575814 ÷ 99 
The aim is to understand the frequency of 99 in 575814.

Step 1:
If we divide 5 by 99, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 99

Going ahead to step 2:
The number 99 fits into 57 0 times, leaving a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Grab the next digit (5) from the dividend, add it to 57, then carry on: 575 / 99

Step 3:
575 divided by 99 is 5 with a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 80 after subtracting 495 from 575.
Grab the next digit (8) from the dividend, add it to 80, then carry on: 808 / 99

Moving on to step 4:
If we divide 808 by 99, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 58.0
Deduct 792 from 808 and we're left with 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 99

Step 5:
When dividing 161 by 99, we get 1 with a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 581.0
Deduct 99 from 161 and we're left with 62.
Bring next digit (4) of the dividend behind the 62 and repeat the process: 624 / 99

Advancing to step 6:
624 divided by 99 is 6 with a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 5816.0
If we subtract 594 from 624, 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 7:
When dividing 300 by 99, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 5816.3
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.

Advancing to step 8:
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: 5816.3
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.

Advancing to step 9:
99 can be fit into 300 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 5816.303
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.

Going ahead to step 10:
When dividing 30 by 99, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 5816.303
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.

Step 11:
300 divided by 99 is 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 5816.30303
If we subtract 297 from 300, we get 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 12:
99 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 5816.30303
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.

Advancing to step 13:
The number 99 fits into 300 3 times, leaving a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 5816.3030303
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.

On to step 14:
The number 99 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 5816.3030303
If we take 0 away from 30, we end up 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.

In conclusion, the division gives 5816.3030303 with a balance of 3e-08.
