8308990 ÷ 804 
Our goal is to divide 8308990 by 804.

Step 1:
The number 804 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 804

Step 2:
804 goes into 83 0 times with a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Append the next digit (0) from the dividend to 83 and continue with: 830 / 804

Let's proceed to step 3:
If we divide 830 by 804, we get 1 and a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 26 after subtracting 804 from 830.
Include the next digit (8) from the dividend after 26, then repeat: 268 / 804

Moving on to step 4:
The number 804 fits into 268 0 times, leaving a remainder of 268.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 268, we get 268.
Fetch the next digit (9) from the dividend, attach it to 268 and continue: 2689 / 804

Advancing to step 5:
804 goes into 2689 3 times with a remainder of 277.
Write down 3 as next digit of the result. 
Result so far: 103.0
Deduct 2412 from 2689 and we're left with 277.
Include the next digit (9) from the dividend after 277, then repeat: 2779 / 804

Moving on to step 6:
2779 divided by 804 is 3 with a remainder of 367.
Put 3 as the next digit of the answer. 
Result so far: 1033.0
If we take 2412 away from 2779, we end up with 367.
Include the next digit (0) from the dividend after 367, then repeat: 3670 / 804

Let's proceed to step 7:
3670 divided by 804 is 4 with a remainder of 454.
Use 4 as the next digit of our solution. 
Result so far: 10334.0
If we subtract 3216 from 3670, we get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

On to step 8:
When dividing 4540 by 804, we get 5 with a remainder of 520.
The next digit of our result is 5. 
Result so far: 10334.5
Subtracting 4020 from 4540 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 9:
The number 804 fits into 5200 6 times, leaving a remainder of 376.
The number 6 becomes the next digit in our result. 
Result so far: 10334.56
Subtracting 4824 from 5200 leaves us with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Advancing to step 10:
804 can be fit into 3760 4 times, resulting in a remainder of 544.
Put 4 as the next digit of the answer. 
Result so far: 10334.564
If we take 3216 away from 3760, we end up with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Let's proceed to step 11:
5440 divided by 804 is 6 with a remainder of 616.
The next digit of our result is 6. 
Result so far: 10334.5646
Subtracting 4824 from 5440 leaves us with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

On to step 12:
If we divide 6160 by 804, we get 7 and a remainder of 532.
Put 7 as the next digit of the answer. 
Result so far: 10334.56467
Subtracting 5628 from 6160 leaves us with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Step 13:
5320 divided by 804 is 6 with a remainder of 496.
Use 6 as the next digit of our solution. 
Result so far: 10334.564676
If we subtract 4824 from 5320, we get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Moving on to step 14:
If we divide 4960 by 804, we get 6 and a remainder of 136.
Write down 6 as next digit of the result. 
Result so far: 10334.5646766
Subtracting 4824 from 4960 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Our division results in 10334.5646766 with a remaining 1.36e-06.
