We divide 781691 by 12
The aim is to understand the frequency of 12 in 781691.

On to step 1:
12 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 12

Going ahead to step 2:
12 goes into 78 6 times with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 72 away from 78, we end up with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 12

Moving on to step 3:
If we divide 61 by 12, we get 5 and a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 65.0
Deduct 60 from 61 and we're left with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 12

Step 4:
The number 12 fits into 16 1 times, leaving a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 651.0
If we subtract 12 from 16, we get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 12

Advancing to step 5:
12 goes into 49 4 times with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 6514.0
Subtract 48 from 49 to get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 12

Moving on to step 6:
12 goes into 11 0 times with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 65140.0
If we subtract 0 from 11, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
12 can be fit into 110 9 times, resulting in a remainder of 2.
The next digit of our result is 9. 
Result so far: 65140.9
Deduct 108 from 110 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
The number 12 fits into 20 1 times, leaving a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 65140.91
If we take 12 away from 20, 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.

Moving on to step 9:
80 divided by 12 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 65140.916
If we subtract 72 from 80, 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.

Let's proceed to step 10:
If we divide 80 by 12, we get 6 and a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 65140.9166
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.

Our division results in 65140.9166 with a remaining 8e-05.
