400816 divided by 23 
We want to divide 400816 by 23.

Moving on to step 1:
When dividing 4 by 23, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 23

Step 2:
40 divided by 23 is 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 23 from 40 and we're left with 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 23

Step 3:
23 goes into 170 7 times with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Deduct 161 from 170 and we're left with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 23

Moving on to step 4:
23 goes into 98 4 times with a remainder of 6.
The next digit of our result is 4. 
Result so far: 174.0
The remainder is 6 after subtracting 92 from 98.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 23

On to step 5:
23 goes into 61 2 times with a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 1742.0
Subtracting 46 from 61 leaves us with 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 23

Let's proceed to step 6:
The number 23 fits into 156 6 times, leaving a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 17426.0
The remainder is 18 after subtracting 138 from 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
If we divide 180 by 23, we get 7 and a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 17426.7
Subtract 161 from 180 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 8:
If we divide 190 by 23, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 17426.78
Subtract 184 from 190 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
23 goes into 60 2 times with a remainder of 14.
The next digit of our result is 2. 
Result so far: 17426.782
Subtract 46 from 60 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
When dividing 140 by 23, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 17426.7826
If we subtract 138 from 140, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
23 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 17426.7826
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
When dividing 200 by 23, we get 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 17426.782608
If we subtract 184 from 200, we 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 13:
23 can be fit into 160 6 times, resulting in a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 17426.7826086
Subtracting 138 from 160 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 14:
220 divided by 23 is 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 17426.78260869
Subtracting 207 from 220 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 17426.78260869 and a remainder of 1.3e-08.
