We look at the division of 859518 by 5 
We're looking to find how many times 5 goes into 859518.

Going ahead to step 1:
The number 5 fits into 8 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 5 from 8 leaves us with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 5

Step 2:
35 divided by 5 is 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 35 from 35 leaves us with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 5

Let's proceed to step 3:
The number 5 fits into 9 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 171.0
Subtract 5 from 9 to get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 5

On to step 4:
If we divide 45 by 5, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 1719.0
Subtracting 45 from 45 leaves us with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 5

On to step 5:
5 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 17190.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 5

Advancing to step 6:
18 divided by 5 is 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 171903.0
If we take 15 away from 18, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
The number 5 fits into 30 6 times, leaving a remainder of 0.
The next digit of our result is 6. 
Result so far: 171903.6
Deduct 30 from 30 and we're left 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:
5 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 171903.6
Deduct 0 from 0 and we're left 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 9:
5 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 171903.6
Deduct 0 from 0 and we're left 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.

Our division results in 171903.6 with a remaining 0.0.
