566231 divided by 99 
The aim is to understand the frequency of 99 in 566231.

On to step 1:
If we divide 5 by 99, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 99

Let's proceed to step 2:
56 divided by 99 is 0 with a remainder of 56.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 56 after subtracting 0 from 56.
Bring next digit (6) of the dividend behind the 56 and repeat the process: 566 / 99

Advancing to step 3:
The number 99 fits into 566 5 times, leaving a remainder of 71.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 495 from 566, we get 71.
Take the next digit (2) from the dividend and append it to 71, then repeat: 712 / 99

Let's proceed to step 4:
99 goes into 712 7 times with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
Subtracting 693 from 712 leaves us with 19.
Append the next digit (3) from the dividend to 19 and continue with: 193 / 99

Going ahead to step 5:
193 divided by 99 is 1 with a remainder of 94.
Record the quotient 1 as the next digit in the result. 
Result so far: 571.0
If we take 99 away from 193, we end up with 94.
Take the next digit (1) from the dividend and append it to 94, then repeat: 941 / 99

Going ahead to step 6:
99 can be fit into 941 9 times, resulting in a remainder of 50.
The next digit of our result is 9. 
Result so far: 5719.0
Subtract 891 from 941 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 7:
99 can be fit into 500 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 5719.5
If we take 495 away from 500, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
99 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 5719.5
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
The number 99 fits into 500 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 5719.505
Subtracting 495 from 500 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
50 divided by 99 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 5719.505
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
500 divided by 99 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 5719.50505
If we take 495 away from 500, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 12:
The number 99 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 5719.50505
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 13:
500 divided by 99 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 5719.5050505
Subtract 495 from 500 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 14:
50 divided by 99 is 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 5719.5050505
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 5719.5050505 with a remainder of 5e-08.
