276289 ÷ 99 
The aim is to understand the frequency of 99 in 276289.

Step 1:
If we divide 2 by 99, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 99

On to step 2:
27 divided by 99 is 0 with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 27 to get 27.
Bring next digit (6) of the dividend behind the 27 and repeat the process: 276 / 99

On to step 3:
When dividing 276 by 99, we get 2 with a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 198 from 276 to get 78.
Bring next digit (2) of the dividend behind the 78 and repeat the process: 782 / 99

Step 4:
782 divided by 99 is 7 with a remainder of 89.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Subtracting 693 from 782 leaves us with 89.
Append the next digit (8) from the dividend to 89 and continue with: 898 / 99

Step 5:
The number 99 fits into 898 9 times, leaving a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 279.0
Subtract 891 from 898 to get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 99

Let's proceed to step 6:
The number 99 fits into 79 0 times, leaving a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 2790.0
If we take 0 away from 79, 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.

Going ahead to step 7:
790 divided by 99 is 7 with a remainder of 97.
Use 7 as the next digit of our solution. 
Result so far: 2790.7
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.

On to step 8:
99 goes into 970 9 times with a remainder of 79.
Use 9 as the next digit of our solution. 
Result so far: 2790.79
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.

Let's proceed to step 9:
790 divided by 99 is 7 with a remainder of 97.
Write down 7 as next digit of the result. 
Result so far: 2790.797
Subtract 693 from 790 to 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.

Let's proceed to step 10:
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: 2790.7979
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 11:
If we divide 790 by 99, we get 7 and a remainder of 97.
Record the quotient 7 as the next digit in the result. 
Result so far: 2790.79797
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.

On to step 12:
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: 2790.797979
Subtract 891 from 970 to 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.

Let's proceed to step 13:
The number 99 fits into 790 7 times, leaving a remainder of 97.
The number 7 becomes the next digit in our result. 
Result so far: 2790.7979797
Deduct 693 from 790 and we're left 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.

Step 14:
The number 99 fits into 970 9 times, leaving a remainder of 79.
The number 9 becomes the next digit in our result. 
Result so far: 2790.79797979
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.

In conclusion, the division gives 2790.79797979 with a balance of 7.9e-08.
