We divide 231438 by 12
The aim is to understand the frequency of 12 in 231438.

Going ahead to step 1:
12 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 12

Let's proceed to step 2:
The number 12 fits into 23 1 times, leaving a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 12 from 23 to get 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 12

Advancing to step 3:
12 goes into 111 9 times with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 19.0
The remainder is 3 after subtracting 108 from 111.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 12

Moving on to step 4:
12 goes into 34 2 times with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 192.0
If we subtract 24 from 34, we get 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 12

Let's proceed to step 5:
If we divide 103 by 12, we get 8 and a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 1928.0
The remainder is 7 after subtracting 96 from 103.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 12

Moving on to step 6:
The number 12 fits into 78 6 times, leaving a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 19286.0
Deduct 72 from 78 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.

Advancing to step 7:
If we divide 60 by 12, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 19286.5
Subtracting 60 from 60 leaves us 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.

Moving on to step 8:
12 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 19286.5
Deduct 0 from 0 and we're left 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.

On to step 9:
12 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 19286.5
Deduct 0 from 0 and we're left 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.

The final result is 19286.5 with a remainder of 0.0.
