We divide 41939 by 12
The aim is to understand the frequency of 12 in 41939.

Going ahead to step 1:
When dividing 4 by 12, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 12

Let's proceed to step 2:
12 goes into 41 3 times with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 36 away from 41, we end up with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 12

Going ahead to step 3:
When dividing 59 by 12, we get 4 with a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
If we subtract 48 from 59, we get 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 12

On to step 4:
The number 12 fits into 113 9 times, leaving a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 349.0
Subtracting 108 from 113 leaves us with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 12

Step 5:
When dividing 59 by 12, we get 4 with a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 3494.0
Subtract 48 from 59 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 6:
The number 12 fits into 110 9 times, leaving a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 3494.9
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.

Let's proceed to step 7:
12 goes into 20 1 times with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 3494.91
Subtract 12 from 20 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 8:
If we divide 80 by 12, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 3494.916
Deduct 72 from 80 and we're left 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.

Step 9:
80 divided by 12 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 3494.9166
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 3494.9166 with a remainder of 8e-05.
