We're dividing 753850 by 99 
The aim is to understand the frequency of 99 in 753850.

Advancing to step 1:
When dividing 7 by 99, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 99

Moving on to step 2:
75 divided by 99 is 0 with a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Append the next digit (3) from the dividend to 75 and continue with: 753 / 99

Advancing to step 3:
753 divided by 99 is 7 with a remainder of 60.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 693 away from 753, we end up with 60.
Fetch the next digit (8) from the dividend, attach it to 60 and continue: 608 / 99

Going ahead to step 4:
608 divided by 99 is 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
The remainder is 14 after subtracting 594 from 608.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 99

Step 5:
99 goes into 145 1 times with a remainder of 46.
Write down 1 as next digit of the result. 
Result so far: 761.0
Subtract 99 from 145 to get 46.
Include the next digit (0) from the dividend after 46, then repeat: 460 / 99

Step 6:
99 goes into 460 4 times with a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 7614.0
Subtract 396 from 460 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 7:
99 goes into 640 6 times with a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 7614.6
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:
The number 99 fits into 460 4 times, leaving a remainder of 64.
The next digit of our result is 4. 
Result so far: 7614.64
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.

Let's proceed to step 9:
99 can be fit into 640 6 times, resulting in a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 7614.646
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 10:
99 can be fit into 460 4 times, resulting in a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 7614.6464
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.

Let's proceed to step 11:
99 goes into 640 6 times with a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 7614.64646
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.

Going ahead to step 12:
460 divided by 99 is 4 with a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 7614.646464
Subtracting 396 from 460 leaves us 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.

Let's proceed to step 13:
99 can be fit into 640 6 times, resulting in a remainder of 46.
Record the quotient 6 as the next digit in the result. 
Result so far: 7614.6464646
Subtracting 594 from 640 leaves us 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.

On to step 14:
99 can be fit into 460 4 times, resulting in a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 7614.64646464
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.

After the division, we end up with 7614.64646464 and a remainder of 6.4e-08.
