We're dividing 348814 by 12 
The aim is to understand the frequency of 12 in 348814.

Going ahead to step 1:
12 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 12

Step 2:
When dividing 34 by 12, we get 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 24 away from 34, we end up with 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 12

Moving on to step 3:
12 can be fit into 108 9 times, resulting in a remainder of 0.
The next digit of our result is 9. 
Result so far: 29.0
Subtracting 108 from 108 leaves us with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 12

Moving on to step 4:
If we divide 8 by 12, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 290.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 12

Step 5:
The number 12 fits into 81 6 times, leaving a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 2906.0
If we take 72 away from 81, we end up with 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 12

Moving on to step 6:
94 divided by 12 is 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 29067.0
Subtract 84 from 94 to get 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 7:
When dividing 100 by 12, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 29067.8
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 8:
40 divided by 12 is 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 29067.83
If we take 36 away from 40, 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.

Step 9:
The number 12 fits into 40 3 times, leaving a remainder of 4.
The next digit of our result is 3. 
Result so far: 29067.833
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 29067.833 with a remaining 0.0004.
