We're dividing 48379275 by 12 
We want to figure out the number of times 48379275 can be divided by 12.

Going ahead to step 1:
12 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 12

Step 2:
12 goes into 48 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 48 from 48 leaves us with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 12

Step 3:
If we divide 3 by 12, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
If we subtract 0 from 3, we get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 12

On to step 4:
37 divided by 12 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 403.0
Deduct 36 from 37 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 12

Going ahead to step 5:
The number 12 fits into 19 1 times, leaving a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 4031.0
Subtracting 12 from 19 leaves us with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 12

Moving on to step 6:
72 divided by 12 is 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 40316.0
Deduct 72 from 72 and we're left with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 12

Advancing to step 7:
7 divided by 12 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 403160.0
If we subtract 0 from 7, we get 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 12

Step 8:
The number 12 fits into 75 6 times, leaving a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 4031606.0
Subtracting 72 from 75 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
30 divided by 12 is 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 4031606.2
Subtracting 24 from 30 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 4031606.25
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
0 divided by 12 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4031606.25
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4031606.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 4031606.25 with a remaining 0.0.
