We divide 379798 by 12
The aim is to understand the frequency of 12 in 379798.

Moving on 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
Deduct 0 from 3 and we're left with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 12

Let's proceed to step 2:
12 can be fit into 37 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 36 from 37 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 12

On to step 3:
When dividing 19 by 12, we get 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Subtract 12 from 19 to get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 12

On to step 4:
12 can be fit into 77 6 times, resulting in a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 316.0
Deduct 72 from 77 and we're left with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 12

Going ahead to step 5:
12 goes into 59 4 times with a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 3164.0
If we subtract 48 from 59, we get 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 12

Moving on to step 6:
12 goes into 118 9 times with a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 31649.0
If we subtract 108 from 118, we 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.

Moving on to step 7:
If we divide 100 by 12, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 31649.8
If we subtract 96 from 100, 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 8:
12 goes into 40 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 31649.83
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 31649.833
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.

The final outcome is 31649.833, with a leftover of 0.0004.
