Let's divide 631073 by 12
The aim is to understand the frequency of 12 in 631073.

Advancing to step 1:
When dividing 6 by 12, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 12

Going ahead to step 2:
If we divide 63 by 12, we get 5 and a remainder of 3.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 60 from 63, we get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 12

Step 3:
12 can be fit into 31 2 times, resulting in a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 52.0
The remainder is 7 after subtracting 24 from 31.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 12

Advancing to step 4:
When dividing 70 by 12, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 525.0
Subtracting 60 from 70 leaves us with 10.
Fetch the next digit (7) from the dividend, attach it to 10 and continue: 107 / 12

Let's proceed to step 5:
The number 12 fits into 107 8 times, leaving a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 5258.0
Subtracting 96 from 107 leaves us with 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 12

On to step 6:
If we divide 113 by 12, we get 9 and a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 52589.0
The remainder is 5 after subtracting 108 from 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
50 divided by 12 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 52589.4
The remainder is 2 after subtracting 48 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
12 can be fit into 20 1 times, resulting in a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 52589.41
Deduct 12 from 20 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
When dividing 80 by 12, we get 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 52589.416
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
12 can be fit into 80 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 52589.4166
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 52589.4166, with a leftover of 8e-05.
