Let's divide 250738 by 12
The aim is to understand the frequency of 12 in 250738.

Going ahead to step 1:
12 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 12

Let's proceed to step 2:
When dividing 25 by 12, we get 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
If we take 24 away from 25, we end up with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 12

Moving on to step 3:
If we divide 10 by 12, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Deduct 0 from 10 and we're left with 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 12

Advancing to step 4:
12 can be fit into 107 8 times, resulting in a remainder of 11.
The next digit of our result is 8. 
Result so far: 208.0
If we subtract 96 from 107, we get 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 12

Let's proceed to step 5:
When dividing 113 by 12, we get 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 2089.0
Subtract 108 from 113 to get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 12

Going ahead to step 6:
12 goes into 58 4 times with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 20894.0
Subtracting 48 from 58 leaves us 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 7:
When dividing 100 by 12, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 20894.8
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.

Step 8:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 20894.83
If we subtract 36 from 40, 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.

Going ahead to step 9:
40 divided by 12 is 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 20894.833
If we subtract 36 from 40, 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.

The quotient of the division is 20894.833, and the remainder is 0.0004.
