Let's divide 380905 by 12
We want to divide 380905 by 12.

Advancing to step 1:
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: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 12

Moving on to step 2:
12 can be fit into 38 3 times, resulting in a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 2 after subtracting 36 from 38.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 12

Advancing to step 3:
12 can be fit into 20 1 times, resulting in a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 31.0
The remainder is 8 after subtracting 12 from 20.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 12

Let's proceed to step 4:
The number 12 fits into 89 7 times, leaving a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 317.0
Subtracting 84 from 89 leaves us with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 12

On to step 5:
If we divide 50 by 12, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 3174.0
Deduct 48 from 50 and we're left with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 12

Advancing to step 6:
The number 12 fits into 25 2 times, leaving a remainder of 1.
The next digit of our result is 2. 
Result so far: 31742.0
If we take 24 away from 25, we end up 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.

On to step 7:
The number 12 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 31742.0
Deduct 0 from 10 and we're left 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.

Let's proceed to step 8:
100 divided by 12 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 31742.08
If we subtract 96 from 100, 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.

Advancing to step 9:
12 goes into 40 3 times with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 31742.083
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 10:
12 goes into 40 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 31742.0833
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 result is 31742.0833 with a remainder of 4e-05.
