72689 divided by 81 
Let's see how many times 81 fits into 72689.

Going ahead to step 1:
When dividing 7 by 81, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 81

Moving on to step 2:
The number 81 fits into 72 0 times, leaving a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Append the next digit (6) from the dividend to 72 and continue with: 726 / 81

Step 3:
726 divided by 81 is 8 with a remainder of 78.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 648 from 726, we get 78.
Include the next digit (8) from the dividend after 78, then repeat: 788 / 81

Step 4:
81 goes into 788 9 times with a remainder of 59.
Use 9 as the next digit of our solution. 
Result so far: 89.0
If we subtract 729 from 788, we get 59.
Grab the next digit (9) from the dividend, add it to 59, then carry on: 599 / 81

On to step 5:
If we divide 599 by 81, we get 7 and a remainder of 32.
The next digit of our result is 7. 
Result so far: 897.0
The remainder is 32 after subtracting 567 from 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 6:
81 goes into 320 3 times with a remainder of 77.
Put 3 as the next digit of the answer. 
Result so far: 897.3
If we take 243 away from 320, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 7:
If we divide 770 by 81, we get 9 and a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 897.39
Subtract 729 from 770 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 8:
When dividing 410 by 81, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 897.395
Deduct 405 from 410 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
81 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 897.395
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
The number 81 fits into 500 6 times, leaving a remainder of 14.
The next digit of our result is 6. 
Result so far: 897.39506
If we take 486 away from 500, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
81 goes into 140 1 times with a remainder of 59.
The next digit of our result is 1. 
Result so far: 897.395061
The remainder is 59 after subtracting 81 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 12:
81 goes into 590 7 times with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 897.3950617
Deduct 567 from 590 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 13:
81 goes into 230 2 times with a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 897.39506172
The remainder is 68 after subtracting 162 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Our division results in 897.39506172 with a remaining 6.8e-08.
