Let's divide 286866 by 75
The aim is to understand the frequency of 75 in 286866.

Going ahead to step 1:
2 divided by 75 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 75

Moving on to step 2:
The number 75 fits into 28 0 times, leaving a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Grab the next digit (6) from the dividend, add it to 28, then carry on: 286 / 75

On to step 3:
75 goes into 286 3 times with a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 225 from 286 to get 61.
Fetch the next digit (8) from the dividend, attach it to 61 and continue: 618 / 75

Moving on to step 4:
75 can be fit into 618 8 times, resulting in a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 38.0
If we subtract 600 from 618, we get 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 75

Advancing to step 5:
When dividing 186 by 75, we get 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 382.0
If we take 150 away from 186, we end up with 36.
Take the next digit (6) from the dividend and append it to 36, then repeat: 366 / 75

Going ahead to step 6:
If we divide 366 by 75, we get 4 and a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 3824.0
If we subtract 300 from 366, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 7:
660 divided by 75 is 8 with a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 3824.8
The remainder is 60 after subtracting 600 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 8:
When dividing 600 by 75, we get 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 3824.88
The remainder is 0 after subtracting 600 from 600.
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 3824.88, and the remainder is 0.0.
