We're dividing 863691 by 5 
Let's see how many times 5 fits into 863691.

Going ahead to step 1:
5 can be fit into 8 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 5 away from 8, we end up with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 5

Going ahead to step 2:
36 divided by 5 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 17.0
If we subtract 35 from 36, we get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 5

Advancing to step 3:
13 divided by 5 is 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 172.0
If we subtract 10 from 13, we get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 5

Moving on to step 4:
5 goes into 36 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 1727.0
Deduct 35 from 36 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 5

Going ahead to step 5:
5 goes into 19 3 times with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 17273.0
Subtract 15 from 19 to get 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 5

On to step 6:
If we divide 41 by 5, we get 8 and a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 172738.0
Deduct 40 from 41 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
If we divide 10 by 5, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 172738.2
Subtracting 10 from 10 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 5 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 172738.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
If we divide 0 by 5, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 172738.2
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 172738.2, and the remainder is 0.0.
