438821 ÷ 23 
Let's see how many times 23 fits into 438821.

Going ahead to step 1:
The number 23 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 23

Going ahead to step 2:
When dividing 43 by 23, we get 1 with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 23 away from 43, we end up with 20.
Bring next digit (8) of the dividend behind the 20 and repeat the process: 208 / 23

Let's proceed to step 3:
23 can be fit into 208 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtract 207 from 208 to get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 23

Step 4:
23 can be fit into 18 0 times, resulting in a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 190.0
Deduct 0 from 18 and we're left with 18.
Take the next digit (2) from the dividend and append it to 18, then repeat: 182 / 23

Step 5:
If we divide 182 by 23, we get 7 and a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 1907.0
If we subtract 161 from 182, we get 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 23

Going ahead to step 6:
23 can be fit into 211 9 times, resulting in a remainder of 4.
The next digit of our result is 9. 
Result so far: 19079.0
If we subtract 207 from 211, we 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.

Advancing to step 7:
23 can be fit into 40 1 times, resulting in a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 19079.1
If we take 23 away from 40, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 8:
23 can be fit into 170 7 times, resulting in a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 19079.17
Subtract 161 from 170 to get 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:
If we divide 90 by 23, we get 3 and a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 19079.173
Subtract 69 from 90 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 10:
210 divided by 23 is 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 19079.1739
Subtract 207 from 210 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 11:
30 divided by 23 is 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 19079.17391
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.

Advancing to step 12:
The number 23 fits into 70 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 19079.173913
The remainder is 1 after subtracting 69 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 13:
If we divide 10 by 23, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 19079.173913
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:
23 goes into 100 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 19079.17391304
If we subtract 92 from 100, 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.

The final outcome is 19079.17391304, with a leftover of 8e-09.
