858235 ÷ 81 
Our goal is to divide 858235 by 81.

On to step 1:
When dividing 8 by 81, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 81

Step 2:
If we divide 85 by 81, we get 1 and a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
If we take 81 away from 85, we end up with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 81

Going ahead to step 3:
The number 81 fits into 48 0 times, leaving a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 48 leaves us with 48.
Include the next digit (2) from the dividend after 48, then repeat: 482 / 81

Step 4:
482 divided by 81 is 5 with a remainder of 77.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
Subtracting 405 from 482 leaves us with 77.
Bring next digit (3) of the dividend behind the 77 and repeat the process: 773 / 81

Step 5:
81 goes into 773 9 times with a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 1059.0
Subtract 729 from 773 to get 44.
Bring next digit (5) of the dividend behind the 44 and repeat the process: 445 / 81

Step 6:
If we divide 445 by 81, we get 5 and a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 10595.0
Deduct 405 from 445 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
81 goes into 400 4 times with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 10595.4
Deduct 324 from 400 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 8:
If we divide 760 by 81, we get 9 and a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 10595.49
Subtracting 729 from 760 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 9:
310 divided by 81 is 3 with a remainder of 67.
The next digit of our result is 3. 
Result so far: 10595.493
Subtracting 243 from 310 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 10:
The number 81 fits into 670 8 times, leaving a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 10595.4938
The remainder is 22 after subtracting 648 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
When dividing 220 by 81, we get 2 with a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 10595.49382
The remainder is 58 after subtracting 162 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 12:
When dividing 580 by 81, we get 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 10595.493827
Deduct 567 from 580 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 13:
130 divided by 81 is 1 with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 10595.4938271
If we subtract 81 from 130, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 14:
81 can be fit into 490 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 10595.49382716
The remainder is 4 after subtracting 486 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 10595.49382716 with a remainder of 4e-09.
