133251 divided by 99 
The aim is to understand the frequency of 99 in 133251.

Step 1:
If we divide 1 by 99, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 99

Step 2:
When dividing 13 by 99, we get 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 99

On to step 3:
99 can be fit into 133 1 times, resulting in a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 99 from 133 to get 34.
Fetch the next digit (2) from the dividend, attach it to 34 and continue: 342 / 99

Let's proceed to step 4:
The number 99 fits into 342 3 times, leaving a remainder of 45.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 297 from 342 and we're left with 45.
Take the next digit (5) from the dividend and append it to 45, then repeat: 455 / 99

Going ahead to step 5:
The number 99 fits into 455 4 times, leaving a remainder of 59.
The next digit of our result is 4. 
Result so far: 134.0
Deduct 396 from 455 and we're left with 59.
Fetch the next digit (1) from the dividend, attach it to 59 and continue: 591 / 99

On to step 6:
591 divided by 99 is 5 with a remainder of 96.
Record the quotient 5 as the next digit in the result. 
Result so far: 1345.0
If we take 495 away from 591, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 7:
99 goes into 960 9 times with a remainder of 69.
Record the quotient 9 as the next digit in the result. 
Result so far: 1345.9
Subtracting 891 from 960 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 8:
The number 99 fits into 690 6 times, leaving a remainder of 96.
Record the quotient 6 as the next digit in the result. 
Result so far: 1345.96
Deduct 594 from 690 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 9:
If we divide 960 by 99, we get 9 and a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 1345.969
Subtracting 891 from 960 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 10:
99 goes into 690 6 times with a remainder of 96.
Record the quotient 6 as the next digit in the result. 
Result so far: 1345.9696
Deduct 594 from 690 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 11:
99 can be fit into 960 9 times, resulting in a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 1345.96969
If we subtract 891 from 960, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 12:
99 goes into 690 6 times with a remainder of 96.
Record the quotient 6 as the next digit in the result. 
Result so far: 1345.969696
The remainder is 96 after subtracting 594 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 13:
The number 99 fits into 960 9 times, leaving a remainder of 69.
Write down 9 as next digit of the result. 
Result so far: 1345.9696969
If we subtract 891 from 960, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 14:
99 goes into 690 6 times with a remainder of 96.
Use 6 as the next digit of our solution. 
Result so far: 1345.96969696
Subtract 594 from 690 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The quotient of the division is 1345.96969696, and the remainder is 9.6e-08.
