854442 divided by 12 
The aim is to understand the frequency of 12 in 854442.

Moving on to step 1:
12 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 12

Moving on to step 2:
12 can be fit into 85 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 84 away from 85, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 12

Moving on to step 3:
12 goes into 14 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 71.0
If we subtract 12 from 14, we get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 12

Let's proceed to step 4:
12 can be fit into 24 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 712.0
The remainder is 0 after subtracting 24 from 24.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 12

Let's proceed to step 5:
When dividing 4 by 12, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 7120.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 12

Advancing to step 6:
The number 12 fits into 42 3 times, leaving a remainder of 6.
The next digit of our result is 3. 
Result so far: 71203.0
If we subtract 36 from 42, we get 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 7:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 71203.5
Subtracting 60 from 60 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.

On to step 8:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 71203.5
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 9:
12 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 71203.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 71203.5, with a leftover of 0.0.
