We divide 856589 by 18
We want to divide 856589 by 18.

Going ahead to step 1:
18 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 18

Moving on to step 2:
85 divided by 18 is 4 with a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 72 away from 85, we end up with 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 18

On to step 3:
When dividing 136 by 18, we get 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 47.0
The remainder is 10 after subtracting 126 from 136.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 18

On to step 4:
105 divided by 18 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 475.0
Deduct 90 from 105 and we're left with 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 18

Advancing to step 5:
The number 18 fits into 158 8 times, leaving a remainder of 14.
The next digit of our result is 8. 
Result so far: 4758.0
If we subtract 144 from 158, we get 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 18

Let's proceed to step 6:
If we divide 149 by 18, we get 8 and a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 47588.0
The remainder is 5 after subtracting 144 from 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
18 goes into 50 2 times with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 47588.2
If we take 36 away from 50, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
When dividing 140 by 18, we get 7 with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 47588.27
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
18 goes into 140 7 times with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 47588.277
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 47588.277 and a remainder of 0.0014.
