We look at the division of 138025 by 12 
Let's see how many times 12 fits into 138025.

Going ahead to step 1:
12 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 12

On to step 2:
12 can be fit into 13 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 12 from 13 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 12

Moving on to step 3:
If we divide 18 by 12, we get 1 and a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 12 from 18, we get 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 12

Let's proceed to step 4:
If we divide 60 by 12, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 115.0
If we take 60 away from 60, we end up with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 12

Going ahead to step 5:
When dividing 2 by 12, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 1150.0
Subtract 0 from 2 to get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 12

Let's proceed to step 6:
The number 12 fits into 25 2 times, leaving a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 11502.0
Subtracting 24 from 25 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
If we divide 10 by 12, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 11502.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
When dividing 100 by 12, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 11502.08
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.

Advancing to step 9:
When dividing 40 by 12, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 11502.083
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.

Let's proceed to step 10:
When dividing 40 by 12, we get 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 11502.0833
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.

The final result is 11502.0833 with a remainder of 4e-05.
