286606 ÷ 75 
The aim is to understand the frequency of 75 in 286606.

Moving on to step 1:
If we divide 2 by 75, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 75

Moving on to step 2:
The number 75 fits into 28 0 times, leaving a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Grab the next digit (6) from the dividend, add it to 28, then carry on: 286 / 75

Advancing to step 3:
The number 75 fits into 286 3 times, leaving a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 225 from 286 and we're left with 61.
Fetch the next digit (6) from the dividend, attach it to 61 and continue: 616 / 75

Going ahead to step 4:
616 divided by 75 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 38.0
Deduct 600 from 616 and we're left with 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 75

Advancing to step 5:
The number 75 fits into 160 2 times, leaving a remainder of 10.
The next digit of our result is 2. 
Result so far: 382.0
Deduct 150 from 160 and we're left with 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 75

Step 6:
106 divided by 75 is 1 with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 3821.0
The remainder is 31 after subtracting 75 from 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 7:
The number 75 fits into 310 4 times, leaving a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 3821.4
Deduct 300 from 310 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
If we divide 100 by 75, we get 1 and a remainder of 25.
The next digit of our result is 1. 
Result so far: 3821.41
Deduct 75 from 100 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 9:
250 divided by 75 is 3 with a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 3821.413
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.

Going ahead to step 10:
The number 75 fits into 250 3 times, leaving a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 3821.4133
Subtracting 225 from 250 leaves us 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.

After the division, we end up with 3821.4133 and a remainder of 0.00025.
