Let's divide 321651 by 12
The aim is to understand the frequency of 12 in 321651.

Moving on to step 1:
3 divided by 12 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 12

Advancing to step 2:
If we divide 32 by 12, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 24 from 32 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 12

Let's proceed to step 3:
When dividing 81 by 12, we get 6 with a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 26.0
If we take 72 away from 81, we end up with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 12

On to step 4:
If we divide 96 by 12, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 268.0
Subtract 96 from 96 to get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 12

Step 5:
12 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 2680.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 12

Step 6:
When dividing 51 by 12, we get 4 with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 26804.0
If we take 48 away from 51, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
The number 12 fits into 30 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 26804.2
Subtract 24 from 30 to 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.

Advancing to step 8:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 26804.25
Subtract 60 from 60 to 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.

Advancing to step 9:
If we divide 0 by 12, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 26804.25
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.

On to step 10:
If we divide 0 by 12, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 26804.25
Subtract 0 from 0 to 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.

Our division results in 26804.25 with a remaining 0.0.
