450543 ÷ 54 
We want to divide 450543 by 54.

On to step 1:
When dividing 4 by 54, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 54

Moving on to step 2:
45 divided by 54 is 0 with a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Fetch the next digit (0) from the dividend, attach it to 45 and continue: 450 / 54

On to step 3:
54 goes into 450 8 times with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 432 from 450 and we're left with 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 54

Going ahead to step 4:
When dividing 185 by 54, we get 3 with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 83.0
Subtract 162 from 185 to get 23.
Grab the next digit (4) from the dividend, add it to 23, then carry on: 234 / 54

Moving on to step 5:
The number 54 fits into 234 4 times, leaving a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 834.0
If we subtract 216 from 234, we get 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 54

Going ahead to step 6:
If we divide 183 by 54, we get 3 and a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 8343.0
Subtract 162 from 183 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
When dividing 210 by 54, we get 3 with a remainder of 48.
The next digit of our result is 3. 
Result so far: 8343.3
If we take 162 away from 210, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 8:
If we divide 480 by 54, we get 8 and a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 8343.38
Subtract 432 from 480 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
The number 54 fits into 480 8 times, leaving a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 8343.388
Subtracting 432 from 480 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 8343.388, and the remainder is 0.0048.
