Let's divide 647451 by 99
The aim is to understand the frequency of 99 in 647451.

Step 1:
99 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 99

On to step 2:
When dividing 64 by 99, we get 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Fetch the next digit (7) from the dividend, attach it to 64 and continue: 647 / 99

Going ahead to step 3:
When dividing 647 by 99, we get 6 with a remainder of 53.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 594 from 647, we get 53.
Take the next digit (4) from the dividend and append it to 53, then repeat: 534 / 99

Moving on to step 4:
If we divide 534 by 99, we get 5 and a remainder of 39.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
Deduct 495 from 534 and we're left with 39.
Append the next digit (5) from the dividend to 39 and continue with: 395 / 99

Moving on to step 5:
395 divided by 99 is 3 with a remainder of 98.
Record the quotient 3 as the next digit in the result. 
Result so far: 653.0
Deduct 297 from 395 and we're left with 98.
Fetch the next digit (1) from the dividend, attach it to 98 and continue: 981 / 99

Moving on to step 6:
981 divided by 99 is 9 with a remainder of 90.
The next digit of our result is 9. 
Result so far: 6539.0
The remainder is 90 after subtracting 891 from 981.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 7:
If we divide 900 by 99, we get 9 and a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 6539.9
If we take 891 away from 900, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
The number 99 fits into 90 0 times, leaving a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 6539.9
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 9:
The number 99 fits into 900 9 times, leaving a remainder of 9.
The next digit of our result is 9. 
Result so far: 6539.909
Deduct 891 from 900 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 10:
The number 99 fits into 90 0 times, leaving a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 6539.909
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 11:
When dividing 900 by 99, we get 9 with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 6539.90909
Subtracting 891 from 900 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 12:
If we divide 90 by 99, we get 0 and a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 6539.90909
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 13:
99 can be fit into 900 9 times, resulting in a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 6539.9090909
Deduct 891 from 900 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 14:
When dividing 90 by 99, we get 0 with a remainder of 90.
The next digit of our result is 0. 
Result so far: 6539.9090909
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The final result is 6539.9090909 with a remainder of 9e-08.
