Let's divide 261900 by 99
The aim is to understand the frequency of 99 in 261900.

On to step 1:
The number 99 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 99

Moving on to step 2:
If we divide 26 by 99, we get 0 and a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 26, we end up with 26.
Grab the next digit (1) from the dividend, add it to 26, then carry on: 261 / 99

Let's proceed to step 3:
When dividing 261 by 99, we get 2 with a remainder of 63.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 198 from 261 leaves us with 63.
Fetch the next digit (9) from the dividend, attach it to 63 and continue: 639 / 99

Let's proceed to step 4:
When dividing 639 by 99, we get 6 with a remainder of 45.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
Subtracting 594 from 639 leaves us with 45.
Grab the next digit (0) from the dividend, add it to 45, then carry on: 450 / 99

On to step 5:
450 divided by 99 is 4 with a remainder of 54.
The next digit of our result is 4. 
Result so far: 264.0
Subtracting 396 from 450 leaves us with 54.
Take the next digit (0) from the dividend and append it to 54, then repeat: 540 / 99

On to step 6:
99 goes into 540 5 times with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 2645.0
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.

Moving on to step 7:
450 divided by 99 is 4 with a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 2645.4
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.

Advancing to step 8:
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: 2645.45
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.

Let's proceed to step 9:
When dividing 450 by 99, we get 4 with a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 2645.454
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.

Going ahead to 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: 2645.4545
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 11:
99 can be fit into 450 4 times, resulting in a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 2645.45454
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.

Step 12:
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: 2645.454545
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.

Moving on to step 13:
The number 99 fits into 450 4 times, leaving a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 2645.4545454
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.

Step 14:
540 divided by 99 is 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 2645.45454545
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.

In conclusion, the division gives 2645.45454545 with a balance of 4.5e-08.
