Let's divide 718931 by 81
We want to figure out the number of times 718931 can be divided by 81.

Moving on to step 1:
When dividing 7 by 81, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 81

Going ahead to step 2:
81 goes into 71 0 times with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Append the next digit (8) from the dividend to 71 and continue with: 718 / 81

Moving on to step 3:
81 can be fit into 718 8 times, resulting in a remainder of 70.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 648 from 718 to get 70.
Include the next digit (9) from the dividend after 70, then repeat: 709 / 81

Going ahead to step 4:
81 goes into 709 8 times with a remainder of 61.
The next digit of our result is 8. 
Result so far: 88.0
The remainder is 61 after subtracting 648 from 709.
Take the next digit (3) from the dividend and append it to 61, then repeat: 613 / 81

On to step 5:
If we divide 613 by 81, we get 7 and a remainder of 46.
Write down 7 as next digit of the result. 
Result so far: 887.0
If we take 567 away from 613, we end up with 46.
Grab the next digit (1) from the dividend, add it to 46, then carry on: 461 / 81

Let's proceed to step 6:
81 can be fit into 461 5 times, resulting in a remainder of 56.
Record the quotient 5 as the next digit in the result. 
Result so far: 8875.0
Subtracting 405 from 461 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 7:
560 divided by 81 is 6 with a remainder of 74.
Record the quotient 6 as the next digit in the result. 
Result so far: 8875.6
If we take 486 away from 560, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 8:
740 divided by 81 is 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 8875.69
Subtract 729 from 740 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
81 can be fit into 110 1 times, resulting in a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 8875.691
Subtracting 81 from 110 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 10:
81 goes into 290 3 times with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 8875.6913
Subtracting 243 from 290 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 11:
81 goes into 470 5 times with a remainder of 65.
The next digit of our result is 5. 
Result so far: 8875.69135
Subtract 405 from 470 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 12:
The number 81 fits into 650 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 8875.691358
Subtract 648 from 650 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
If we divide 20 by 81, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 8875.691358
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
When dividing 200 by 81, we get 2 with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 8875.69135802
If we take 162 away from 200, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 8875.69135802 with a remainder of 3.8e-08.
