We divide 860190 by 18
We're looking to find how many times 18 goes into 860190.

Moving on to step 1:
18 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 18

Going ahead to step 2:
If we divide 86 by 18, we get 4 and a remainder of 14.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 72 from 86 leaves us with 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 18

Step 3:
18 goes into 140 7 times with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 47.0
Subtract 126 from 140 to get 14.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 18

Let's proceed to step 4:
When dividing 141 by 18, we get 7 with a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 477.0
If we take 126 away from 141, we end up with 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 18

Going ahead to step 5:
If we divide 159 by 18, we get 8 and a remainder of 15.
The next digit of our result is 8. 
Result so far: 4778.0
Subtracting 144 from 159 leaves us with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 18

Advancing to step 6:
When dividing 150 by 18, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 47788.0
Subtract 144 from 150 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
When dividing 60 by 18, we get 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 47788.3
If we subtract 54 from 60, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
If we divide 60 by 18, we get 3 and a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 47788.33
Deduct 54 from 60 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 47788.33, with a leftover of 0.006.
