857001 ÷ 18 
We're looking to find how many times 18 goes into 857001.

Going ahead to step 1:
18 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 18

Let's proceed to step 2:
If we divide 85 by 18, we get 4 and a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 72 from 85 to get 13.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 18

Let's proceed to step 3:
18 goes into 137 7 times with a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 47.0
Deduct 126 from 137 and we're left with 11.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 18

Step 4:
110 divided by 18 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 476.0
Subtract 108 from 110 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 18

Step 5:
The number 18 fits into 20 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 4761.0
The remainder is 2 after subtracting 18 from 20.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 18

Moving on to step 6:
18 can be fit into 21 1 times, resulting in a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 47611.0
If we take 18 away from 21, 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.

Moving on to step 7:
18 goes into 30 1 times with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 47611.1
If we subtract 18 from 30, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
If we divide 120 by 18, we get 6 and a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 47611.16
If we take 108 away from 120, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
When dividing 120 by 18, we get 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 47611.166
If we subtract 108 from 120, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 47611.166, with a leftover of 0.0012.
