Let's divide 604274 by 99
The aim is to understand the frequency of 99 in 604274.

On to step 1:
99 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 99

Moving on to step 2:
60 divided by 99 is 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 60, we end up with 60.
Bring next digit (4) of the dividend behind the 60 and repeat the process: 604 / 99

Moving on to step 3:
99 can be fit into 604 6 times, resulting in a remainder of 10.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 594 from 604, we get 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 99

Step 4:
The number 99 fits into 102 1 times, leaving a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 61.0
Subtracting 99 from 102 leaves us with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 99

Moving on to step 5:
99 can be fit into 37 0 times, resulting in a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 610.0
Deduct 0 from 37 and we're left with 37.
Fetch the next digit (4) from the dividend, attach it to 37 and continue: 374 / 99

Going ahead to step 6:
If we divide 374 by 99, we get 3 and a remainder of 77.
Write down 3 as next digit of the result. 
Result so far: 6103.0
If we take 297 away from 374, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 7:
If we divide 770 by 99, we get 7 and a remainder of 77.
Record the quotient 7 as the next digit in the result. 
Result so far: 6103.7
Subtract 693 from 770 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 8:
The number 99 fits into 770 7 times, leaving a remainder of 77.
The next digit of our result is 7. 
Result so far: 6103.77
Subtract 693 from 770 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

After the division, we end up with 6103.77 and a remainder of 0.077.
