791534 divided by 12 
The aim is to understand the frequency of 12 in 791534.

Let's proceed to step 1:
12 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 12

Advancing to step 2:
The number 12 fits into 79 6 times, leaving a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 72 from 79, we get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 12

Advancing to step 3:
71 divided by 12 is 5 with a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 65.0
Deduct 60 from 71 and we're left with 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 12

Step 4:
If we divide 115 by 12, we get 9 and a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 659.0
Deduct 108 from 115 and we're left with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 12

Going ahead to step 5:
73 divided by 12 is 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 6596.0
If we take 72 away from 73, we end up with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 12

On to step 6:
12 goes into 14 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 65961.0
If we subtract 12 from 14, 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.

On to step 7:
12 can be fit into 20 1 times, resulting in a remainder of 8.
The next digit of our result is 1. 
Result so far: 65961.1
Subtracting 12 from 20 leaves us 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.

Step 8:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 65961.16
If we take 72 away from 80, we end up 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.

Let's proceed to step 9:
12 can be fit into 80 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 65961.166
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 65961.166, with a leftover of 0.0008.
