We divide 171197 by 81
We want to figure out the number of times 171197 can be divided by 81.

Advancing to step 1:
If we divide 1 by 81, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 81

Advancing to step 2:
The number 81 fits into 17 0 times, leaving a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 81

Going ahead to step 3:
81 goes into 171 2 times with a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 162 from 171, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 81

Going ahead to step 4:
91 divided by 81 is 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
The remainder is 10 after subtracting 81 from 91.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 81

Moving on to step 5:
81 can be fit into 109 1 times, resulting in a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 211.0
If we take 81 away from 109, we end up with 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 81

Advancing to step 6:
81 can be fit into 287 3 times, resulting in a remainder of 44.
The next digit of our result is 3. 
Result so far: 2113.0
Deduct 243 from 287 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 7:
440 divided by 81 is 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 2113.5
If we take 405 away from 440, we end up 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.

Moving on to step 8:
350 divided by 81 is 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 2113.54
Deduct 324 from 350 and we're left 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.

Advancing to step 9:
The number 81 fits into 260 3 times, leaving a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 2113.543
The remainder is 17 after subtracting 243 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 10:
81 goes into 170 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 2113.5432
The remainder is 8 after subtracting 162 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
When dividing 80 by 81, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 2113.5432
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.

Moving on to step 12:
When dividing 800 by 81, we get 9 with a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 2113.543209
If we take 729 away from 800, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 13:
81 can be fit into 710 8 times, resulting in a remainder of 62.
The next digit of our result is 8. 
Result so far: 2113.5432098
If we subtract 648 from 710, we get 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 14:
81 can be fit into 620 7 times, resulting in a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 2113.54320987
Deduct 567 from 620 and we're left 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.

The final result is 2113.54320987 with a remainder of 5.3e-08.
