We look at the division of 51708276 by 873 
We want to figure out the number of times 51708276 can be divided by 873.

Step 1:
When dividing 5 by 873, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 873

Let's proceed to step 2:
The number 873 fits into 51 0 times, leaving a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Fetch the next digit (7) from the dividend, attach it to 51 and continue: 517 / 873

Going ahead to step 3:
When dividing 517 by 873, we get 0 with a remainder of 517.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 517 leaves us with 517.
Take the next digit (0) from the dividend and append it to 517, then repeat: 5170 / 873

On to step 4:
If we divide 5170 by 873, we get 5 and a remainder of 805.
The next digit of our result is 5. 
Result so far: 5.0
If we take 4365 away from 5170, we end up with 805.
Grab the next digit (8) from the dividend, add it to 805, then carry on: 8058 / 873

Step 5:
When dividing 8058 by 873, we get 9 with a remainder of 201.
Put 9 as the next digit of the answer. 
Result so far: 59.0
Subtract 7857 from 8058 to get 201.
Append the next digit (2) from the dividend to 201 and continue with: 2012 / 873

On to step 6:
When dividing 2012 by 873, we get 2 with a remainder of 266.
Write down 2 as next digit of the result. 
Result so far: 592.0
Deduct 1746 from 2012 and we're left with 266.
Include the next digit (7) from the dividend after 266, then repeat: 2667 / 873

Advancing to step 7:
873 goes into 2667 3 times with a remainder of 48.
Write down 3 as next digit of the result. 
Result so far: 5923.0
Subtracting 2619 from 2667 leaves us with 48.
Append the next digit (6) from the dividend to 48 and continue with: 486 / 873

Going ahead to step 8:
873 can be fit into 486 0 times, resulting in a remainder of 486.
Record the quotient 0 as the next digit in the result. 
Result so far: 59230.0
If we take 0 away from 486, we end up with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Step 9:
4860 divided by 873 is 5 with a remainder of 495.
The number 5 becomes the next digit in our result. 
Result so far: 59230.5
Subtracting 4365 from 4860 leaves us with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Going ahead to step 10:
If we divide 4950 by 873, we get 5 and a remainder of 585.
Record the quotient 5 as the next digit in the result. 
Result so far: 59230.55
The remainder is 585 after subtracting 4365 from 4950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

The final result is 59230.55 with a remainder of 0.585.
