19308240 ÷ 823 
Let's see how many times 823 fits into 19308240.

On to step 1:
823 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 823

Advancing to step 2:
19 divided by 823 is 0 with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Bring next digit (3) of the dividend behind the 19 and repeat the process: 193 / 823

Going ahead to step 3:
The number 823 fits into 193 0 times, leaving a remainder of 193.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 193 and we're left with 193.
Include the next digit (0) from the dividend after 193, then repeat: 1930 / 823

Moving on to step 4:
The number 823 fits into 1930 2 times, leaving a remainder of 284.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 1646 from 1930 leaves us with 284.
Include the next digit (8) from the dividend after 284, then repeat: 2848 / 823

On to step 5:
2848 divided by 823 is 3 with a remainder of 379.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Subtract 2469 from 2848 to get 379.
Take the next digit (2) from the dividend and append it to 379, then repeat: 3792 / 823

On to step 6:
3792 divided by 823 is 4 with a remainder of 500.
Record the quotient 4 as the next digit in the result. 
Result so far: 234.0
If we take 3292 away from 3792, we end up with 500.
Bring next digit (4) of the dividend behind the 500 and repeat the process: 5004 / 823

Let's proceed to step 7:
The number 823 fits into 5004 6 times, leaving a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 2346.0
If we take 4938 away from 5004, we end up with 66.
Grab the next digit (0) from the dividend, add it to 66, then carry on: 660 / 823

Let's proceed to step 8:
823 goes into 660 0 times with a remainder of 660.
Put 0 as the next digit of the answer. 
Result so far: 23460.0
Subtracting 0 from 660 leaves us with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Step 9:
823 can be fit into 6600 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 23460.8
Subtract 6584 from 6600 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
823 can be fit into 160 0 times, resulting in a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 23460.8
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 11:
1600 divided by 823 is 1 with a remainder of 777.
The number 1 becomes the next digit in our result. 
Result so far: 23460.801
If we subtract 823 from 1600, we get 777.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7770, and continue the process.

Going ahead to step 12:
When dividing 7770 by 823, we get 9 with a remainder of 363.
The number 9 becomes the next digit in our result. 
Result so far: 23460.8019
Subtracting 7407 from 7770 leaves us with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Step 13:
When dividing 3630 by 823, we get 4 with a remainder of 338.
Use 4 as the next digit of our solution. 
Result so far: 23460.80194
If we take 3292 away from 3630, we end up with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Going ahead to step 14:
823 goes into 3380 4 times with a remainder of 88.
Use 4 as the next digit of our solution. 
Result so far: 23460.801944
Subtract 3292 from 3380 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The final result is 23460.801944 with a remainder of 8.8e-06.
