We're dividing 858010 by 50 
We want to divide 858010 by 50.

On to step 1:
If we divide 8 by 50, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 50

Moving on to step 2:
When dividing 85 by 50, we get 1 with a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 50 from 85 and we're left with 35.
Append the next digit (8) from the dividend to 35 and continue with: 358 / 50

Step 3:
If we divide 358 by 50, we get 7 and a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 350 from 358, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 50

Going ahead to step 4:
80 divided by 50 is 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 171.0
Subtract 50 from 80 to get 30.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 50

Moving on to step 5:
301 divided by 50 is 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 1716.0
Deduct 300 from 301 and we're left with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 50

On to step 6:
50 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 17160.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
50 can be fit into 100 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 17160.2
If we take 100 away from 100, we end up 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.

Let's proceed to step 8:
0 divided by 50 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 17160.2
Subtracting 0 from 0 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.

Let's proceed to step 9:
50 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 17160.2
Subtracting 0 from 0 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.

In conclusion, the division gives 17160.2 with a balance of 0.0.
