We're dividing 50756144 by 12 
The aim is to understand the frequency of 12 in 50756144.

Moving on to step 1:
12 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 12

Advancing to step 2:
50 divided by 12 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 48 from 50 and we're left with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 12

Step 3:
27 divided by 12 is 2 with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 42.0
Deduct 24 from 27 and we're left with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 12

Let's proceed to step 4:
12 goes into 35 2 times with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 422.0
Deduct 24 from 35 and we're left with 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 12

Going ahead to step 5:
116 divided by 12 is 9 with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 4229.0
If we take 108 away from 116, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 12

Advancing to step 6:
When dividing 81 by 12, we get 6 with a remainder of 9.
The next digit of our result is 6. 
Result so far: 42296.0
If we take 72 away from 81, we end up with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 12

Moving on to step 7:
12 can be fit into 94 7 times, resulting in a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 422967.0
If we subtract 84 from 94, we get 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 12

Let's proceed to step 8:
12 can be fit into 104 8 times, resulting in a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 4229678.0
Subtracting 96 from 104 leaves us 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.

Moving on to step 9:
12 goes into 80 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 4229678.6
If we subtract 72 from 80, we get 8.
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.
Write down 6 as next digit of the result. 
Result so far: 4229678.66
If we subtract 72 from 80, we get 8.
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 result is 4229678.66 with a remainder of 0.008.
