We divide 6843 by 54
We want to divide 6843 by 54.

Moving on to step 1:
6 divided by 54 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 54

Going ahead to step 2:
54 can be fit into 68 1 times, resulting in a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 54 from 68 and we're left with 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 54

Let's proceed to step 3:
54 can be fit into 144 2 times, resulting in a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 108 from 144, we get 36.
Fetch the next digit (3) from the dividend, attach it to 36 and continue: 363 / 54

On to step 4:
363 divided by 54 is 6 with a remainder of 39.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
If we take 324 away from 363, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 5:
If we divide 390 by 54, we get 7 and a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 126.7
Subtract 378 from 390 to 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 6:
120 divided by 54 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 126.72
Subtract 108 from 120 to 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 7:
54 goes into 120 2 times with a remainder of 12.
The next digit of our result is 2. 
Result so far: 126.722
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.

The quotient of the division is 126.722, and the remainder is 0.0012.
