We divide 855910 by 5
We want to figure out the number of times 855910 can be divided by 5.

Step 1:
If we divide 8 by 5, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 5 from 8 to get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 5

Step 2:
5 can be fit into 35 7 times, resulting in a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtracting 35 from 35 leaves us with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 5

On to step 3:
If we divide 5 by 5, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 171.0
If we subtract 5 from 5, we get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 5

Let's proceed to step 4:
5 goes into 9 1 times with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1711.0
The remainder is 4 after subtracting 5 from 9.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 5

Going ahead to step 5:
5 can be fit into 41 8 times, resulting in a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 17118.0
Subtracting 40 from 41 leaves us with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 5

On to step 6:
When dividing 10 by 5, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 171182.0
Subtract 10 from 10 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.

Moving on to step 7:
When dividing 0 by 5, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 171182.0
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.

Step 8:
When dividing 0 by 5, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 171182.0
If we subtract 0 from 0, we 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.

Our division results in 171182.0 with a remaining 0.0.
