638322 ÷ 12 
The aim is to understand the frequency of 12 in 638322.

Advancing to step 1:
6 divided by 12 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 12

Advancing to step 2:
12 goes into 63 5 times with a remainder of 3.
The next digit of our result is 5. 
Result so far: 5.0
If we take 60 away from 63, we end up with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 12

On to step 3:
When dividing 38 by 12, we get 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 53.0
The remainder is 2 after subtracting 36 from 38.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 12

Advancing to step 4:
When dividing 23 by 12, we get 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 531.0
The remainder is 11 after subtracting 12 from 23.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 12

Let's proceed to step 5:
12 goes into 112 9 times with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 5319.0
If we take 108 away from 112, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 12

Step 6:
12 can be fit into 42 3 times, resulting in a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 53193.0
Deduct 36 from 42 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 7:
12 can be fit into 60 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 53193.5
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
If we divide 0 by 12, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 53193.5
If we take 0 away from 0, we end up 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 9:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 53193.5
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 quotient of the division is 53193.5, and the remainder is 0.0.
