Let's divide 243007 by 12
The aim is to understand the frequency of 12 in 243007.

On to step 1:
2 divided by 12 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 12

Let's proceed to step 2:
12 can be fit into 24 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 24 from 24 to get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 12

On to step 3:
The number 12 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 20.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 12

Going ahead to step 4:
12 can be fit into 30 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 202.0
Deduct 24 from 30 and we're left with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 12

Let's proceed to step 5:
12 can be fit into 60 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 2025.0
If we take 60 away from 60, we end up with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 12

Going ahead to step 6:
If we divide 7 by 12, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 20250.0
If we subtract 0 from 7, we get 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.
Write down 5 as next digit of the result. 
Result so far: 20250.5
The remainder is 10 after subtracting 60 from 70.
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:
If we divide 100 by 12, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 20250.58
Subtract 96 from 100 to 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.

Let's proceed to step 9:
If we divide 40 by 12, we get 3 and a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 20250.583
Subtract 36 from 40 to 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.

Let's proceed to step 10:
12 goes into 40 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 20250.5833
Subtracting 36 from 40 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.

The quotient of the division is 20250.5833, and the remainder is 4e-05.
