We look at the division of 385484 by 12 
Let's see how many times 12 fits into 385484.

Moving on to step 1:
12 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 12

Step 2:
If we divide 38 by 12, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 36 away from 38, we end up with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 12

Step 3:
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: 32.0
Deduct 24 from 25 and we're left with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 12

Going ahead to step 4:
12 goes into 14 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 321.0
Deduct 12 from 14 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 12

Advancing to step 5:
When dividing 28 by 12, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 3212.0
The remainder is 4 after subtracting 24 from 28.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 12

Moving on to step 6:
When dividing 44 by 12, we get 3 with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 32123.0
Deduct 36 from 44 and we're left 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.

Advancing to step 7:
When dividing 80 by 12, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 32123.6
Deduct 72 from 80 and we're left 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 8:
80 divided by 12 is 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 32123.66
Subtracting 72 from 80 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.

The final outcome is 32123.66, with a leftover of 0.008.
