542168 ÷ 81 
Our goal is to divide 542168 by 81.

Let's proceed to step 1:
81 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 81

Advancing to step 2:
The number 81 fits into 54 0 times, leaving a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Include the next digit (2) from the dividend after 54, then repeat: 542 / 81

Advancing to step 3:
81 can be fit into 542 6 times, resulting in a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 486 away from 542, we end up with 56.
Take the next digit (1) from the dividend and append it to 56, then repeat: 561 / 81

Step 4:
81 goes into 561 6 times with a remainder of 75.
Put 6 as the next digit of the answer. 
Result so far: 66.0
If we subtract 486 from 561, we get 75.
Bring next digit (6) of the dividend behind the 75 and repeat the process: 756 / 81

Let's proceed to step 5:
81 can be fit into 756 9 times, resulting in a remainder of 27.
The next digit of our result is 9. 
Result so far: 669.0
The remainder is 27 after subtracting 729 from 756.
Append the next digit (8) from the dividend to 27 and continue with: 278 / 81

Step 6:
81 can be fit into 278 3 times, resulting in a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 6693.0
Deduct 243 from 278 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 7:
If we divide 350 by 81, we get 4 and a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 6693.4
If we take 324 away from 350, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 8:
When dividing 260 by 81, we get 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 6693.43
If we subtract 243 from 260, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 9:
If we divide 170 by 81, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 6693.432
Subtract 162 from 170 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
81 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 6693.432
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 11:
800 divided by 81 is 9 with a remainder of 71.
The next digit of our result is 9. 
Result so far: 6693.43209
If we subtract 729 from 800, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 12:
The number 81 fits into 710 8 times, leaving a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 6693.432098
Subtracting 648 from 710 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 13:
81 goes into 620 7 times with a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 6693.4320987
If we take 567 away from 620, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 14:
530 divided by 81 is 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 6693.43209876
Subtract 486 from 530 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 6693.43209876 and a remainder of 4.4e-08.
