Let's divide 620712 by 12
The aim is to understand the frequency of 12 in 620712.

Let's proceed to step 1:
The number 12 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 12

On to step 2:
62 divided by 12 is 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 60 from 62 and we're left with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 12

Step 3:
When dividing 20 by 12, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 51.0
If we subtract 12 from 20, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 12

Advancing to step 4:
12 goes into 87 7 times with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 517.0
Deduct 84 from 87 and we're left with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 12

Moving on to step 5:
When dividing 31 by 12, we get 2 with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 5172.0
Deduct 24 from 31 and we're left with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 12

Advancing to step 6:
12 can be fit into 72 6 times, resulting in a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 51726.0
The remainder is 0 after subtracting 72 from 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 51726.0
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.

Let's proceed to step 8:
12 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 51726.0
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.

Our division results in 51726.0 with a remaining 0.0.
