437962 ÷ 99 
The aim is to understand the frequency of 99 in 437962.

Step 1:
99 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 99

Moving on to step 2:
When dividing 43 by 99, we get 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Bring next digit (7) of the dividend behind the 43 and repeat the process: 437 / 99

Going ahead to step 3:
437 divided by 99 is 4 with a remainder of 41.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 396 from 437, we get 41.
Bring next digit (9) of the dividend behind the 41 and repeat the process: 419 / 99

On to step 4:
99 goes into 419 4 times with a remainder of 23.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
If we take 396 away from 419, we end up with 23.
Append the next digit (6) from the dividend to 23 and continue with: 236 / 99

Let's proceed to step 5:
99 goes into 236 2 times with a remainder of 38.
The next digit of our result is 2. 
Result so far: 442.0
Subtract 198 from 236 to get 38.
Include the next digit (2) from the dividend after 38, then repeat: 382 / 99

Advancing to step 6:
If we divide 382 by 99, we get 3 and a remainder of 85.
Write down 3 as next digit of the result. 
Result so far: 4423.0
Subtracting 297 from 382 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 7:
When dividing 850 by 99, we get 8 with a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 4423.8
Deduct 792 from 850 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 8:
When dividing 580 by 99, we get 5 with a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 4423.85
If we subtract 495 from 580, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 9:
If we divide 850 by 99, we get 8 and a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 4423.858
Subtracting 792 from 850 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 10:
The number 99 fits into 580 5 times, leaving a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 4423.8585
Subtract 495 from 580 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 11:
850 divided by 99 is 8 with a remainder of 58.
The next digit of our result is 8. 
Result so far: 4423.85858
Subtract 792 from 850 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 12:
The number 99 fits into 580 5 times, leaving a remainder of 85.
The next digit of our result is 5. 
Result so far: 4423.858585
Deduct 495 from 580 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 13:
99 goes into 850 8 times with a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 4423.8585858
If we take 792 away from 850, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 14:
99 can be fit into 580 5 times, resulting in a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 4423.85858585
The remainder is 85 after subtracting 495 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

In conclusion, the division gives 4423.85858585 with a balance of 8.5e-08.
