We look at the division of 250425 by 99 
The aim is to understand the frequency of 99 in 250425.

Let's proceed to step 1:
2 divided by 99 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 99

Moving on to step 2:
25 divided by 99 is 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Grab the next digit (0) from the dividend, add it to 25, then carry on: 250 / 99

Let's proceed to step 3:
If we divide 250 by 99, we get 2 and a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 198 from 250 and we're left with 52.
Append the next digit (4) from the dividend to 52 and continue with: 524 / 99

Moving on to step 4:
If we divide 524 by 99, we get 5 and a remainder of 29.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Deduct 495 from 524 and we're left with 29.
Grab the next digit (2) from the dividend, add it to 29, then carry on: 292 / 99

Step 5:
99 can be fit into 292 2 times, resulting in a remainder of 94.
Use 2 as the next digit of our solution. 
Result so far: 252.0
Deduct 198 from 292 and we're left with 94.
Append the next digit (5) from the dividend to 94 and continue with: 945 / 99

Step 6:
99 can be fit into 945 9 times, resulting in a remainder of 54.
Use 9 as the next digit of our solution. 
Result so far: 2529.0
The remainder is 54 after subtracting 891 from 945.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 7:
99 goes into 540 5 times with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 2529.5
If we subtract 495 from 540, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 8:
The number 99 fits into 450 4 times, leaving a remainder of 54.
Write down 4 as next digit of the result. 
Result so far: 2529.54
If we subtract 396 from 450, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 9:
99 goes into 540 5 times with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 2529.545
Subtracting 495 from 540 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 10:
450 divided by 99 is 4 with a remainder of 54.
Write down 4 as next digit of the result. 
Result so far: 2529.5454
Deduct 396 from 450 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 11:
When dividing 540 by 99, we get 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 2529.54545
The remainder is 45 after subtracting 495 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 12:
450 divided by 99 is 4 with a remainder of 54.
Write down 4 as next digit of the result. 
Result so far: 2529.545454
Subtracting 396 from 450 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 13:
When dividing 540 by 99, we get 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 2529.5454545
The remainder is 45 after subtracting 495 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 14:
450 divided by 99 is 4 with a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 2529.54545454
If we take 396 away from 450, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The quotient of the division is 2529.54545454, and the remainder is 5.4e-08.
