We're dividing 64266 by 99 
The aim is to understand the frequency of 99 in 64266.

Step 1:
6 divided by 99 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 99

Moving on to step 2:
64 divided by 99 is 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Bring next digit (2) of the dividend behind the 64 and repeat the process: 642 / 99

Let's proceed to step 3:
99 can be fit into 642 6 times, resulting in a remainder of 48.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 594 from 642 and we're left with 48.
Include the next digit (6) from the dividend after 48, then repeat: 486 / 99

Let's proceed to step 4:
486 divided by 99 is 4 with a remainder of 90.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
If we take 396 away from 486, we end up with 90.
Include the next digit (6) from the dividend after 90, then repeat: 906 / 99

Moving on to step 5:
906 divided by 99 is 9 with a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 649.0
Deduct 891 from 906 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 6:
If we divide 150 by 99, we get 1 and a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 649.1
If we subtract 99 from 150, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 7:
99 can be fit into 510 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 649.15
Subtract 495 from 510 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
If we divide 150 by 99, we get 1 and a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 649.151
If we take 99 away from 150, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 9:
When dividing 510 by 99, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 649.1515
The remainder is 15 after subtracting 495 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
When dividing 150 by 99, we get 1 with a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 649.15151
If we subtract 99 from 150, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 11:
If we divide 510 by 99, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 649.151515
Subtract 495 from 510 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 12:
The number 99 fits into 150 1 times, leaving a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 649.1515151
Deduct 99 from 150 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 13:
99 can be fit into 510 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 649.15151515
Subtract 495 from 510 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 649.15151515, and the remainder is 1.5e-08.
