We're dividing 71718182 by 81 
We want to figure out the number of times 71718182 can be divided by 81.

Moving on to step 1:
81 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 81

Moving on to step 2:
The number 81 fits into 71 0 times, leaving a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Append the next digit (7) from the dividend to 71 and continue with: 717 / 81

Advancing to step 3:
When dividing 717 by 81, we get 8 with a remainder of 69.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 648 from 717 leaves us with 69.
Grab the next digit (1) from the dividend, add it to 69, then carry on: 691 / 81

Going ahead to step 4:
81 can be fit into 691 8 times, resulting in a remainder of 43.
The next digit of our result is 8. 
Result so far: 88.0
Deduct 648 from 691 and we're left with 43.
Include the next digit (8) from the dividend after 43, then repeat: 438 / 81

Going ahead to step 5:
The number 81 fits into 438 5 times, leaving a remainder of 33.
The number 5 becomes the next digit in our result. 
Result so far: 885.0
Subtracting 405 from 438 leaves us with 33.
Grab the next digit (1) from the dividend, add it to 33, then carry on: 331 / 81

Moving on to step 6:
81 can be fit into 331 4 times, resulting in a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 8854.0
If we take 324 away from 331, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 81

Let's proceed to step 7:
81 goes into 78 0 times with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 88540.0
If we take 0 away from 78, we end up with 78.
Append the next digit (2) from the dividend to 78 and continue with: 782 / 81

Let's proceed to step 8:
81 goes into 782 9 times with a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 885409.0
Subtract 729 from 782 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 9:
81 can be fit into 530 6 times, resulting in a remainder of 44.
The next digit of our result is 6. 
Result so far: 885409.6
The remainder is 44 after subtracting 486 from 530.
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 10:
When dividing 440 by 81, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 885409.65
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.

Going ahead to step 11:
If we divide 350 by 81, we get 4 and a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 885409.654
Subtracting 324 from 350 leaves us 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.

Step 12:
81 can be fit into 260 3 times, resulting in a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 885409.6543
If we subtract 243 from 260, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 13:
When dividing 170 by 81, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 885409.65432
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.

On to step 14:
The number 81 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 885409.65432
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 15:
81 can be fit into 800 9 times, resulting in a remainder of 71.
The next digit of our result is 9. 
Result so far: 885409.6543209
The remainder is 71 after subtracting 729 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 16:
The number 81 fits into 710 8 times, leaving a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 885409.65432098
Subtracting 648 from 710 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The quotient of the division is 885409.65432098, and the remainder is 6.2e-08.
