402519 ÷ 75 
The aim is to understand the frequency of 75 in 402519.

Step 1:
If we divide 4 by 75, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 75

Step 2:
75 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Grab the next digit (2) from the dividend, add it to 40, then carry on: 402 / 75

Advancing to step 3:
The number 75 fits into 402 5 times, leaving a remainder of 27.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 27 after subtracting 375 from 402.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 75

On to step 4:
75 can be fit into 275 3 times, resulting in a remainder of 50.
The next digit of our result is 3. 
Result so far: 53.0
If we take 225 away from 275, we end up with 50.
Include the next digit (1) from the dividend after 50, then repeat: 501 / 75

Step 5:
The number 75 fits into 501 6 times, leaving a remainder of 51.
The number 6 becomes the next digit in our result. 
Result so far: 536.0
If we take 450 away from 501, we end up with 51.
Grab the next digit (9) from the dividend, add it to 51, then carry on: 519 / 75

Let's proceed to step 6:
When dividing 519 by 75, we get 6 with a remainder of 69.
Put 6 as the next digit of the answer. 
Result so far: 5366.0
The remainder is 69 after subtracting 450 from 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 7:
If we divide 690 by 75, we get 9 and a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 5366.9
The remainder is 15 after subtracting 675 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
75 can be fit into 150 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 5366.92
Subtracting 150 from 150 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
If we divide 0 by 75, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 5366.92
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
When dividing 0 by 75, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5366.92
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 5366.92 with a remaining 0.0.
