291858 divided by 18 
We're looking to find how many times 18 goes into 291858.

Let's proceed to step 1:
When dividing 2 by 18, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 18

Moving on to step 2:
If we divide 29 by 18, we get 1 and a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 11 after subtracting 18 from 29.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 18

Step 3:
When dividing 111 by 18, we get 6 with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 16.0
The remainder is 3 after subtracting 108 from 111.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 18

On to step 4:
The number 18 fits into 38 2 times, leaving a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 162.0
If we take 36 away from 38, we end up with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 18

Advancing to step 5:
When dividing 25 by 18, we get 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1621.0
The remainder is 7 after subtracting 18 from 25.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 18

Moving on to step 6:
78 divided by 18 is 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 16214.0
Deduct 72 from 78 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.

Moving on to 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: 16214.3
Subtracting 54 from 60 leaves us 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.

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: 16214.33
Subtract 54 from 60 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.

The final outcome is 16214.33, with a leftover of 0.006.
