We look at the division of 388409 by 23 
Let's see how many times 23 fits into 388409.

On to step 1:
When dividing 3 by 23, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 23

Advancing to step 2:
The number 23 fits into 38 1 times, leaving a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 23 away from 38, we end up with 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 23

Let's proceed to step 3:
158 divided by 23 is 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 138 from 158 and we're left with 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 23

Moving on to step 4:
If we divide 204 by 23, we get 8 and a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 168.0
The remainder is 20 after subtracting 184 from 204.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 23

Going ahead to step 5:
23 goes into 200 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 1688.0
If we take 184 away from 200, we end up with 16.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 23

Moving on to step 6:
The number 23 fits into 169 7 times, leaving a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 16887.0
If we subtract 161 from 169, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
If we divide 80 by 23, we get 3 and a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 16887.3
If we subtract 69 from 80, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 8:
If we divide 110 by 23, we get 4 and a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 16887.34
If we subtract 92 from 110, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
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: 16887.347
The remainder is 19 after subtracting 161 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 10:
190 divided by 23 is 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 16887.3478
If we subtract 184 from 190, we 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.

Step 11:
The number 23 fits into 60 2 times, leaving a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 16887.34782
If we take 46 away from 60, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 12:
If we divide 140 by 23, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 16887.347826
Subtract 138 from 140 to 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.

On to step 13:
23 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 16887.347826
Subtract 0 from 20 to get 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 14:
If we divide 200 by 23, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 16887.34782608
The remainder is 16 after subtracting 184 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 16887.34782608 with a remainder of 1.6e-08.
