428304 ÷ 54 
We want to figure out the number of times 428304 can be divided by 54.

Step 1:
When dividing 4 by 54, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 54

Going ahead to step 2:
54 can be fit into 42 0 times, resulting in a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Fetch the next digit (8) from the dividend, attach it to 42 and continue: 428 / 54

Advancing to step 3:
When dividing 428 by 54, we get 7 with a remainder of 50.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 378 from 428 to get 50.
Bring next digit (3) of the dividend behind the 50 and repeat the process: 503 / 54

Going ahead to step 4:
When dividing 503 by 54, we get 9 with a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
Deduct 486 from 503 and we're left with 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 54

Let's proceed to step 5:
When dividing 170 by 54, we get 3 with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 793.0
Deduct 162 from 170 and we're left with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 54

On to step 6:
54 can be fit into 84 1 times, resulting in a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 7931.0
Subtract 54 from 84 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
When dividing 300 by 54, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 7931.5
If we take 270 away from 300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
When dividing 300 by 54, we get 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 7931.55
If we take 270 away from 300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 7931.55, and the remainder is 0.03.
