629539 divided by 12 
The aim is to understand the frequency of 12 in 629539.

Going ahead to step 1:
The number 12 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 12

On to step 2:
62 divided by 12 is 5 with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 60 from 62 leaves us with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 12

On to step 3:
29 divided by 12 is 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
Subtracting 24 from 29 leaves us with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 12

Let's proceed to step 4:
12 can be fit into 55 4 times, resulting in a remainder of 7.
The next digit of our result is 4. 
Result so far: 524.0
Deduct 48 from 55 and we're left with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 12

Let's proceed to step 5:
12 goes into 73 6 times with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 5246.0
Subtracting 72 from 73 leaves us with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 12

Advancing to step 6:
19 divided by 12 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 52461.0
Subtracting 12 from 19 leaves us 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:
12 can be fit into 70 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 52461.5
If we subtract 60 from 70, we get 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 8:
If we divide 100 by 12, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 52461.58
If we subtract 96 from 100, 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.

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: 52461.583
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.

Advancing to step 10:
The number 12 fits into 40 3 times, leaving a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 52461.5833
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.

After the division, we end up with 52461.5833 and a remainder of 4e-05.
