383851 ÷ 23 
Let's see how many times 23 fits into 383851.

Advancing to step 1:
23 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
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

Moving on to step 2:
38 divided by 23 is 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 23 away from 38, we end up with 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 23

Moving on to step 3:
23 goes into 153 6 times with a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 138 from 153 leaves us with 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 23

Let's proceed to step 4:
If we divide 158 by 23, we get 6 and a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 166.0
Subtract 138 from 158 to get 20.
Bring next digit (5) of the dividend behind the 20 and repeat the process: 205 / 23

Going ahead to step 5:
23 can be fit into 205 8 times, resulting in a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 1668.0
Subtracting 184 from 205 leaves us with 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 23

Advancing to step 6:
If we divide 211 by 23, we get 9 and a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 16689.0
Subtract 207 from 211 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
23 goes into 40 1 times with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 16689.1
If we subtract 23 from 40, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 8:
If we divide 170 by 23, we get 7 and a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 16689.17
If we take 161 away from 170, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
When dividing 90 by 23, we get 3 with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 16689.173
If we take 69 away from 90, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 10:
When dividing 210 by 23, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 16689.1739
Deduct 207 from 210 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 11:
The number 23 fits into 30 1 times, leaving a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 16689.17391
Deduct 23 from 30 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 12:
If we divide 70 by 23, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 16689.173913
Subtract 69 from 70 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 13:
If we divide 10 by 23, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 16689.173913
If we take 0 away from 10, 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.

Let's proceed to step 14:
100 divided by 23 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 16689.17391304
Subtracting 92 from 100 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 16689.17391304 and a remainder of 8e-09.
