Let's divide 99120419 by 305
The aim is to understand the frequency of 305 in 99120419.

Advancing to step 1:
9 divided by 305 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 305

Let's proceed to step 2:
The number 305 fits into 99 0 times, leaving a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Include the next digit (1) from the dividend after 99, then repeat: 991 / 305

Going ahead to step 3:
The number 305 fits into 991 3 times, leaving a remainder of 76.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 915 away from 991, we end up with 76.
Grab the next digit (2) from the dividend, add it to 76, then carry on: 762 / 305

Step 4:
The number 305 fits into 762 2 times, leaving a remainder of 152.
Write down 2 as next digit of the result. 
Result so far: 32.0
The remainder is 152 after subtracting 610 from 762.
Fetch the next digit (0) from the dividend, attach it to 152 and continue: 1520 / 305

Let's proceed to step 5:
When dividing 1520 by 305, we get 4 with a remainder of 300.
Write down 4 as next digit of the result. 
Result so far: 324.0
If we take 1220 away from 1520, we end up with 300.
Take the next digit (4) from the dividend and append it to 300, then repeat: 3004 / 305

Moving on to step 6:
If we divide 3004 by 305, we get 9 and a remainder of 259.
Write down 9 as next digit of the result. 
Result so far: 3249.0
If we subtract 2745 from 3004, we get 259.
Append the next digit (1) from the dividend to 259 and continue with: 2591 / 305

Moving on to step 7:
The number 305 fits into 2591 8 times, leaving a remainder of 151.
The next digit of our result is 8. 
Result so far: 32498.0
If we take 2440 away from 2591, we end up with 151.
Take the next digit (9) from the dividend and append it to 151, then repeat: 1519 / 305

Step 8:
When dividing 1519 by 305, we get 4 with a remainder of 299.
The next digit of our result is 4. 
Result so far: 324984.0
If we take 1220 away from 1519, we end up with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Let's proceed to step 9:
305 goes into 2990 9 times with a remainder of 245.
The next digit of our result is 9. 
Result so far: 324984.9
If we subtract 2745 from 2990, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Moving on to step 10:
305 can be fit into 2450 8 times, resulting in a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 324984.98
Deduct 2440 from 2450 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
If we divide 100 by 305, we get 0 and a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 324984.98
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 12:
The number 305 fits into 1000 3 times, leaving a remainder of 85.
The next digit of our result is 3. 
Result so far: 324984.9803
Deduct 915 from 1000 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 13:
When dividing 850 by 305, we get 2 with a remainder of 240.
Write down 2 as next digit of the result. 
Result so far: 324984.98032
If we subtract 610 from 850, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 14:
The number 305 fits into 2400 7 times, leaving a remainder of 265.
Record the quotient 7 as the next digit in the result. 
Result so far: 324984.980327
Subtract 2135 from 2400 to get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Step 15:
The number 305 fits into 2650 8 times, leaving a remainder of 210.
The next digit of our result is 8. 
Result so far: 324984.9803278
Deduct 2440 from 2650 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 16:
The number 305 fits into 2100 6 times, leaving a remainder of 270.
The number 6 becomes the next digit in our result. 
Result so far: 324984.98032786
If we subtract 1830 from 2100, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

The final outcome is 324984.98032786, with a leftover of 2.7e-07.
