We're dividing 402582 by 75 
The aim is to understand the frequency of 75 in 402582.

Advancing to step 1:
4 divided by 75 is 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:
If we divide 40 by 75, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Bring next digit (2) of the dividend behind the 40 and repeat the process: 402 / 75

On to step 3:
402 divided by 75 is 5 with a remainder of 27.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 375 from 402 leaves us with 27.
Take the next digit (5) from the dividend and append it to 27, then repeat: 275 / 75

Advancing to step 4:
If we divide 275 by 75, we get 3 and a remainder of 50.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
If we subtract 225 from 275, we get 50.
Append the next digit (8) from the dividend to 50 and continue with: 508 / 75

Moving on to step 5:
508 divided by 75 is 6 with a remainder of 58.
Use 6 as the next digit of our solution. 
Result so far: 536.0
Subtracting 450 from 508 leaves us with 58.
Grab the next digit (2) from the dividend, add it to 58, then carry on: 582 / 75

Let's proceed to step 6:
The number 75 fits into 582 7 times, leaving a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 5367.0
Subtract 525 from 582 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 7:
When dividing 570 by 75, we get 7 with a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 5367.7
Subtracting 525 from 570 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 8:
75 goes into 450 6 times with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 5367.76
Deduct 450 from 450 and we're left 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.

Let's proceed to step 9:
When dividing 0 by 75, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5367.76
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.

On to step 10:
0 divided by 75 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5367.76
If we subtract 0 from 0, we 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.

The quotient of the division is 5367.76, and the remainder is 0.0.
