Let's divide 300503 by 75
The aim is to understand the frequency of 75 in 300503.

Step 1:
If we divide 3 by 75, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 75

On to step 2:
30 divided by 75 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 75

Advancing to step 3:
300 divided by 75 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 0 after subtracting 300 from 300.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 75

Moving on to step 4:
75 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 75

Let's proceed to step 5:
When dividing 50 by 75, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 400.0
If we subtract 0 from 50, we get 50.
Take the next digit (3) from the dividend and append it to 50, then repeat: 503 / 75

On to step 6:
75 goes into 503 6 times with a remainder of 53.
Use 6 as the next digit of our solution. 
Result so far: 4006.0
Deduct 450 from 503 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 7:
If we divide 530 by 75, we get 7 and a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 4006.7
The remainder is 5 after subtracting 525 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
The number 75 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 4006.7
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
The number 75 fits into 500 6 times, leaving a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 4006.706
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
500 divided by 75 is 6 with a remainder of 50.
The next digit of our result is 6. 
Result so far: 4006.7066
If we take 450 away from 500, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 4006.7066, and the remainder is 0.0005.
