We're dividing 857602 by 18 
We want to divide 857602 by 18.

Step 1:
18 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 18

Advancing to step 2:
18 goes into 85 4 times with a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 13 after subtracting 72 from 85.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 18

On to step 3:
18 can be fit into 137 7 times, resulting in a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 47.0
If we subtract 126 from 137, we get 11.
Append the next digit (6) from the dividend to 11 and continue with: 116 / 18

Step 4:
18 goes into 116 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 476.0
Subtract 108 from 116 to get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 18

Going ahead to step 5:
18 goes into 80 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 4764.0
If we take 72 away from 80, we end up with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 18

Advancing to step 6:
82 divided by 18 is 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 47644.0
Deduct 72 from 82 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
The number 18 fits into 100 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 47644.5
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
100 divided by 18 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 47644.55
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 47644.55, with a leftover of 0.01.
