We're dividing 428508 by 54 
We're looking to find how many times 54 goes into 428508.

Step 1:
If we divide 4 by 54, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 54

Moving on to step 2:
42 divided by 54 is 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Take the next digit (8) from the dividend and append it to 42, then repeat: 428 / 54

Moving on to step 3:
54 goes into 428 7 times with a remainder of 50.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 378 from 428 and we're left with 50.
Bring next digit (5) of the dividend behind the 50 and repeat the process: 505 / 54

On to step 4:
If we divide 505 by 54, we get 9 and a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 79.0
Subtracting 486 from 505 leaves us with 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 54

Let's proceed to step 5:
When dividing 190 by 54, we get 3 with a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 793.0
If we subtract 162 from 190, we get 28.
Take the next digit (8) from the dividend and append it to 28, then repeat: 288 / 54

Moving on to step 6:
The number 54 fits into 288 5 times, leaving a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 7935.0
If we subtract 270 from 288, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
If we divide 180 by 54, we get 3 and a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 7935.3
The remainder is 18 after subtracting 162 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
The number 54 fits into 180 3 times, leaving a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 7935.33
Deduct 162 from 180 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 7935.33, and the remainder is 0.018.
