We look at the division of 718139 by 81 
We want to divide 718139 by 81.

Step 1:
If we divide 7 by 81, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 81

On to step 2:
71 divided by 81 is 0 with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Bring next digit (8) of the dividend behind the 71 and repeat the process: 718 / 81

Going ahead to step 3:
The number 81 fits into 718 8 times, leaving a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 70 after subtracting 648 from 718.
Grab the next digit (1) from the dividend, add it to 70, then carry on: 701 / 81

Step 4:
If we divide 701 by 81, we get 8 and a remainder of 53.
Use 8 as the next digit of our solution. 
Result so far: 88.0
The remainder is 53 after subtracting 648 from 701.
Append the next digit (3) from the dividend to 53 and continue with: 533 / 81

Going ahead to step 5:
If we divide 533 by 81, we get 6 and a remainder of 47.
Write down 6 as next digit of the result. 
Result so far: 886.0
Deduct 486 from 533 and we're left with 47.
Append the next digit (9) from the dividend to 47 and continue with: 479 / 81

Let's proceed to step 6:
81 can be fit into 479 5 times, resulting in a remainder of 74.
Record the quotient 5 as the next digit in the result. 
Result so far: 8865.0
Deduct 405 from 479 and we're left 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.

Step 7:
If we divide 740 by 81, we get 9 and a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 8865.9
If we subtract 729 from 740, we 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 8:
If we divide 110 by 81, we get 1 and a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 8865.91
If we take 81 away from 110, we end up 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.

Step 9:
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: 8865.913
If we take 243 away from 290, we end up 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.

On to step 10:
If we divide 470 by 81, we get 5 and a remainder of 65.
The next digit of our result is 5. 
Result so far: 8865.9135
The remainder is 65 after subtracting 405 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 11:
If we divide 650 by 81, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 8865.91358
If we subtract 648 from 650, we 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.

Advancing to step 12:
81 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 8865.91358
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
When dividing 200 by 81, we get 2 with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 8865.9135802
Deduct 162 from 200 and we're left 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.

On to step 14:
The number 81 fits into 380 4 times, leaving a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 8865.91358024
Deduct 324 from 380 and we're left 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.

After the division, we end up with 8865.91358024 and a remainder of 5.6e-08.
