We divide 54089 by 12
Let's see how many times 12 fits into 54089.

On to step 1:
5 divided by 12 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 12

Let's proceed to step 2:
When dividing 54 by 12, we get 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 48 from 54 leaves us with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 12

Going ahead to step 3:
12 goes into 60 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtract 60 from 60 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 12

Step 4:
8 divided by 12 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 450.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 12

Moving on to step 5:
12 can be fit into 89 7 times, resulting in a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 4507.0
If we subtract 84 from 89, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 6:
50 divided by 12 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 4507.4
The remainder is 2 after subtracting 48 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
If we divide 20 by 12, we get 1 and a remainder of 8.
The next digit of our result is 1. 
Result so far: 4507.41
Subtracting 12 from 20 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.

Step 8:
80 divided by 12 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 4507.416
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.

Step 9:
80 divided by 12 is 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 4507.4166
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.

Our division results in 4507.4166 with a remaining 8e-05.
