The number 99 fits into 940 9 times, leaving a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 792.94949
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.

Moving on to step 11:
99 goes into 490 4 times with a remainder of 94.
Record the quotient 4 as the next digit in the result. 
Result so far: 792.949494
If we subtract 396 from 490, we get 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 12:
99 can be fit into 940 9 times, resulting in a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 792.9494949
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.

Step 13:
99 can be fit into 490 4 times, resulting in a remainder of 94.
The next digit of our result is 4. 
Result so far: 792.94949494
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.

In conclusion, the division gives 792.94949494 with a balance of 9.4e-08.
