We look at the division of 965620 by 99 
The aim is to understand the frequency of 99 in 965620.

Moving on to step 1:
When dividing 9 by 99, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 99

Let's proceed to step 2:
The number 99 fits into 96 0 times, leaving a remainder of 96.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 96 and we're left with 96.
Bring next digit (5) of the dividend behind the 96 and repeat the process: 965 / 99

Let's proceed to step 3:
The number 99 fits into 965 9 times, leaving a remainder of 74.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 74 after subtracting 891 from 965.
Bring next digit (6) of the dividend behind the 74 and repeat the process: 746 / 99

Going ahead to step 4:
When dividing 746 by 99, we get 7 with a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 97.0
Subtract 693 from 746 to get 53.
Append the next digit (2) from the dividend to 53 and continue with: 532 / 99

On to step 5:
532 divided by 99 is 5 with a remainder of 37.
Put 5 as the next digit of the answer. 
Result so far: 975.0
If we subtract 495 from 532, we get 37.
Bring next digit (0) of the dividend behind the 37 and repeat the process: 370 / 99

On to step 6:
99 can be fit into 370 3 times, resulting in a remainder of 73.
The next digit of our result is 3. 
Result so far: 9753.0
Deduct 297 from 370 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 7:
730 divided by 99 is 7 with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 9753.7
If we take 693 away from 730, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 8:
When dividing 370 by 99, we get 3 with a remainder of 73.
The next digit of our result is 3. 
Result so far: 9753.73
If we take 297 away from 370, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 9:
The number 99 fits into 730 7 times, leaving a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 9753.737
Subtracting 693 from 730 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 10:
If we divide 370 by 99, we get 3 and a remainder of 73.
The next digit of our result is 3. 
Result so far: 9753.7373
Deduct 297 from 370 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 11:
When dividing 730 by 99, we get 7 with a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 9753.73737
Subtracting 693 from 730 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 12:
The number 99 fits into 370 3 times, leaving a remainder of 73.
Use 3 as the next digit of our solution. 
Result so far: 9753.737373
The remainder is 73 after subtracting 297 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 13:
The number 99 fits into 730 7 times, leaving a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 9753.7373737
Subtract 693 from 730 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 14:
If we divide 370 by 99, we get 3 and a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 9753.73737373
Subtract 297 from 370 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

The final result is 9753.73737373 with a remainder of 7.3e-08.
