Let's divide 550166 by 99
The aim is to understand the frequency of 99 in 550166.

Going ahead to step 1:
The number 99 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 99

Advancing to step 2:
The number 99 fits into 55 0 times, leaving a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Grab the next digit (0) from the dividend, add it to 55, then carry on: 550 / 99

Advancing to step 3:
When dividing 550 by 99, we get 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 495 away from 550, we end up with 55.
Take the next digit (1) from the dividend and append it to 55, then repeat: 551 / 99

Step 4:
99 goes into 551 5 times with a remainder of 56.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
Deduct 495 from 551 and we're left with 56.
Include the next digit (6) from the dividend after 56, then repeat: 566 / 99

Let's proceed to step 5:
566 divided by 99 is 5 with a remainder of 71.
The next digit of our result is 5. 
Result so far: 555.0
If we subtract 495 from 566, we get 71.
Include the next digit (6) from the dividend after 71, then repeat: 716 / 99

Step 6:
99 can be fit into 716 7 times, resulting in a remainder of 23.
The next digit of our result is 7. 
Result so far: 5557.0
Subtract 693 from 716 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
99 can be fit into 230 2 times, resulting in a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 5557.2
If we subtract 198 from 230, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 8:
99 goes into 320 3 times with a remainder of 23.
The next digit of our result is 3. 
Result so far: 5557.23
Subtract 297 from 320 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 9:
99 goes into 230 2 times with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 5557.232
The remainder is 32 after subtracting 198 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
If we divide 320 by 99, we get 3 and a remainder of 23.
The next digit of our result is 3. 
Result so far: 5557.2323
If we take 297 away from 320, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 11:
The number 99 fits into 230 2 times, leaving a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 5557.23232
The remainder is 32 after subtracting 198 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
The number 99 fits into 320 3 times, leaving a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 5557.232323
Deduct 297 from 320 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 13:
230 divided by 99 is 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 5557.2323232
Deduct 198 from 230 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 14:
99 can be fit into 320 3 times, resulting in a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 5557.23232323
If we take 297 away from 320, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

After the division, we end up with 5557.23232323 and a remainder of 2.3e-08.
