We look at the division of 439469 by 23 
Let's see how many times 23 fits into 439469.

Step 1:
When dividing 4 by 23, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 23

Going ahead to step 2:
43 divided by 23 is 1 with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 23 from 43 and we're left with 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 23

On to step 3:
When dividing 209 by 23, we get 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 207 from 209 and we're left with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 23

Advancing to step 4:
23 goes into 24 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 191.0
The remainder is 1 after subtracting 23 from 24.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 23

Advancing to step 5:
When dividing 16 by 23, we get 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 1910.0
If we subtract 0 from 16, we get 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 23

Let's proceed to step 6:
23 goes into 169 7 times with a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 19107.0
The remainder is 8 after subtracting 161 from 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
23 goes into 80 3 times with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 19107.3
If we take 69 away from 80, we end up with 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:
110 divided by 23 is 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 19107.34
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:
23 can be fit into 180 7 times, resulting in a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 19107.347
If we take 161 away from 180, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 10:
190 divided by 23 is 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 19107.3478
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.

Advancing to step 11:
The number 23 fits into 60 2 times, leaving a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 19107.34782
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.

Moving on to step 12:
23 can be fit into 140 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 19107.347826
If we take 138 away from 140, we end up with 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.
The number 0 becomes the next digit in our result. 
Result so far: 19107.347826
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.

Step 14:
200 divided by 23 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 19107.34782608
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.

The quotient of the division is 19107.34782608, and the remainder is 1.6e-08.
