Let's divide 650310 by 12
The aim is to understand the frequency of 12 in 650310.

Let's proceed to step 1:
6 divided by 12 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 12

On to step 2:
65 divided by 12 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 60 from 65 leaves us with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 12

On to step 3:
The number 12 fits into 50 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 54.0
The remainder is 2 after subtracting 48 from 50.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 12

Step 4:
12 goes into 23 1 times with a remainder of 11.
The next digit of our result is 1. 
Result so far: 541.0
Deduct 12 from 23 and we're left with 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 12

Step 5:
When dividing 111 by 12, we get 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 5419.0
Subtract 108 from 111 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 12

Moving on to step 6:
12 can be fit into 30 2 times, resulting in a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 54192.0
Deduct 24 from 30 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.

Step 7:
60 divided by 12 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 54192.5
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 8:
0 divided by 12 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 54192.5
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.

Moving on to step 9:
0 divided by 12 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 54192.5
The remainder is 0 after subtracting 0 from 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 result is 54192.5 with a remainder of 0.0.
