Let's divide 75009985 by 300
The aim is to understand the frequency of 300 in 75009985.

Going ahead to step 1:
300 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 300

Going ahead to step 2:
300 can be fit into 75 0 times, resulting in a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Take the next digit (0) from the dividend and append it to 75, then repeat: 750 / 300

Going ahead to step 3:
300 goes into 750 2 times with a remainder of 150.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 150 after subtracting 600 from 750.
Bring next digit (0) of the dividend behind the 150 and repeat the process: 1500 / 300

On to step 4:
300 goes into 1500 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Deduct 1500 from 1500 and we're left with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 300

Going ahead to step 5:
300 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 250.0
If we subtract 0 from 9, we get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 300

Let's proceed to step 6:
300 goes into 99 0 times with a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 2500.0
Subtracting 0 from 99 leaves us with 99.
Grab the next digit (8) from the dividend, add it to 99, then carry on: 998 / 300

Step 7:
300 can be fit into 998 3 times, resulting in a remainder of 98.
Put 3 as the next digit of the answer. 
Result so far: 25003.0
The remainder is 98 after subtracting 900 from 998.
Bring next digit (5) of the dividend behind the 98 and repeat the process: 985 / 300

Going ahead to step 8:
300 goes into 985 3 times with a remainder of 85.
Use 3 as the next digit of our solution. 
Result so far: 250033.0
If we take 900 away from 985, we end up 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.

Moving on to step 9:
300 goes into 850 2 times with a remainder of 250.
Record the quotient 2 as the next digit in the result. 
Result so far: 250033.2
Subtracting 600 from 850 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 10:
The number 300 fits into 2500 8 times, leaving a remainder of 100.
Use 8 as the next digit of our solution. 
Result so far: 250033.28
If we take 2400 away from 2500, we end up 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.

Let's proceed to step 11:
1000 divided by 300 is 3 with a remainder of 100.
The number 3 becomes the next digit in our result. 
Result so far: 250033.283
The remainder is 100 after subtracting 900 from 1000.
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.
Put 3 as the next digit of the answer. 
Result so far: 250033.2833
The remainder is 100 after subtracting 900 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The quotient of the division is 250033.2833, and the remainder is 0.001.
