We look at the division of 442929 by 99 
The aim is to understand the frequency of 99 in 442929.

Step 1:
If we divide 4 by 99, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 99

Step 2:
99 goes into 44 0 times with a remainder of 44.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 44 leaves us with 44.
Include the next digit (2) from the dividend after 44, then repeat: 442 / 99

Let's proceed to step 3:
99 goes into 442 4 times with a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 396 from 442 to get 46.
Bring next digit (9) of the dividend behind the 46 and repeat the process: 469 / 99

Let's proceed to step 4:
469 divided by 99 is 4 with a remainder of 73.
Write down 4 as next digit of the result. 
Result so far: 44.0
Subtract 396 from 469 to get 73.
Bring next digit (2) of the dividend behind the 73 and repeat the process: 732 / 99

Moving on to step 5:
99 goes into 732 7 times with a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 447.0
If we subtract 693 from 732, we get 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 99

Moving on to step 6:
99 can be fit into 399 4 times, resulting in a remainder of 3.
The next digit of our result is 4. 
Result so far: 4474.0
Subtracting 396 from 399 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
99 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 4474.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
99 can be fit into 300 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 4474.03
Deduct 297 from 300 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
When dividing 30 by 99, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 4474.03
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
The number 99 fits into 300 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 4474.0303
If we take 297 away from 300, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 11:
99 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 4474.0303
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
300 divided by 99 is 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 4474.030303
Deduct 297 from 300 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 13:
30 divided by 99 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 4474.030303
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 14:
If we divide 300 by 99, we get 3 and a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 4474.03030303
Subtracting 297 from 300 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

In conclusion, the division gives 4474.03030303 with a balance of 3e-09.
