We look at the division of 820919 by 51 
We're looking to find how many times 51 goes into 820919.

Step 1:
When dividing 8 by 51, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 51

Advancing to step 2:
82 divided by 51 is 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 51 from 82 and we're left with 31.
Append the next digit (0) from the dividend to 31 and continue with: 310 / 51

Moving on to step 3:
The number 51 fits into 310 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 16.0
Subtract 306 from 310 to get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 51

Step 4:
51 can be fit into 49 0 times, resulting in a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 160.0
The remainder is 49 after subtracting 0 from 49.
Fetch the next digit (1) from the dividend, attach it to 49 and continue: 491 / 51

Advancing to step 5:
The number 51 fits into 491 9 times, leaving a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 1609.0
Subtract 459 from 491 to get 32.
Bring next digit (9) of the dividend behind the 32 and repeat the process: 329 / 51

Advancing to step 6:
329 divided by 51 is 6 with a remainder of 23.
The number 6 becomes the next digit in our result. 
Result so far: 16096.0
Deduct 306 from 329 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
51 can be fit into 230 4 times, resulting in a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 16096.4
If we take 204 away from 230, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 8:
When dividing 260 by 51, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 16096.45
Subtract 255 from 260 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
The number 51 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 16096.45
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
51 can be fit into 500 9 times, resulting in a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 16096.4509
Deduct 459 from 500 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 11:
The number 51 fits into 410 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 16096.45098
If we take 408 away from 410, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 12:
The number 51 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 16096.45098
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
If we divide 200 by 51, we get 3 and a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 16096.4509803
Deduct 153 from 200 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 14:
When dividing 470 by 51, we get 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 16096.45098039
If we subtract 459 from 470, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 16096.45098039 with a remainder of 1.1e-08.
