Let's divide 863780 by 81
We want to figure out the number of times 863780 can be divided by 81.

Going ahead to step 1:
81 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 81

Let's proceed to step 2:
81 goes into 86 1 times with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 81 from 86 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 81

Going ahead to step 3:
If we divide 53 by 81, we get 0 and a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 53 leaves us with 53.
Take the next digit (7) from the dividend and append it to 53, then repeat: 537 / 81

Advancing to step 4:
If we divide 537 by 81, we get 6 and a remainder of 51.
Record the quotient 6 as the next digit in the result. 
Result so far: 106.0
If we take 486 away from 537, we end up with 51.
Append the next digit (8) from the dividend to 51 and continue with: 518 / 81

Step 5:
When dividing 518 by 81, we get 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 1066.0
Subtracting 486 from 518 leaves us with 32.
Take the next digit (0) from the dividend and append it to 32, then repeat: 320 / 81

Step 6:
81 goes into 320 3 times with a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 10663.0
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.

Going ahead to step 7:
81 goes into 770 9 times with a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 10663.9
Deduct 729 from 770 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to 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: 10663.95
If we take 405 away from 410, we end up 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.

Moving on to step 9:
81 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 10663.95
Subtract 0 from 50 to 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.

Let's proceed to step 10:
When dividing 500 by 81, we get 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 10663.9506
If we subtract 486 from 500, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 11:
If we divide 140 by 81, we get 1 and a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 10663.95061
If we subtract 81 from 140, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 12:
The number 81 fits into 590 7 times, leaving a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 10663.950617
If we take 567 away from 590, we end up 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:
If we divide 230 by 81, we get 2 and a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 10663.9506172
Subtracting 162 from 230 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 14:
680 divided by 81 is 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 10663.95061728
If we take 648 away from 680, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 10663.95061728 with a remaining 3.2e-08.
