Let's divide 863392 by 51
We want to figure out the number of times 863392 can be divided by 51.

Let's proceed to step 1:
51 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 51

Advancing to step 2:
The number 51 fits into 86 1 times, leaving a remainder of 35.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 35 after subtracting 51 from 86.
Grab the next digit (3) from the dividend, add it to 35, then carry on: 353 / 51

Advancing to step 3:
51 can be fit into 353 6 times, resulting in a remainder of 47.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 47 after subtracting 306 from 353.
Bring next digit (3) of the dividend behind the 47 and repeat the process: 473 / 51

Advancing to step 4:
The number 51 fits into 473 9 times, leaving a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 169.0
Deduct 459 from 473 and we're left with 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 51

Moving on to step 5:
51 goes into 149 2 times with a remainder of 47.
Use 2 as the next digit of our solution. 
Result so far: 1692.0
If we subtract 102 from 149, we get 47.
Take the next digit (2) from the dividend and append it to 47, then repeat: 472 / 51

Step 6:
51 can be fit into 472 9 times, resulting in a remainder of 13.
The next digit of our result is 9. 
Result so far: 16929.0
Subtract 459 from 472 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
51 goes into 130 2 times with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 16929.2
If we subtract 102 from 130, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 8:
280 divided by 51 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 16929.25
Subtract 255 from 280 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
51 can be fit into 250 4 times, resulting in a remainder of 46.
The next digit of our result is 4. 
Result so far: 16929.254
The remainder is 46 after subtracting 204 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 10:
The number 51 fits into 460 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 16929.2549
Subtract 459 from 460 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
The number 51 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 16929.2549
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
If we divide 100 by 51, we get 1 and a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 16929.254901
Subtracting 51 from 100 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 13:
51 can be fit into 490 9 times, resulting in a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 16929.2549019
The remainder is 31 after subtracting 459 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 14:
51 can be fit into 310 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 16929.25490196
The remainder is 4 after subtracting 306 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 16929.25490196 with a remaining 4e-09.
