Let's divide 624454 by 12
The aim is to understand the frequency of 12 in 624454.

Let's proceed to step 1:
12 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 12

Step 2:
12 goes into 62 5 times with a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 2 after subtracting 60 from 62.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 12

Moving on to step 3:
12 goes into 24 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 52.0
Subtracting 24 from 24 leaves us with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 12

Advancing to step 4:
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: 520.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 12

On to step 5:
45 divided by 12 is 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 5203.0
The remainder is 9 after subtracting 36 from 45.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 12

Moving on to step 6:
If we divide 94 by 12, we get 7 and a remainder of 10.
The next digit of our result is 7. 
Result so far: 52037.0
Deduct 84 from 94 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.

Let's proceed to step 7:
The number 12 fits into 100 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 52037.8
If we take 96 away from 100, 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.

On to step 8:
12 can be fit into 40 3 times, resulting in a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 52037.83
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.

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: 52037.833
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.

Our division results in 52037.833 with a remaining 0.0004.
