We divide 342481 by 12
The aim is to understand the frequency of 12 in 342481.

On to step 1:
If we divide 3 by 12, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 12

Going ahead to step 2:
34 divided by 12 is 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 10 after subtracting 24 from 34.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 12

Step 3:
When dividing 102 by 12, we get 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtract 96 from 102 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 12

Step 4:
12 can be fit into 64 5 times, resulting in a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 285.0
The remainder is 4 after subtracting 60 from 64.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 12

Step 5:
If we divide 48 by 12, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 2854.0
If we take 48 away from 48, we end up with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 12

On to step 6:
If we divide 1 by 12, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 28540.0
Subtract 0 from 1 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
12 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 28540.0
Subtracting 0 from 10 leaves us 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.

Step 8:
If we divide 100 by 12, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 28540.08
If we take 96 away from 100, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 28540.083
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 28540.0833
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 28540.0833 with a remaining 4e-05.
