Subtracting 0 from 5 leaves us with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 999

On to step 2:
999 goes into 54 0 times with a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Bring next digit (4) of the dividend behind the 54 and repeat the process: 544 / 999

Moving on to step 3:
The number 999 fits into 544 0 times, leaving a remainder of 544.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 544 to get 544.
Fetch the next digit (1) from the dividend, attach it to 544 and continue: 5441 / 999

Going ahead to step 4:
999 can be fit into 5441 5 times, resulting in a remainder of 446.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 4995 from 5441 to get 446.
Take the next digit (5) from the dividend and append it to 446, then repeat: 4465 / 999

Step 5:
999 can be fit into 4465 4 times, resulting in a remainder of 469.
Put 4 as the next digit of the answer. 
Result so far: 54.0
If we subtract 3996 from 4465, we get 469.
Fetch the next digit (8) from the dividend, attach it to 469 and continue: 4698 / 999

On to step 6:
When dividing 4698 by 999, we get 4 with a remainder of 702.
Use 4 as the next digit of our solution. 
Result so far: 544.0
If we subtract 3996 from 4698, we get 702.
Bring next digit (0) of the dividend behind the 702 and repeat the process: 7020 / 999

Step 7:
If we divide 7020 by 999, we get 7 and a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 5447.0
Subtract 6993 from 7020 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 8:
999 goes into 270 0 times with a remainder of 270.
The next digit of our result is 0. 
Result so far: 5447.0
If we take 0 away from 270, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 9:
999 goes into 2700 2 times with a remainder of 702.
Use 2 as the next digit of our solution. 
Result so far: 5447.02
Deduct 1998 from 2700 and we're left with 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

Step 10:
If we divide 7020 by 999, we get 7 and a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 5447.027
If we take 6993 away from 7020, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 11:
The number 999 fits into 270 0 times, leaving a remainder of 270.
The number 0 becomes the next digit in our result. 
Result so far: 5447.027
Deduct 0 from 270 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 12:
2700 divided by 999 is 2 with a remainder of 702.
The number 2 becomes the next digit in our result. 
Result so far: 5447.02702
If we subtract 1998 from 2700, we get 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

Advancing to step 13:
When dividing 7020 by 999, we get 7 with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 5447.027027
Deduct 6993 from 7020 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 14:
270 divided by 999 is 0 with a remainder of 270.
The next digit of our result is 0. 
Result so far: 5447.027027
Subtracting 0 from 270 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 15:
999 can be fit into 2700 2 times, resulting in a remainder of 702.
The next digit of our result is 2. 
Result so far: 5447.02702702
Subtracting 1998 from 2700 leaves us with 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

The quotient of the division is 5447.02702702, and the remainder is 7.02e-07.
