788942 divided by 12 
The aim is to understand the frequency of 12 in 788942.

Moving on to step 1:
If we divide 7 by 12, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 12

On to step 2:
If we divide 78 by 12, we get 6 and a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 72 from 78, we get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 12

Advancing to step 3:
68 divided by 12 is 5 with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 65.0
If we subtract 60 from 68, we get 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 12

Step 4:
89 divided by 12 is 7 with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 657.0
If we subtract 84 from 89, we get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 12

Advancing to step 5:
If we divide 54 by 12, we get 4 and a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 6574.0
Subtract 48 from 54 to get 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 12

On to step 6:
62 divided by 12 is 5 with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 65745.0
If we subtract 60 from 62, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
12 goes into 20 1 times with a remainder of 8.
The next digit of our result is 1. 
Result so far: 65745.1
If we subtract 12 from 20, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
12 goes into 80 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 65745.16
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
When dividing 80 by 12, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 65745.166
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 65745.166 and a remainder of 0.0008.
