Let's divide 187843 by 18
Let's see how many times 18 fits into 187843.

Moving on to step 1:
1 divided by 18 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 18

Going ahead to step 2:
When dividing 18 by 18, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 18 away from 18, we end up with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 18

Let's proceed to step 3:
When dividing 7 by 18, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 18

Going ahead to step 4:
78 divided by 18 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
Deduct 72 from 78 and we're left with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 18

Let's proceed to step 5:
If we divide 64 by 18, we get 3 and a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 1043.0
The remainder is 10 after subtracting 54 from 64.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 18

Advancing to step 6:
18 goes into 103 5 times with a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 10435.0
If we subtract 90 from 103, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
If we divide 130 by 18, we get 7 and a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 10435.7
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
18 goes into 40 2 times with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 10435.72
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
The number 18 fits into 40 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 10435.722
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 10435.722 with a remainder of 0.0004.
