860505 ÷ 51 
Our goal is to divide 860505 by 51.

Let's proceed to step 1:
The number 51 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 51

Going ahead to step 2:
51 goes into 86 1 times with a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 51 from 86 and we're left with 35.
Take the next digit (0) from the dividend and append it to 35, then repeat: 350 / 51

Going ahead to step 3:
51 can be fit into 350 6 times, resulting in a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 306 from 350 leaves us with 44.
Append the next digit (5) from the dividend to 44 and continue with: 445 / 51

Let's proceed to step 4:
If we divide 445 by 51, we get 8 and a remainder of 37.
Put 8 as the next digit of the answer. 
Result so far: 168.0
The remainder is 37 after subtracting 408 from 445.
Include the next digit (0) from the dividend after 37, then repeat: 370 / 51

Moving on to step 5:
51 goes into 370 7 times with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 1687.0
The remainder is 13 after subtracting 357 from 370.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 51

Let's proceed to step 6:
The number 51 fits into 135 2 times, leaving a remainder of 33.
Write down 2 as next digit of the result. 
Result so far: 16872.0
Subtracting 102 from 135 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 7:
330 divided by 51 is 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 16872.6
Subtract 306 from 330 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 8:
When dividing 240 by 51, we get 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 16872.64
If we subtract 204 from 240, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
If we divide 360 by 51, we get 7 and a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 16872.647
Subtract 357 from 360 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 10:
If we divide 30 by 51, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 16872.647
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
If we divide 300 by 51, we get 5 and a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 16872.64705
The remainder is 45 after subtracting 255 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 12:
51 goes into 450 8 times with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 16872.647058
Subtracting 408 from 450 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 13:
51 goes into 420 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 16872.6470588
If we take 408 away from 420, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 16872.6470588 with a remaining 1.2e-07.
