387721 ÷ 23 
Let's see how many times 23 fits into 387721.

On to step 1:
When dividing 3 by 23, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 23

Going ahead to step 2:
38 divided by 23 is 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 15 after subtracting 23 from 38.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 23

Advancing to step 3:
The number 23 fits into 157 6 times, leaving a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 138 away from 157, we end up with 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 23

Let's proceed to step 4:
The number 23 fits into 197 8 times, leaving a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 168.0
Deduct 184 from 197 and we're left with 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 23

Going ahead to step 5:
132 divided by 23 is 5 with a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 1685.0
If we subtract 115 from 132, we get 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 23

Step 6:
When dividing 171 by 23, we get 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 16857.0
If we take 161 away from 171, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
23 goes into 100 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 16857.4
The remainder is 8 after subtracting 92 from 100.
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 8:
When dividing 80 by 23, we get 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 16857.43
Subtract 69 from 80 to 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.

Going ahead to step 9:
23 goes into 110 4 times with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 16857.434
Deduct 92 from 110 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
23 goes into 180 7 times with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 16857.4347
If we subtract 161 from 180, we 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.

Let's proceed to step 11:
If we divide 190 by 23, we get 8 and a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 16857.43478
If we take 184 away from 190, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
If we divide 60 by 23, we get 2 and a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 16857.434782
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.

Moving on to step 13:
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: 16857.4347826
The remainder is 2 after subtracting 138 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
23 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 16857.4347826
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 16857.4347826 with a remainder of 2e-08.
