We're dividing 49038082 by 12 
The aim is to understand the frequency of 12 in 49038082.

Advancing to step 1:
The number 12 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 12

Moving on to step 2:
12 can be fit into 49 4 times, resulting in a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 48 from 49 and we're left with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 12

On to step 3:
The number 12 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtract 0 from 10 to get 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 12

Advancing to step 4:
If we divide 103 by 12, we get 8 and a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 408.0
If we take 96 away from 103, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 12

On to step 5:
The number 12 fits into 78 6 times, leaving a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 4086.0
Subtract 72 from 78 to get 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 12

Going ahead to step 6:
When dividing 60 by 12, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 40865.0
Subtracting 60 from 60 leaves us with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 12

Advancing to step 7:
If we divide 8 by 12, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 408650.0
If we take 0 away from 8, we end up with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 12

Advancing to step 8:
When dividing 82 by 12, we get 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 4086506.0
If we take 72 away from 82, we end up 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.

Moving on to step 9:
12 goes into 100 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 4086506.8
Deduct 96 from 100 and we're left 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 10:
The number 12 fits into 40 3 times, leaving a remainder of 4.
The next digit of our result is 3. 
Result so far: 4086506.83
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.

Going ahead to step 11:
If we divide 40 by 12, we get 3 and a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 4086506.833
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 final outcome is 4086506.833, with a leftover of 0.0004.
