On to step 4:
547 divided by 81 is 6 with a remainder of 61.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 486 away from 547, we end up with 61.
Take the next digit (2) from the dividend and append it to 61, then repeat: 612 / 81

Let's proceed to step 5:
81 can be fit into 612 7 times, resulting in a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 167.0
The remainder is 45 after subtracting 567 from 612.
Append the next digit (1) from the dividend to 45 and continue with: 451 / 81

Step 6:
451 divided by 81 is 5 with a remainder of 46.
The number 5 becomes the next digit in our result. 
Result so far: 1675.0
If we take 405 away from 451, we end up with 46.
Grab the next digit (9) from the dividend, add it to 46, then carry on: 469 / 81

On to step 7:
If we divide 469 by 81, we get 5 and a remainder of 64.
Record the quotient 5 as the next digit in the result. 
Result so far: 16755.0
The remainder is 64 after subtracting 405 from 469.
Fetch the next digit (4) from the dividend, attach it to 64 and continue: 644 / 81

Going ahead to step 8:
If we divide 644 by 81, we get 7 and a remainder of 77.
The next digit of our result is 7. 
Result so far: 167557.0
The remainder is 77 after subtracting 567 from 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 9:
81 goes into 770 9 times with a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 167557.9
Subtracting 729 from 770 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 10:
When dividing 410 by 81, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 167557.95
Subtracting 405 from 410 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
If we divide 50 by 81, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 167557.95
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
500 divided by 81 is 6 with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 167557.9506
Subtracting 486 from 500 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 13:
81 goes into 140 1 times with a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 167557.95061
Subtracting 81 from 140 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 14:
81 goes into 590 7 times with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 167557.950617
If we take 567 away from 590, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 15:
81 goes into 230 2 times with a remainder of 68.
The next digit of our result is 2. 
Result so far: 167557.9506172
If we subtract 162 from 230, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 16:
680 divided by 81 is 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 167557.95061728
If we take 648 away from 680, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 167557.95061728 with a remainder of 3.2e-08.
