171556 divided by 81 
We want to figure out the number of times 171556 can be divided by 81.

Let's proceed to step 1:
81 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 81

Let's proceed to step 2:
If we divide 17 by 81, we get 0 and a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 81

Step 3:
The number 81 fits into 171 2 times, leaving a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 162 from 171 to get 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 81

Moving on to step 4:
The number 81 fits into 95 1 times, leaving a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtract 81 from 95 to get 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 81

Let's proceed to step 5:
When dividing 145 by 81, we get 1 with a remainder of 64.
Use 1 as the next digit of our solution. 
Result so far: 211.0
Deduct 81 from 145 and we're left with 64.
Take the next digit (6) from the dividend and append it to 64, then repeat: 646 / 81

Moving on to step 6:
If we divide 646 by 81, we get 7 and a remainder of 79.
The next digit of our result is 7. 
Result so far: 2117.0
Deduct 567 from 646 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 7:
The number 81 fits into 790 9 times, leaving a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 2117.9
Subtract 729 from 790 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 8:
If we divide 610 by 81, we get 7 and a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 2117.97
Deduct 567 from 610 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 9:
The number 81 fits into 430 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 2117.975
The remainder is 25 after subtracting 405 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
250 divided by 81 is 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 2117.9753
Subtract 243 from 250 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 11:
70 divided by 81 is 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 2117.9753
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 12:
When dividing 700 by 81, we get 8 with a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 2117.975308
The remainder is 52 after subtracting 648 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 13:
When dividing 520 by 81, we get 6 with a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 2117.9753086
The remainder is 34 after subtracting 486 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 14:
81 goes into 340 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 2117.97530864
Subtract 324 from 340 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 2117.97530864 with a balance of 1.6e-08.
