854191 divided by 12 
The aim is to understand the frequency of 12 in 854191.

Step 1:
8 divided by 12 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 12

Step 2:
If we divide 85 by 12, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 84 from 85 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 12

On to step 3:
When dividing 14 by 12, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 71.0
If we take 12 away from 14, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 12

Moving on to step 4:
When dividing 21 by 12, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 711.0
If we take 12 away from 21, we end up with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 12

Going ahead to step 5:
12 goes into 99 8 times with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 7118.0
Deduct 96 from 99 and we're left with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 12

Step 6:
12 goes into 31 2 times with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 71182.0
Deduct 24 from 31 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.

On to step 7:
The number 12 fits into 70 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 71182.5
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.

Advancing to step 8:
The number 12 fits into 100 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 71182.58
Deduct 96 from 100 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.

On to step 9:
12 can be fit into 40 3 times, resulting in a remainder of 4.
The next digit of our result is 3. 
Result so far: 71182.583
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.

Let's proceed to step 10:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 71182.5833
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.

In conclusion, the division gives 71182.5833 with a balance of 4e-05.
