We divide 86804 by 81
We're looking to find how many times 81 goes into 86804.

Step 1:
When dividing 8 by 81, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 81

Step 2:
81 can be fit into 86 1 times, resulting in a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 81 from 86 to get 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 81

Advancing to step 3:
The number 81 fits into 58 0 times, leaving a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 58 after subtracting 0 from 58.
Fetch the next digit (0) from the dividend, attach it to 58 and continue: 580 / 81

Let's proceed to step 4:
When dividing 580 by 81, we get 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
Subtracting 567 from 580 leaves us with 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 81

Going ahead to step 5:
The number 81 fits into 134 1 times, leaving a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 1071.0
Subtracting 81 from 134 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 6:
81 can be fit into 530 6 times, resulting in a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 1071.6
Deduct 486 from 530 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 7:
81 goes into 440 5 times with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 1071.65
Subtract 405 from 440 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 8:
The number 81 fits into 350 4 times, leaving a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 1071.654
If we take 324 away from 350, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 9:
The number 81 fits into 260 3 times, leaving a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 1071.6543
Subtract 243 from 260 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 10:
When dividing 170 by 81, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 1071.65432
If we take 162 away from 170, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
81 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 1071.65432
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 12:
The number 81 fits into 800 9 times, leaving a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 1071.6543209
Subtracting 729 from 800 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 13:
The number 81 fits into 710 8 times, leaving a remainder of 62.
The next digit of our result is 8. 
Result so far: 1071.65432098
If we take 648 away from 710, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

After the division, we end up with 1071.65432098 and a remainder of 6.2e-08.
