816493 ÷ 51 
We're looking to find how many times 51 goes into 816493.

Step 1:
51 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 51

Advancing to step 2:
If we divide 81 by 51, we get 1 and a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 30 after subtracting 51 from 81.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 51

Let's proceed to step 3:
When dividing 306 by 51, we get 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 0 after subtracting 306 from 306.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 51

Advancing to step 4:
The number 51 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 160.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 51

Advancing to step 5:
49 divided by 51 is 0 with a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 1600.0
If we take 0 away from 49, we end up with 49.
Include the next digit (3) from the dividend after 49, then repeat: 493 / 51

Moving on to step 6:
The number 51 fits into 493 9 times, leaving a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 16009.0
Subtracting 459 from 493 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 7:
If we divide 340 by 51, we get 6 and a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 16009.6
If we subtract 306 from 340, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 8:
51 goes into 340 6 times with a remainder of 34.
The next digit of our result is 6. 
Result so far: 16009.66
Subtract 306 from 340 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final result is 16009.66 with a remainder of 0.034.
