We're dividing 680359 by 12 
The aim is to understand the frequency of 12 in 680359.

Going ahead to step 1:
6 divided by 12 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 12

On to step 2:
If we divide 68 by 12, we get 5 and a remainder of 8.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 60 from 68 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 12

On to step 3:
12 goes into 80 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
Subtract 72 from 80 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 12

Going ahead to step 4:
If we divide 83 by 12, we get 6 and a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 566.0
If we take 72 away from 83, we end up with 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 12

Advancing to step 5:
12 goes into 115 9 times with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 5669.0
If we subtract 108 from 115, we get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 12

Advancing to step 6:
79 divided by 12 is 6 with a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 56696.0
Deduct 72 from 79 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
If we divide 70 by 12, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 56696.5
Deduct 60 from 70 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.

On to step 8:
12 goes into 100 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 56696.58
Subtracting 96 from 100 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
12 goes into 40 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 56696.583
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.

Moving on to step 10:
If we divide 40 by 12, we get 3 and a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 56696.5833
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.

After the division, we end up with 56696.5833 and a remainder of 4e-05.
