542054 ÷ 81 
We want to divide 542054 by 81.

On to step 1:
81 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 81

On to step 2:
81 goes into 54 0 times with a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Append the next digit (2) from the dividend to 54 and continue with: 542 / 81

Moving on to step 3:
The number 81 fits into 542 6 times, leaving a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 486 from 542, we get 56.
Append the next digit (0) from the dividend to 56 and continue with: 560 / 81

Moving on to step 4:
81 can be fit into 560 6 times, resulting in a remainder of 74.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
If we take 486 away from 560, we end up with 74.
Grab the next digit (5) from the dividend, add it to 74, then carry on: 745 / 81

Going ahead to step 5:
The number 81 fits into 745 9 times, leaving a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 669.0
Subtracting 729 from 745 leaves us with 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 81

Advancing to step 6:
If we divide 164 by 81, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 6692.0
Subtract 162 from 164 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.

Step 7:
When dividing 20 by 81, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 6692.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
81 can be fit into 200 2 times, resulting in a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 6692.02
If we subtract 162 from 200, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 9:
380 divided by 81 is 4 with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 6692.024
Subtracting 324 from 380 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 10:
81 goes into 560 6 times with a remainder of 74.
Record the quotient 6 as the next digit in the result. 
Result so far: 6692.0246
The remainder is 74 after subtracting 486 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 11:
740 divided by 81 is 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 6692.02469
Deduct 729 from 740 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 12:
If we divide 110 by 81, we get 1 and a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 6692.024691
Subtracting 81 from 110 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 13:
290 divided by 81 is 3 with a remainder of 47.
The next digit of our result is 3. 
Result so far: 6692.0246913
Subtracting 243 from 290 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 14:
If we divide 470 by 81, we get 5 and a remainder of 65.
The next digit of our result is 5. 
Result so far: 6692.02469135
Deduct 405 from 470 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

After the division, we end up with 6692.02469135 and a remainder of 6.5e-08.
