We're dividing 39003 by 54 
We want to divide 39003 by 54.

Advancing to step 1:
If we divide 3 by 54, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 54

Let's proceed to step 2:
If we divide 39 by 54, we get 0 and a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 54

On to step 3:
54 goes into 390 7 times with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 378 from 390 to get 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 54

Moving on to step 4:
When dividing 120 by 54, we get 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 72.0
If we take 108 away from 120, we end up with 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 54

Step 5:
When dividing 123 by 54, we get 2 with a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 722.0
The remainder is 15 after subtracting 108 from 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 6:
54 goes into 150 2 times with a remainder of 42.
The next digit of our result is 2. 
Result so far: 722.2
Deduct 108 from 150 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 7:
When dividing 420 by 54, we get 7 with a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 722.27
Deduct 378 from 420 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 8:
54 can be fit into 420 7 times, resulting in a remainder of 42.
The next digit of our result is 7. 
Result so far: 722.277
If we take 378 away from 420, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 722.277 with a remaining 0.0042.
