We look at the division of 17998996 by 300 
The aim is to understand the frequency of 300 in 17998996.

Step 1:
The number 300 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 300

On to step 2:
When dividing 17 by 300, we get 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 300

Step 3:
300 can be fit into 179 0 times, resulting in a remainder of 179.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 179 after subtracting 0 from 179.
Include the next digit (9) from the dividend after 179, then repeat: 1799 / 300

Going ahead to step 4:
1799 divided by 300 is 5 with a remainder of 299.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 1500 from 1799 to get 299.
Bring next digit (8) of the dividend behind the 299 and repeat the process: 2998 / 300

On to step 5:
When dividing 2998 by 300, we get 9 with a remainder of 298.
Put 9 as the next digit of the answer. 
Result so far: 59.0
The remainder is 298 after subtracting 2700 from 2998.
Bring next digit (9) of the dividend behind the 298 and repeat the process: 2989 / 300

Advancing to step 6:
300 goes into 2989 9 times with a remainder of 289.
Put 9 as the next digit of the answer. 
Result so far: 599.0
If we take 2700 away from 2989, we end up with 289.
Grab the next digit (9) from the dividend, add it to 289, then carry on: 2899 / 300

Going ahead to step 7:
When dividing 2899 by 300, we get 9 with a remainder of 199.
The next digit of our result is 9. 
Result so far: 5999.0
If we subtract 2700 from 2899, we get 199.
Append the next digit (6) from the dividend to 199 and continue with: 1996 / 300

Step 8:
300 can be fit into 1996 6 times, resulting in a remainder of 196.
The next digit of our result is 6. 
Result so far: 59996.0
Subtract 1800 from 1996 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 9:
If we divide 1960 by 300, we get 6 and a remainder of 160.
Put 6 as the next digit of the answer. 
Result so far: 59996.6
Subtract 1800 from 1960 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 10:
300 goes into 1600 5 times with a remainder of 100.
The next digit of our result is 5. 
Result so far: 59996.65
Deduct 1500 from 1600 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 11:
If we divide 1000 by 300, we get 3 and a remainder of 100.
The number 3 becomes the next digit in our result. 
Result so far: 59996.653
Subtracting 900 from 1000 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 12:
300 goes into 1000 3 times with a remainder of 100.
Write down 3 as next digit of the result. 
Result so far: 59996.6533
If we subtract 900 from 1000, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 59996.6533 and a remainder of 0.001.
