514171 ÷ 99 
The aim is to understand the frequency of 99 in 514171.

Moving on to step 1:
99 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 99

Step 2:
If we divide 51 by 99, we get 0 and a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Grab the next digit (4) from the dividend, add it to 51, then carry on: 514 / 99

Going ahead to step 3:
When dividing 514 by 99, we get 5 with a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 495 from 514, we get 19.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 99

On to step 4:
99 goes into 191 1 times with a remainder of 92.
Use 1 as the next digit of our solution. 
Result so far: 51.0
Deduct 99 from 191 and we're left with 92.
Fetch the next digit (7) from the dividend, attach it to 92 and continue: 927 / 99

Step 5:
99 can be fit into 927 9 times, resulting in a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 519.0
Subtracting 891 from 927 leaves us with 36.
Append the next digit (1) from the dividend to 36 and continue with: 361 / 99

Moving on to step 6:
When dividing 361 by 99, we get 3 with a remainder of 64.
Put 3 as the next digit of the answer. 
Result so far: 5193.0
The remainder is 64 after subtracting 297 from 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 7:
The number 99 fits into 640 6 times, leaving a remainder of 46.
Record the quotient 6 as the next digit in the result. 
Result so far: 5193.6
If we subtract 594 from 640, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 8:
If we divide 460 by 99, we get 4 and a remainder of 64.
The next digit of our result is 4. 
Result so far: 5193.64
If we take 396 away from 460, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 9:
When dividing 640 by 99, we get 6 with a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 5193.646
Subtract 594 from 640 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 10:
460 divided by 99 is 4 with a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 5193.6464
The remainder is 64 after subtracting 396 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 11:
99 goes into 640 6 times with a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 5193.64646
Deduct 594 from 640 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
When dividing 460 by 99, we get 4 with a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 5193.646464
The remainder is 64 after subtracting 396 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
640 divided by 99 is 6 with a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 5193.6464646
If we take 594 away from 640, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 14:
If we divide 460 by 99, we get 4 and a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 5193.64646464
Deduct 396 from 460 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 5193.64646464 and a remainder of 6.4e-08.
