804023 ÷ 86 
Let's see how many times 86 fits into 804023.

Going ahead to step 1:
If we divide 8 by 86, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 86

Let's proceed to step 2:
86 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Grab the next digit (4) from the dividend, add it to 80, then carry on: 804 / 86

Step 3:
The number 86 fits into 804 9 times, leaving a remainder of 30.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 774 from 804 leaves us with 30.
Take the next digit (0) from the dividend and append it to 30, then repeat: 300 / 86

Step 4:
86 can be fit into 300 3 times, resulting in a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
The remainder is 42 after subtracting 258 from 300.
Bring next digit (2) of the dividend behind the 42 and repeat the process: 422 / 86

Step 5:
422 divided by 86 is 4 with a remainder of 78.
Write down 4 as next digit of the result. 
Result so far: 934.0
If we subtract 344 from 422, we get 78.
Bring next digit (3) of the dividend behind the 78 and repeat the process: 783 / 86

Advancing to step 6:
The number 86 fits into 783 9 times, leaving a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 9349.0
If we take 774 away from 783, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
The number 86 fits into 90 1 times, leaving a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 9349.1
Subtracting 86 from 90 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
86 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 9349.1
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
If we divide 400 by 86, we get 4 and a remainder of 56.
The next digit of our result is 4. 
Result so far: 9349.104
The remainder is 56 after subtracting 344 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 10:
When dividing 560 by 86, we get 6 with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 9349.1046
The remainder is 44 after subtracting 516 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 11:
440 divided by 86 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 9349.10465
Deduct 430 from 440 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
The number 86 fits into 100 1 times, leaving a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 9349.104651
The remainder is 14 after subtracting 86 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 13:
When dividing 140 by 86, we get 1 with a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 9349.1046511
If we subtract 86 from 140, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 9349.1046511 and a remainder of 5.4e-07.
