We're dividing 160924 by 12 
The aim is to understand the frequency of 12 in 160924.

On to step 1:
12 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 12

Advancing to step 2:
12 goes into 16 1 times with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 12 from 16 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 12

On to step 3:
40 divided by 12 is 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 36 from 40 leaves us with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 12

On to step 4:
12 can be fit into 49 4 times, resulting in a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 134.0
If we subtract 48 from 49, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 12

Step 5:
When dividing 12 by 12, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1341.0
Subtracting 12 from 12 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 12

Step 6:
If we divide 4 by 12, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 13410.0
Deduct 0 from 4 and we're left 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 7:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 13410.3
Subtract 36 from 40 to 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.

Advancing to step 8:
40 divided by 12 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 13410.33
If we subtract 36 from 40, 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.

After the division, we end up with 13410.33 and a remainder of 0.004.
