Let's divide 782971 by 99
The aim is to understand the frequency of 99 in 782971.

Moving on to step 1:
When dividing 7 by 99, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 99

Going ahead to step 2:
If we divide 78 by 99, we get 0 and a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Include the next digit (2) from the dividend after 78, then repeat: 782 / 99

Advancing to step 3:
If we divide 782 by 99, we get 7 and a remainder of 89.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 693 away from 782, we end up with 89.
Include the next digit (9) from the dividend after 89, then repeat: 899 / 99

Moving on to step 4:
899 divided by 99 is 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 79.0
The remainder is 8 after subtracting 891 from 899.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 99

Let's proceed to step 5:
87 divided by 99 is 0 with a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 790.0
The remainder is 87 after subtracting 0 from 87.
Take the next digit (1) from the dividend and append it to 87, then repeat: 871 / 99

Moving on to step 6:
99 goes into 871 8 times with a remainder of 79.
The number 8 becomes the next digit in our result. 
Result so far: 7908.0
Deduct 792 from 871 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 7:
99 goes into 790 7 times with a remainder of 97.
Use 7 as the next digit of our solution. 
Result so far: 7908.7
If we subtract 693 from 790, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Advancing to step 8:
When dividing 970 by 99, we get 9 with a remainder of 79.
Put 9 as the next digit of the answer. 
Result so far: 7908.79
If we subtract 891 from 970, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 9:
If we divide 790 by 99, we get 7 and a remainder of 97.
Write down 7 as next digit of the result. 
Result so far: 7908.797
The remainder is 97 after subtracting 693 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Moving on to step 10:
99 goes into 970 9 times with a remainder of 79.
Record the quotient 9 as the next digit in the result. 
Result so far: 7908.7979
Subtracting 891 from 970 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 11:
99 goes into 790 7 times with a remainder of 97.
Put 7 as the next digit of the answer. 
Result so far: 7908.79797
If we subtract 693 from 790, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 12:
If we divide 970 by 99, we get 9 and a remainder of 79.
Put 9 as the next digit of the answer. 
Result so far: 7908.797979
The remainder is 79 after subtracting 891 from 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 13:
99 can be fit into 790 7 times, resulting in a remainder of 97.
Use 7 as the next digit of our solution. 
Result so far: 7908.7979797
Subtracting 693 from 790 leaves us with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Let's proceed to step 14:
970 divided by 99 is 9 with a remainder of 79.
Put 9 as the next digit of the answer. 
Result so far: 7908.79797979
If we take 891 away from 970, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

In conclusion, the division gives 7908.79797979 with a balance of 7.9e-08.
