We're dividing 54845547 by 999 
We want to divide 54845547 by 999.

On to step 1:
The number 999 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 999

Moving on to step 2:
The number 999 fits into 54 0 times, leaving a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Bring next digit (8) of the dividend behind the 54 and repeat the process: 548 / 999

Moving on to step 3:
999 can be fit into 548 0 times, resulting in a remainder of 548.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 548 to get 548.
Fetch the next digit (4) from the dividend, attach it to 548 and continue: 5484 / 999

Advancing to step 4:
If we divide 5484 by 999, we get 5 and a remainder of 489.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 4995 from 5484 to get 489.
Include the next digit (5) from the dividend after 489, then repeat: 4895 / 999

Moving on to step 5:
999 goes into 4895 4 times with a remainder of 899.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
If we take 3996 away from 4895, we end up with 899.
Bring next digit (5) of the dividend behind the 899 and repeat the process: 8995 / 999

Advancing to step 6:
8995 divided by 999 is 9 with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 549.0
Subtracting 8991 from 8995 leaves us with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 999

Let's proceed to step 7:
When dividing 44 by 999, we get 0 with a remainder of 44.
The next digit of our result is 0. 
Result so far: 5490.0
Deduct 0 from 44 and we're left with 44.
Fetch the next digit (7) from the dividend, attach it to 44 and continue: 447 / 999

Step 8:
999 can be fit into 447 0 times, resulting in a remainder of 447.
Use 0 as the next digit of our solution. 
Result so far: 54900.0
Subtract 0 from 447 to get 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Step 9:
When dividing 4470 by 999, we get 4 with a remainder of 474.
Write down 4 as next digit of the result. 
Result so far: 54900.4
If we subtract 3996 from 4470, we get 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Moving on to step 10:
999 goes into 4740 4 times with a remainder of 744.
The number 4 becomes the next digit in our result. 
Result so far: 54900.44
Deduct 3996 from 4740 and we're left with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

The final outcome is 54900.44, with a leftover of 0.744.
