402876 divided by 99 
The aim is to understand the frequency of 99 in 402876.

Step 1:
When dividing 4 by 99, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 99

Let's proceed to step 2:
40 divided by 99 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Take the next digit (2) from the dividend and append it to 40, then repeat: 402 / 99

Let's proceed to step 3:
402 divided by 99 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 6 after subtracting 396 from 402.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 99

On to step 4:
If we divide 68 by 99, we get 0 and a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtract 0 from 68 to get 68.
Bring next digit (7) of the dividend behind the 68 and repeat the process: 687 / 99

Step 5:
687 divided by 99 is 6 with a remainder of 93.
Use 6 as the next digit of our solution. 
Result so far: 406.0
Subtract 594 from 687 to get 93.
Append the next digit (6) from the dividend to 93 and continue with: 936 / 99

Let's proceed to step 6:
The number 99 fits into 936 9 times, leaving a remainder of 45.
Record the quotient 9 as the next digit in the result. 
Result so far: 4069.0
Subtracting 891 from 936 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 7:
When dividing 450 by 99, we get 4 with a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 4069.4
Subtract 396 from 450 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 8:
If we divide 540 by 99, we get 5 and a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 4069.45
If we take 495 away from 540, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 9:
The number 99 fits into 450 4 times, leaving a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 4069.454
If we subtract 396 from 450, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 10:
540 divided by 99 is 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 4069.4545
Subtract 495 from 540 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 11:
450 divided by 99 is 4 with a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 4069.45454
Deduct 396 from 450 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 12:
If we divide 540 by 99, we get 5 and a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 4069.454545
Subtract 495 from 540 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 13:
If we divide 450 by 99, we get 4 and a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 4069.4545454
Subtracting 396 from 450 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 14:
If we divide 540 by 99, we get 5 and a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 4069.45454545
Subtracting 495 from 540 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

In conclusion, the division gives 4069.45454545 with a balance of 4.5e-08.
