We divide 455255 by 12
The aim is to understand the frequency of 12 in 455255.

Step 1:
If we divide 4 by 12, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our 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:
The number 12 fits into 45 3 times, leaving a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 36 from 45 and we're left with 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 12

On to step 3:
When dividing 95 by 12, we get 7 with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
If we subtract 84 from 95, we get 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 12

Advancing to step 4:
12 can be fit into 112 9 times, resulting in a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 379.0
Deduct 108 from 112 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 12

Moving on to step 5:
12 goes into 45 3 times with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 3793.0
Subtract 36 from 45 to get 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 12

Advancing to step 6:
95 divided by 12 is 7 with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 37937.0
The remainder is 11 after subtracting 84 from 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
12 goes into 110 9 times with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 37937.9
Subtracting 108 from 110 leaves us 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.

Step 8:
20 divided by 12 is 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 37937.91
Subtracting 12 from 20 leaves us 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.

Going ahead to step 9:
12 goes into 80 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 37937.916
Subtract 72 from 80 to get 8.
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:
12 goes into 80 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 37937.9166
If we subtract 72 from 80, we get 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 37937.9166 with a remaining 8e-05.
