151179 divided by 12 
The aim is to understand the frequency of 12 in 151179.

Let's proceed to step 1:
12 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 12

On to step 2:
12 goes into 15 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 12 from 15 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 12

Advancing to step 3:
The number 12 fits into 31 2 times, leaving a remainder of 7.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 7 after subtracting 24 from 31.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 12

On to step 4:
When dividing 71 by 12, we get 5 with a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 125.0
If we subtract 60 from 71, we get 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 12

On to step 5:
When dividing 117 by 12, we get 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 1259.0
The remainder is 9 after subtracting 108 from 117.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 12

Let's proceed to step 6:
If we divide 99 by 12, we get 8 and a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 12598.0
If we subtract 96 from 99, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
The number 12 fits into 30 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 12598.2
Subtracting 24 from 30 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
12 can be fit into 60 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 12598.25
If we take 60 away from 60, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
0 divided by 12 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12598.25
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12598.25
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 12598.25 with a remaining 0.0.
