We divide 40300 by 75
The aim is to understand the frequency of 75 in 40300.

Let's proceed to step 1:
When dividing 4 by 75, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 75

Going ahead to step 2:
75 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Fetch the next digit (3) from the dividend, attach it to 40 and continue: 403 / 75

Step 3:
When dividing 403 by 75, we get 5 with a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 375 away from 403, we end up with 28.
Grab the next digit (0) from the dividend, add it to 28, then carry on: 280 / 75

On to step 4:
The number 75 fits into 280 3 times, leaving a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
If we take 225 away from 280, we end up with 55.
Grab the next digit (0) from the dividend, add it to 55, then carry on: 550 / 75

On to step 5:
If we divide 550 by 75, we get 7 and a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 537.0
Deduct 525 from 550 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 6:
When dividing 250 by 75, we get 3 with a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 537.3
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 7:
250 divided by 75 is 3 with a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 537.33
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 537.33, with a leftover of 0.025.
