854002 divided by 81 
Let's see how many times 81 fits into 854002.

Going ahead to step 1:
81 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 81

Let's proceed to step 2:
The number 81 fits into 85 1 times, leaving a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 4 after subtracting 81 from 85.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 81

Going ahead to step 3:
The number 81 fits into 44 0 times, leaving a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 44, we end up with 44.
Bring next digit (0) of the dividend behind the 44 and repeat the process: 440 / 81

Going ahead to step 4:
81 goes into 440 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
Subtracting 405 from 440 leaves us with 35.
Include the next digit (0) from the dividend after 35, then repeat: 350 / 81

Going ahead to step 5:
When dividing 350 by 81, we get 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 1054.0
Subtract 324 from 350 to get 26.
Include the next digit (2) from the dividend after 26, then repeat: 262 / 81

Advancing to step 6:
The number 81 fits into 262 3 times, leaving a remainder of 19.
The next digit of our result is 3. 
Result so far: 10543.0
If we subtract 243 from 262, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
81 goes into 190 2 times with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 10543.2
If we subtract 162 from 190, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 8:
81 can be fit into 280 3 times, resulting in a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 10543.23
If we subtract 243 from 280, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 9:
The number 81 fits into 370 4 times, leaving a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 10543.234
Deduct 324 from 370 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 10:
460 divided by 81 is 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 10543.2345
Deduct 405 from 460 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 11:
81 goes into 550 6 times with a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 10543.23456
Subtract 486 from 550 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 12:
The number 81 fits into 640 7 times, leaving a remainder of 73.
Put 7 as the next digit of the answer. 
Result so far: 10543.234567
The remainder is 73 after subtracting 567 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 13:
81 goes into 730 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 10543.2345679
Subtracting 729 from 730 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 14:
81 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 10543.2345679
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 10543.2345679 and a remainder of 1e-08.
