We look at the division of 865775 by 51 
We want to divide 865775 by 51.

Let's proceed to step 1:
The number 51 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 51

Step 2:
When dividing 86 by 51, we get 1 with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 51 from 86 to get 35.
Bring next digit (5) of the dividend behind the 35 and repeat the process: 355 / 51

Step 3:
When dividing 355 by 51, we get 6 with a remainder of 49.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 306 from 355 leaves us with 49.
Bring next digit (7) of the dividend behind the 49 and repeat the process: 497 / 51

Let's proceed to step 4:
51 can be fit into 497 9 times, resulting in a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 169.0
Deduct 459 from 497 and we're left with 38.
Include the next digit (7) from the dividend after 38, then repeat: 387 / 51

Moving on to step 5:
The number 51 fits into 387 7 times, leaving a remainder of 30.
The next digit of our result is 7. 
Result so far: 1697.0
Subtracting 357 from 387 leaves us with 30.
Include the next digit (5) from the dividend after 30, then repeat: 305 / 51

Step 6:
When dividing 305 by 51, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 16975.0
If we take 255 away from 305, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 7:
500 divided by 51 is 9 with a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 16975.9
If we subtract 459 from 500, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 8:
51 goes into 410 8 times with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 16975.98
The remainder is 2 after subtracting 408 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
20 divided by 51 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 16975.98
If we take 0 away from 20, we end up 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.

Step 10:
51 goes into 200 3 times with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 16975.9803
The remainder is 47 after subtracting 153 from 200.
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 11:
The number 51 fits into 470 9 times, leaving a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 16975.98039
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.

On to step 12:
110 divided by 51 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 16975.980392
The remainder is 8 after subtracting 102 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
51 can be fit into 80 1 times, resulting in a remainder of 29.
The next digit of our result is 1. 
Result so far: 16975.9803921
The remainder is 29 after subtracting 51 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 14:
51 goes into 290 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 16975.98039215
If we take 255 away from 290, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 16975.98039215 and a remainder of 3.5e-08.
