565821 ÷ 12 
The aim is to understand the frequency of 12 in 565821.

On to step 1:
12 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 12

Going ahead to step 2:
If we divide 56 by 12, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 48 from 56 leaves us with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 12

Step 3:
When dividing 85 by 12, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 47.0
Subtract 84 from 85 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 12

On to step 4:
18 divided by 12 is 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 471.0
Subtracting 12 from 18 leaves us with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 12

On to step 5:
When dividing 62 by 12, we get 5 with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 4715.0
If we subtract 60 from 62, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 12

Let's proceed to step 6:
12 can be fit into 21 1 times, resulting in a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 47151.0
If we subtract 12 from 21, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
The number 12 fits into 90 7 times, leaving a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 47151.7
Deduct 84 from 90 and we're left 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.

Advancing to step 8:
60 divided by 12 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 47151.75
If we subtract 60 from 60, 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.

Step 9:
When dividing 0 by 12, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 47151.75
Deduct 0 from 0 and we're left 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.

Advancing to step 10:
When dividing 0 by 12, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 47151.75
Deduct 0 from 0 and we're left 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 47151.75 with a remaining 0.0.
