Let's divide 620904 by 99
The aim is to understand the frequency of 99 in 620904.

Moving on to step 1:
99 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 99

Let's proceed to step 2:
When dividing 62 by 99, we get 0 with a remainder of 62.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 62, we end up with 62.
Take the next digit (0) from the dividend and append it to 62, then repeat: 620 / 99

Step 3:
The number 99 fits into 620 6 times, leaving a remainder of 26.
The next digit of our result is 6. 
Result so far: 6.0
If we take 594 away from 620, we end up with 26.
Include the next digit (9) from the dividend after 26, then repeat: 269 / 99

On to step 4:
If we divide 269 by 99, we get 2 and a remainder of 71.
Put 2 as the next digit of the answer. 
Result so far: 62.0
The remainder is 71 after subtracting 198 from 269.
Append the next digit (0) from the dividend to 71 and continue with: 710 / 99

Let's proceed to step 5:
710 divided by 99 is 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 627.0
If we subtract 693 from 710, we get 17.
Append the next digit (4) from the dividend to 17 and continue with: 174 / 99

Advancing to step 6:
174 divided by 99 is 1 with a remainder of 75.
Record the quotient 1 as the next digit in the result. 
Result so far: 6271.0
If we subtract 99 from 174, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 7:
When dividing 750 by 99, we get 7 with a remainder of 57.
The next digit of our result is 7. 
Result so far: 6271.7
If we subtract 693 from 750, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 8:
If we divide 570 by 99, we get 5 and a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 6271.75
The remainder is 75 after subtracting 495 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 9:
99 goes into 750 7 times with a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 6271.757
The remainder is 57 after subtracting 693 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 10:
570 divided by 99 is 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 6271.7575
Deduct 495 from 570 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 11:
99 can be fit into 750 7 times, resulting in a remainder of 57.
Put 7 as the next digit of the answer. 
Result so far: 6271.75757
Deduct 693 from 750 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 12:
The number 99 fits into 570 5 times, leaving a remainder of 75.
The next digit of our result is 5. 
Result so far: 6271.757575
Deduct 495 from 570 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 13:
99 can be fit into 750 7 times, resulting in a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 6271.7575757
Subtract 693 from 750 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 14:
570 divided by 99 is 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 6271.75757575
Deduct 495 from 570 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The quotient of the division is 6271.75757575, and the remainder is 7.5e-08.
