We're dividing 24423673 by 12 
The aim is to understand the frequency of 12 in 24423673.

On to step 1:
12 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 12

Going ahead to step 2:
The number 12 fits into 24 2 times, leaving 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.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 12

Advancing to step 3:
If we divide 4 by 12, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 4 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 12

Advancing to step 4:
The number 12 fits into 42 3 times, leaving a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 203.0
The remainder is 6 after subtracting 36 from 42.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 12

Let's proceed to step 5:
12 can be fit into 63 5 times, resulting in a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 2035.0
The remainder is 3 after subtracting 60 from 63.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 12

On to step 6:
When dividing 36 by 12, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 20353.0
Deduct 36 from 36 and we're left with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 12

Moving on to step 7:
The number 12 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 203530.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 12

Moving on to step 8:
12 goes into 73 6 times with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 2035306.0
Subtract 72 from 73 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
If we divide 10 by 12, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 2035306.0
If we take 0 away from 10, we end up 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.

Step 10:
12 can be fit into 100 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 2035306.08
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.

Going ahead to step 11:
40 divided by 12 is 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 2035306.083
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.

On to step 12:
When dividing 40 by 12, we get 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 2035306.0833
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 final result is 2035306.0833 with a remainder of 4e-05.
