505886 ÷ 51 
We're looking to find how many times 51 goes into 505886.

Going ahead to step 1:
The number 51 fits into 5 0 times, leaving 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 (0) from the dividend, attach it to 5 and continue: 50 / 51

On to step 2:
When dividing 50 by 51, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Fetch the next digit (5) from the dividend, attach it to 50 and continue: 505 / 51

Let's proceed to step 3:
51 goes into 505 9 times with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 459 away from 505, we end up with 46.
Include the next digit (8) from the dividend after 46, then repeat: 468 / 51

Advancing to step 4:
The number 51 fits into 468 9 times, leaving a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 99.0
The remainder is 9 after subtracting 459 from 468.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 51

Advancing to step 5:
98 divided by 51 is 1 with a remainder of 47.
The next digit of our result is 1. 
Result so far: 991.0
The remainder is 47 after subtracting 51 from 98.
Bring next digit (6) of the dividend behind the 47 and repeat the process: 476 / 51

Let's proceed to step 6:
The number 51 fits into 476 9 times, leaving a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 9919.0
Deduct 459 from 476 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
51 goes into 170 3 times with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 9919.3
The remainder is 17 after subtracting 153 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 8:
The number 51 fits into 170 3 times, leaving a remainder of 17.
The next digit of our result is 3. 
Result so far: 9919.33
The remainder is 17 after subtracting 153 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Our division results in 9919.33 with a remaining 0.017.
