276070 ÷ 12 
The aim is to understand the frequency of 12 in 276070.

Let's proceed to step 1:
When dividing 2 by 12, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 12

Step 2:
12 goes into 27 2 times with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 24 from 27 to get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 12

Advancing to step 3:
12 can be fit into 36 3 times, resulting in a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 23.0
If we subtract 36 from 36, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 12

Moving on to step 4:
12 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 230.0
If we subtract 0 from 0, we get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 12

Going ahead to step 5:
12 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 2300.0
Subtract 0 from 7 to get 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 12

Let's proceed to step 6:
12 can be fit into 70 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 23005.0
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.

Going ahead to step 7:
12 can be fit into 100 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 23005.8
The remainder is 4 after subtracting 96 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
40 divided by 12 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 23005.83
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 9:
When dividing 40 by 12, we get 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 23005.833
If we take 36 away from 40, we end up 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.

The quotient of the division is 23005.833, and the remainder is 0.0004.
