286090 divided by 75 
The aim is to understand the frequency of 75 in 286090.

On to step 1:
When dividing 2 by 75, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 75

Advancing to step 2:
When dividing 28 by 75, we get 0 with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 75

On to step 3:
The number 75 fits into 286 3 times, leaving a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 225 away from 286, we end up with 61.
Take the next digit (0) from the dividend and append it to 61, then repeat: 610 / 75

Going ahead to step 4:
When dividing 610 by 75, we get 8 with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
The remainder is 10 after subtracting 600 from 610.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 75

Going ahead to step 5:
109 divided by 75 is 1 with a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 381.0
If we subtract 75 from 109, we get 34.
Grab the next digit (0) from the dividend, add it to 34, then carry on: 340 / 75

Advancing to step 6:
75 goes into 340 4 times with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 3814.0
Deduct 300 from 340 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 7:
When dividing 400 by 75, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 3814.5
If we take 375 away from 400, 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.

On to step 8:
If we divide 250 by 75, we get 3 and a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 3814.53
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.

Let's proceed to step 9:
The number 75 fits into 250 3 times, leaving a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 3814.533
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

In conclusion, the division gives 3814.533 with a balance of 0.0025.
