We're dividing 286733 by 12 
The aim is to understand the frequency of 12 in 286733.

Step 1:
The number 12 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 12

Let's proceed to step 2:
The number 12 fits into 28 2 times, leaving a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 24 from 28 to get 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 12

On to step 3:
12 can be fit into 46 3 times, resulting in a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we take 36 away from 46, we end up with 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 12

Let's proceed to step 4:
If we divide 107 by 12, we get 8 and a remainder of 11.
The next digit of our result is 8. 
Result so far: 238.0
Deduct 96 from 107 and we're left with 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 12

Moving on to step 5:
The number 12 fits into 113 9 times, leaving a remainder of 5.
The next digit of our result is 9. 
Result so far: 2389.0
Deduct 108 from 113 and we're left with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 12

Step 6:
53 divided by 12 is 4 with a remainder of 5.
The next digit of our result is 4. 
Result so far: 23894.0
The remainder is 5 after subtracting 48 from 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
50 divided by 12 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 23894.4
Deduct 48 from 50 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
The number 12 fits into 20 1 times, leaving a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 23894.41
If we take 12 away from 20, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 23894.416
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
When dividing 80 by 12, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 23894.4166
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 23894.4166 with a remaining 8e-05.
