405303 ÷ 54 
Let's see how many times 54 fits into 405303.

On to step 1:
54 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 54

Moving on to step 2:
When dividing 40 by 54, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 54

Moving on to step 3:
The number 54 fits into 405 7 times, leaving a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 378 from 405 and we're left with 27.
Grab the next digit (3) from the dividend, add it to 27, then carry on: 273 / 54

Let's proceed to step 4:
If we divide 273 by 54, we get 5 and a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
Subtract 270 from 273 to get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 54

Going ahead to step 5:
54 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 750.0
If we take 0 away from 30, we end up with 30.
Fetch the next digit (3) from the dividend, attach it to 30 and continue: 303 / 54

Step 6:
If we divide 303 by 54, we get 5 and a remainder of 33.
Write down 5 as next digit of the result. 
Result so far: 7505.0
The remainder is 33 after subtracting 270 from 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 7:
54 goes into 330 6 times with a remainder of 6.
The next digit of our result is 6. 
Result so far: 7505.6
The remainder is 6 after subtracting 324 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
54 can be fit into 60 1 times, resulting in a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 7505.61
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
54 can be fit into 60 1 times, resulting in a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 7505.611
Subtracting 54 from 60 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 7505.611, and the remainder is 0.0006.
