We look at the division of 251703 by 99 
The aim is to understand the frequency of 99 in 251703.

On to step 1:
If we divide 2 by 99, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 99

Let's proceed to step 2:
25 divided by 99 is 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Append the next digit (1) from the dividend to 25 and continue with: 251 / 99

Step 3:
99 goes into 251 2 times with a remainder of 53.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 198 from 251, we get 53.
Append the next digit (7) from the dividend to 53 and continue with: 537 / 99

Step 4:
If we divide 537 by 99, we get 5 and a remainder of 42.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtract 495 from 537 to get 42.
Fetch the next digit (0) from the dividend, attach it to 42 and continue: 420 / 99

On to step 5:
If we divide 420 by 99, we get 4 and a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 254.0
Subtracting 396 from 420 leaves us with 24.
Take the next digit (3) from the dividend and append it to 24, then repeat: 243 / 99

Let's proceed to step 6:
243 divided by 99 is 2 with a remainder of 45.
Write down 2 as next digit of the result. 
Result so far: 2542.0
Subtracting 198 from 243 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 7:
The number 99 fits into 450 4 times, leaving a remainder of 54.
The next digit of our result is 4. 
Result so far: 2542.4
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.

On to step 8:
99 goes into 540 5 times with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 2542.45
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 9:
450 divided by 99 is 4 with a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 2542.454
Subtract 396 from 450 to 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.

Step 10:
99 can be fit into 540 5 times, resulting in a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 2542.4545
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.

On to step 11:
The number 99 fits into 450 4 times, leaving a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 2542.45454
Subtract 396 from 450 to 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.

Step 12:
If we divide 540 by 99, we get 5 and a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 2542.454545
Subtract 495 from 540 to 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.

Let's proceed to step 13:
The number 99 fits into 450 4 times, leaving a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 2542.4545454
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.

Going ahead to step 14:
99 can be fit into 540 5 times, resulting in a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 2542.45454545
Deduct 495 from 540 and we're left 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.

The quotient of the division is 2542.45454545, and the remainder is 4.5e-08.
