788508 divided by 12 
The aim is to understand the frequency of 12 in 788508.

Step 1:
12 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 12

On to step 2:
78 divided by 12 is 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 6 after subtracting 72 from 78.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 12

Let's proceed to step 3:
If we divide 68 by 12, we get 5 and a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 65.0
If we subtract 60 from 68, we get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 12

On to step 4:
12 goes into 85 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 657.0
If we subtract 84 from 85, we get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 12

On to step 5:
If we divide 10 by 12, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 6570.0
Subtract 0 from 10 to get 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 12

Step 6:
108 divided by 12 is 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 65709.0
If we subtract 108 from 108, 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.

On to step 7:
0 divided by 12 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 65709.0
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.

Advancing to step 8:
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: 65709.0
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.

After the division, we end up with 65709.0 and a remainder of 0.0.
