54648 divided by 3 
We're looking to find how many times 3 goes into 54648.

Going ahead to step 1:
When dividing 5 by 3, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 2 after subtracting 3 from 5.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 3

Let's proceed to step 2:
3 can be fit into 24 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 24 from 24 and we're left with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 3

Let's proceed to step 3:
The number 3 fits into 6 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 182.0
If we take 6 away from 6, we end up with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 3

Going ahead to step 4:
3 can be fit into 4 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1821.0
If we subtract 3 from 4, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 3

Let's proceed to step 5:
3 can be fit into 18 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 18216.0
Deduct 18 from 18 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 6:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18216.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
0 divided by 3 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18216.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 18216.0, with a leftover of 0.0.
