We look at the division of 183547 by 12 
The aim is to understand the frequency of 12 in 183547.

Let's proceed to step 1:
1 divided by 12 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 12

On to step 2:
The number 12 fits into 18 1 times, leaving a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 12 from 18 to get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 12

Step 3:
12 goes into 63 5 times with a remainder of 3.
The next digit of our result is 5. 
Result so far: 15.0
If we take 60 away from 63, we end up with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 12

Going ahead to step 4:
12 can be fit into 35 2 times, resulting in a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 152.0
Subtracting 24 from 35 leaves us with 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 12

Let's proceed to step 5:
The number 12 fits into 114 9 times, leaving a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 1529.0
Deduct 108 from 114 and we're left with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 12

On to step 6:
The number 12 fits into 67 5 times, leaving a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 15295.0
Subtract 60 from 67 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
The number 12 fits into 70 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 15295.5
Subtract 60 from 70 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.

Moving on to step 8:
100 divided by 12 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 15295.58
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.

On to step 9:
When dividing 40 by 12, we get 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 15295.583
Deduct 36 from 40 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.

Moving on to step 10:
12 can be fit into 40 3 times, resulting in a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 15295.5833
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.

The final outcome is 15295.5833, with a leftover of 4e-05.
