We look at the division of 549408 by 81 
Our goal is to divide 549408 by 81.

Advancing to step 1:
If we divide 5 by 81, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 81

Let's proceed to step 2:
When dividing 54 by 81, we get 0 with a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Fetch the next digit (9) from the dividend, attach it to 54 and continue: 549 / 81

Let's proceed to step 3:
The number 81 fits into 549 6 times, leaving a remainder of 63.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 486 from 549, we get 63.
Include the next digit (4) from the dividend after 63, then repeat: 634 / 81

Going ahead to step 4:
81 goes into 634 7 times with a remainder of 67.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
Subtract 567 from 634 to get 67.
Take the next digit (0) from the dividend and append it to 67, then repeat: 670 / 81

Let's proceed to step 5:
81 can be fit into 670 8 times, resulting in a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 678.0
If we subtract 648 from 670, we get 22.
Take the next digit (8) from the dividend and append it to 22, then repeat: 228 / 81

Step 6:
When dividing 228 by 81, we get 2 with a remainder of 66.
Record the quotient 2 as the next digit in the result. 
Result so far: 6782.0
If we take 162 away from 228, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 7:
The number 81 fits into 660 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 6782.8
Deduct 648 from 660 and we're left 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.

Step 8:
81 can be fit into 120 1 times, resulting in a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 6782.81
Subtract 81 from 120 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 9:
81 can be fit into 390 4 times, resulting in a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 6782.814
Deduct 324 from 390 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 10:
81 can be fit into 660 8 times, resulting in a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 6782.8148
Subtracting 648 from 660 leaves us 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.

Moving on to step 11:
If we divide 120 by 81, we get 1 and a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 6782.81481
Deduct 81 from 120 and we're left 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.

Let's proceed to step 12:
When dividing 390 by 81, we get 4 with a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 6782.814814
Subtract 324 from 390 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 13:
When dividing 660 by 81, we get 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 6782.8148148
Deduct 648 from 660 and we're left 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.

On to step 14:
81 can be fit into 120 1 times, resulting in a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 6782.81481481
Subtracting 81 from 120 leaves us 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.

After the division, we end up with 6782.81481481 and a remainder of 3.9e-08.
