98310603 ÷ 804 
Let's see how many times 804 fits into 98310603.

Going ahead to step 1:
804 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 804

Moving on to step 2:
804 can be fit into 98 0 times, resulting in a remainder of 98.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Fetch the next digit (3) from the dividend, attach it to 98 and continue: 983 / 804

Moving on to step 3:
If we divide 983 by 804, we get 1 and a remainder of 179.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 804 from 983 to get 179.
Take the next digit (1) from the dividend and append it to 179, then repeat: 1791 / 804

Let's proceed to step 4:
When dividing 1791 by 804, we get 2 with a remainder of 183.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 1608 away from 1791, we end up with 183.
Include the next digit (0) from the dividend after 183, then repeat: 1830 / 804

Moving on to step 5:
The number 804 fits into 1830 2 times, leaving a remainder of 222.
Write down 2 as next digit of the result. 
Result so far: 122.0
Subtracting 1608 from 1830 leaves us with 222.
Append the next digit (6) from the dividend to 222 and continue with: 2226 / 804

Moving on to step 6:
When dividing 2226 by 804, we get 2 with a remainder of 618.
Put 2 as the next digit of the answer. 
Result so far: 1222.0
If we subtract 1608 from 2226, we get 618.
Append the next digit (0) from the dividend to 618 and continue with: 6180 / 804

Step 7:
If we divide 6180 by 804, we get 7 and a remainder of 552.
Put 7 as the next digit of the answer. 
Result so far: 12227.0
Deduct 5628 from 6180 and we're left with 552.
Append the next digit (3) from the dividend to 552 and continue with: 5523 / 804

On to step 8:
804 goes into 5523 6 times with a remainder of 699.
Put 6 as the next digit of the answer. 
Result so far: 122276.0
Subtracting 4824 from 5523 leaves us with 699.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6990, and continue the process.

Let's proceed to step 9:
If we divide 6990 by 804, we get 8 and a remainder of 558.
Write down 8 as next digit of the result. 
Result so far: 122276.8
If we subtract 6432 from 6990, we get 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Advancing to step 10:
When dividing 5580 by 804, we get 6 with a remainder of 756.
Use 6 as the next digit of our solution. 
Result so far: 122276.86
If we take 4824 away from 5580, we end up with 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

Step 11:
If we divide 7560 by 804, we get 9 and a remainder of 324.
The next digit of our result is 9. 
Result so far: 122276.869
Subtract 7236 from 7560 to get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Advancing to step 12:
The number 804 fits into 3240 4 times, leaving a remainder of 24.
The next digit of our result is 4. 
Result so far: 122276.8694
If we subtract 3216 from 3240, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 13:
When dividing 240 by 804, we get 0 with a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 122276.8694
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 14:
804 can be fit into 2400 2 times, resulting in a remainder of 792.
Record the quotient 2 as the next digit in the result. 
Result so far: 122276.869402
Deduct 1608 from 2400 and we're left with 792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Moving on to step 15:
When dividing 7920 by 804, we get 9 with a remainder of 684.
The number 9 becomes the next digit in our result. 
Result so far: 122276.8694029
The remainder is 684 after subtracting 7236 from 7920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Advancing to step 16:
804 goes into 6840 8 times with a remainder of 408.
Record the quotient 8 as the next digit in the result. 
Result so far: 122276.86940298
Deduct 6432 from 6840 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

The final result is 122276.86940298 with a remainder of 4.08e-07.
