We look at the division of 726331 by 99 
The aim is to understand the frequency of 99 in 726331.

Moving on to step 1:
If we divide 7 by 99, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 99

Step 2:
If we divide 72 by 99, we get 0 and a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Bring next digit (6) of the dividend behind the 72 and repeat the process: 726 / 99

Advancing to step 3:
When dividing 726 by 99, we get 7 with a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 693 from 726 to get 33.
Include the next digit (3) from the dividend after 33, then repeat: 333 / 99

Step 4:
99 can be fit into 333 3 times, resulting in a remainder of 36.
Use 3 as the next digit of our solution. 
Result so far: 73.0
Subtracting 297 from 333 leaves us with 36.
Fetch the next digit (3) from the dividend, attach it to 36 and continue: 363 / 99

Advancing to step 5:
99 goes into 363 3 times with a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 733.0
The remainder is 66 after subtracting 297 from 363.
Append the next digit (1) from the dividend to 66 and continue with: 661 / 99

Moving on to step 6:
99 goes into 661 6 times with a remainder of 67.
Put 6 as the next digit of the answer. 
Result so far: 7336.0
If we subtract 594 from 661, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 7:
670 divided by 99 is 6 with a remainder of 76.
Record the quotient 6 as the next digit in the result. 
Result so far: 7336.6
The remainder is 76 after subtracting 594 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 8:
When dividing 760 by 99, we get 7 with a remainder of 67.
Record the quotient 7 as the next digit in the result. 
Result so far: 7336.67
Subtract 693 from 760 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 9:
99 goes into 670 6 times with a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 7336.676
Subtract 594 from 670 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 10:
If we divide 760 by 99, we get 7 and a remainder of 67.
Use 7 as the next digit of our solution. 
Result so far: 7336.6767
The remainder is 67 after subtracting 693 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 11:
99 can be fit into 670 6 times, resulting in a remainder of 76.
Use 6 as the next digit of our solution. 
Result so far: 7336.67676
Subtract 594 from 670 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 12:
The number 99 fits into 760 7 times, leaving a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 7336.676767
Subtracting 693 from 760 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 13:
If we divide 670 by 99, we get 6 and a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 7336.6767676
Subtracting 594 from 670 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 14:
If we divide 760 by 99, we get 7 and a remainder of 67.
The next digit of our result is 7. 
Result so far: 7336.67676767
If we take 693 away from 760, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Our division results in 7336.67676767 with a remaining 6.7e-08.
