340242 divided by 12 
The aim is to understand the frequency of 12 in 340242.

Let's proceed to step 1:
12 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 12

Moving on to step 2:
If we divide 34 by 12, we get 2 and a remainder of 10.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 24 from 34 leaves us with 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 12

Going ahead to step 3:
100 divided by 12 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtracting 96 from 100 leaves us with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 12

On to step 4:
If we divide 42 by 12, we get 3 and a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 283.0
Deduct 36 from 42 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 12

Moving on to step 5:
64 divided by 12 is 5 with a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 2835.0
The remainder is 4 after subtracting 60 from 64.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 12

Advancing to step 6:
The number 12 fits into 42 3 times, leaving a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 28353.0
Deduct 36 from 42 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
12 goes into 60 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 28353.5
If we take 60 away from 60, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
When dividing 0 by 12, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 28353.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 28353.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 28353.5 with a remaining 0.0.
