459257 divided by 12 
The aim is to understand the frequency of 12 in 459257.

Advancing to step 1:
The number 12 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 12

Advancing to step 2:
When dividing 45 by 12, we get 3 with a remainder of 9.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 9 after subtracting 36 from 45.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 12

Going ahead to step 3:
12 goes into 99 8 times with a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 38.0
Subtract 96 from 99 to get 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 12

Step 4:
When dividing 32 by 12, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 382.0
The remainder is 8 after subtracting 24 from 32.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 12

Let's proceed to step 5:
The number 12 fits into 85 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 3827.0
If we subtract 84 from 85, we get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 12

Advancing to step 6:
When dividing 17 by 12, we get 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 38271.0
Subtract 12 from 17 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
12 can be fit into 50 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 38271.4
The remainder is 2 after subtracting 48 from 50.
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:
12 goes into 20 1 times with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 38271.41
Deduct 12 from 20 and we're left 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.

Moving on to step 9:
If we divide 80 by 12, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 38271.416
Deduct 72 from 80 and we're left 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.

Moving on to step 10:
If we divide 80 by 12, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 38271.4166
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.

The final result is 38271.4166 with a remainder of 8e-05.
