23843855 ÷ 816 
Let's see how many times 816 fits into 23843855.

Advancing to step 1:
If we divide 2 by 816, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 816

Advancing to step 2:
816 can be fit into 23 0 times, resulting in a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Bring next digit (8) of the dividend behind the 23 and repeat the process: 238 / 816

Going ahead to step 3:
The number 816 fits into 238 0 times, leaving a remainder of 238.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 238 to get 238.
Fetch the next digit (4) from the dividend, attach it to 238 and continue: 2384 / 816

Moving on to step 4:
816 goes into 2384 2 times with a remainder of 752.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 752 after subtracting 1632 from 2384.
Fetch the next digit (3) from the dividend, attach it to 752 and continue: 7523 / 816

On to step 5:
The number 816 fits into 7523 9 times, leaving a remainder of 179.
The next digit of our result is 9. 
Result so far: 29.0
Subtracting 7344 from 7523 leaves us with 179.
Take the next digit (8) from the dividend and append it to 179, then repeat: 1798 / 816

Moving on to step 6:
When dividing 1798 by 816, we get 2 with a remainder of 166.
The next digit of our result is 2. 
Result so far: 292.0
Subtracting 1632 from 1798 leaves us with 166.
Fetch the next digit (5) from the dividend, attach it to 166 and continue: 1665 / 816

On to step 7:
When dividing 1665 by 816, we get 2 with a remainder of 33.
The next digit of our result is 2. 
Result so far: 2922.0
Subtracting 1632 from 1665 leaves us with 33.
Append the next digit (5) from the dividend to 33 and continue with: 335 / 816

Advancing to step 8:
If we divide 335 by 816, we get 0 and a remainder of 335.
Put 0 as the next digit of the answer. 
Result so far: 29220.0
If we subtract 0 from 335, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Going ahead to step 9:
816 can be fit into 3350 4 times, resulting in a remainder of 86.
Write down 4 as next digit of the result. 
Result so far: 29220.4
If we subtract 3264 from 3350, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 10:
860 divided by 816 is 1 with a remainder of 44.
The next digit of our result is 1. 
Result so far: 29220.41
Deduct 816 from 860 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.

Advancing to step 11:
816 goes into 440 0 times with a remainder of 440.
Use 0 as the next digit of our solution. 
Result so far: 29220.41
If we subtract 0 from 440, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 12:
816 can be fit into 4400 5 times, resulting in a remainder of 320.
The number 5 becomes the next digit in our result. 
Result so far: 29220.4105
The remainder is 320 after subtracting 4080 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 13:
When dividing 3200 by 816, we get 3 with a remainder of 752.
Record the quotient 3 as the next digit in the result. 
Result so far: 29220.41053
If we subtract 2448 from 3200, we get 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Advancing to step 14:
816 can be fit into 7520 9 times, resulting in a remainder of 176.
Put 9 as the next digit of the answer. 
Result so far: 29220.410539
Deduct 7344 from 7520 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 15:
If we divide 1760 by 816, we get 2 and a remainder of 128.
Write down 2 as next digit of the result. 
Result so far: 29220.4105392
Deduct 1632 from 1760 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 16:
816 goes into 1280 1 times with a remainder of 464.
The number 1 becomes the next digit in our result. 
Result so far: 29220.41053921
If we take 816 away from 1280, we end up with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

The final result is 29220.41053921 with a remainder of 4.64e-07.
