We look at the division of 77784469 by 12 
The aim is to understand the frequency of 12 in 77784469.

Step 1:
When dividing 7 by 12, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 12

On to step 2:
The number 12 fits into 77 6 times, leaving a remainder of 5.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 72 from 77, we get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 12

Step 3:
When dividing 57 by 12, we get 4 with a remainder of 9.
The next digit of our result is 4. 
Result so far: 64.0
If we subtract 48 from 57, we get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 12

Let's proceed to step 4:
98 divided by 12 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 648.0
Deduct 96 from 98 and we're left with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 12

Advancing to step 5:
24 divided by 12 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 6482.0
Subtract 24 from 24 to get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 12

Moving on to step 6:
4 divided by 12 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 64820.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 12

Step 7:
When dividing 46 by 12, we get 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 648203.0
If we take 36 away from 46, we end up with 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 12

Let's proceed to step 8:
The number 12 fits into 109 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 6482039.0
The remainder is 1 after subtracting 108 from 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
The number 12 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 6482039.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
12 can be fit into 100 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 6482039.08
If we subtract 96 from 100, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
12 goes into 40 3 times with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 6482039.083
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
When dividing 40 by 12, we get 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 6482039.0833
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 6482039.0833, and the remainder is 4e-05.
