We're dividing 647540 by 99 
The aim is to understand the frequency of 99 in 647540.

On to step 1:
6 divided by 99 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 99

Step 2:
99 goes into 64 0 times with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Include the next digit (7) from the dividend after 64, then repeat: 647 / 99

Advancing to step 3:
99 goes into 647 6 times with a remainder of 53.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 594 from 647 and we're left with 53.
Grab the next digit (5) from the dividend, add it to 53, then carry on: 535 / 99

Step 4:
99 goes into 535 5 times with a remainder of 40.
The next digit of our result is 5. 
Result so far: 65.0
If we take 495 away from 535, we end up with 40.
Take the next digit (4) from the dividend and append it to 40, then repeat: 404 / 99

Advancing to step 5:
The number 99 fits into 404 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 654.0
Deduct 396 from 404 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 99

On to step 6:
99 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 6540.0
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 7:
If we divide 800 by 99, we get 8 and a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 6540.8
If we take 792 away from 800, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
When dividing 80 by 99, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 6540.8
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 9:
800 divided by 99 is 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 6540.808
Deduct 792 from 800 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
80 divided by 99 is 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 6540.808
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 11:
800 divided by 99 is 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 6540.80808
If we take 792 away from 800, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
99 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 6540.80808
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 13:
99 can be fit into 800 8 times, resulting in a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 6540.8080808
If we take 792 away from 800, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
99 goes into 80 0 times with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 6540.8080808
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 6540.8080808 with a remaining 8e-08.
