Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 999

Advancing to step 2:
The number 999 fits into 51 0 times, leaving a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Append the next digit (0) from the dividend to 51 and continue with: 510 / 999

On to step 3:
When dividing 510 by 999, we get 0 with a remainder of 510.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 510 and we're left with 510.
Include the next digit (4) from the dividend after 510, then repeat: 5104 / 999

Going ahead to step 4:
If we divide 5104 by 999, we get 5 and a remainder of 109.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 109 after subtracting 4995 from 5104.
Append the next digit (8) from the dividend to 109 and continue with: 1098 / 999

On to step 5:
If we divide 1098 by 999, we get 1 and a remainder of 99.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Subtracting 999 from 1098 leaves us with 99.
Fetch the next digit (6) from the dividend, attach it to 99 and continue: 996 / 999

Let's proceed to step 6:
999 can be fit into 996 0 times, resulting in a remainder of 996.
Put 0 as the next digit of the answer. 
Result so far: 510.0
The remainder is 996 after subtracting 0 from 996.
Take the next digit (9) from the dividend and append it to 996, then repeat: 9969 / 999

On to step 7:
999 can be fit into 9969 9 times, resulting in a remainder of 978.
Write down 9 as next digit of the result. 
Result so far: 5109.0
Deduct 8991 from 9969 and we're left with 978.
Fetch the next digit (4) from the dividend, attach it to 978 and continue: 9784 / 999

Let's proceed to step 8:
The number 999 fits into 9784 9 times, leaving a remainder of 793.
Put 9 as the next digit of the answer. 
Result so far: 51099.0
If we subtract 8991 from 9784, we get 793.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7930, and continue the process.

Step 9:
999 can be fit into 7930 7 times, resulting in a remainder of 937.
Write down 7 as next digit of the result. 
Result so far: 51099.7
The remainder is 937 after subtracting 6993 from 7930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9370, and continue the process.

On to step 10:
999 can be fit into 9370 9 times, resulting in a remainder of 379.
Put 9 as the next digit of the answer. 
Result so far: 51099.79
If we subtract 8991 from 9370, we get 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Going ahead to step 11:
When dividing 3790 by 999, we get 3 with a remainder of 793.
Use 3 as the next digit of our solution. 
Result so far: 51099.793
Subtract 2997 from 3790 to get 793.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7930, and continue the process.

Moving on to step 12:
7930 divided by 999 is 7 with a remainder of 937.
Record the quotient 7 as the next digit in the result. 
Result so far: 51099.7937
Subtract 6993 from 7930 to get 937.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9370, and continue the process.

On to step 13:
9370 divided by 999 is 9 with a remainder of 379.
Use 9 as the next digit of our solution. 
Result so far: 51099.79379
Subtract 8991 from 9370 to get 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Advancing to step 14:
If we divide 3790 by 999, we get 3 and a remainder of 793.
The next digit of our result is 3. 
Result so far: 51099.793793
Deduct 2997 from 3790 and we're left with 793.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7930, and continue the process.

Step 15:
If we divide 7930 by 999, we get 7 and a remainder of 937.
The number 7 becomes the next digit in our result. 
Result so far: 51099.7937937
Deduct 6993 from 7930 and we're left with 937.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9370, and continue the process.

Let's proceed to step 16:
If we divide 9370 by 999, we get 9 and a remainder of 379.
Use 9 as the next digit of our solution. 
Result so far: 51099.79379379
The remainder is 379 after subtracting 8991 from 9370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Our division results in 51099.79379379 with a remaining 3.79e-07.
