191873 divided by 12 
The aim is to understand the frequency of 12 in 191873.

Let's proceed to step 1:
1 divided by 12 is 0 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.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 12

Going ahead to step 2:
12 can be fit into 19 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 7 after subtracting 12 from 19.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 12

Going ahead to step 3:
The number 12 fits into 71 5 times, leaving a remainder of 11.
The next digit of our result is 5. 
Result so far: 15.0
Deduct 60 from 71 and we're left with 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 12

Let's proceed to step 4:
The number 12 fits into 118 9 times, leaving a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 159.0
Subtract 108 from 118 to get 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 12

Advancing to step 5:
12 can be fit into 107 8 times, resulting in a remainder of 11.
The next digit of our result is 8. 
Result so far: 1598.0
Subtracting 96 from 107 leaves us with 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 12

Going ahead to step 6:
12 can be fit into 113 9 times, resulting in a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 15989.0
The remainder is 5 after subtracting 108 from 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
12 goes into 50 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 15989.4
Deduct 48 from 50 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
When dividing 20 by 12, we get 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 15989.41
If we take 12 away from 20, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
When dividing 80 by 12, we get 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 15989.416
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
12 can be fit into 80 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 15989.4166
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 15989.4166, and the remainder is 8e-05.
