We're dividing 311843 by 18 
We're looking to find how many times 18 goes into 311843.

Moving on to step 1:
When dividing 3 by 18, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 18

Step 2:
31 divided by 18 is 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 18 from 31, we get 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 18

Let's proceed to step 3:
The number 18 fits into 131 7 times, leaving a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 17.0
The remainder is 5 after subtracting 126 from 131.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 18

Step 4:
58 divided by 18 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 173.0
The remainder is 4 after subtracting 54 from 58.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 18

Let's proceed to step 5:
The number 18 fits into 44 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 1732.0
Subtracting 36 from 44 leaves us with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 18

On to step 6:
83 divided by 18 is 4 with a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 17324.0
Subtract 72 from 83 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
110 divided by 18 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 17324.6
If we take 108 away from 110, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
If we divide 20 by 18, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 17324.61
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
18 can be fit into 20 1 times, resulting in a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 17324.611
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 17324.611, and the remainder is 0.0002.
