We're dividing 195139 by 12 
The aim is to understand the frequency of 12 in 195139.

On to step 1:
12 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 12

Going ahead to step 2:
When dividing 19 by 12, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 12 from 19 to get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 12

Moving on to step 3:
When dividing 75 by 12, we get 6 with a remainder of 3.
The next digit of our result is 6. 
Result so far: 16.0
Subtract 72 from 75 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 12

Let's proceed to step 4:
12 can be fit into 31 2 times, resulting in a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 162.0
If we take 24 away from 31, we end up with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 12

Let's proceed to step 5:
73 divided by 12 is 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 1626.0
If we subtract 72 from 73, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 12

Step 6:
12 can be fit into 19 1 times, resulting in a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 16261.0
Deduct 12 from 19 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
12 goes into 70 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 16261.5
If we subtract 60 from 70, 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.

Step 8:
12 can be fit into 100 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 16261.58
The remainder is 4 after subtracting 96 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
12 goes into 40 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 16261.583
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.

Let's proceed to step 10:
12 goes into 40 3 times with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 16261.5833
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 quotient of the division is 16261.5833, and the remainder is 4e-05.
