423036 divided by 23 
Our goal is to divide 423036 by 23.

Let's proceed to 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
Deduct 0 from 4 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 23

Advancing to step 2:
The number 23 fits into 42 1 times, leaving a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 23 from 42, we get 19.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 23

On to step 3:
When dividing 193 by 23, we get 8 with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we subtract 184 from 193, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 23

Advancing to step 4:
23 can be fit into 90 3 times, resulting in a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 183.0
Subtract 69 from 90 to get 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 23

Let's proceed to step 5:
23 goes into 213 9 times with a remainder of 6.
The next digit of our result is 9. 
Result so far: 1839.0
Deduct 207 from 213 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 23

Let's proceed to step 6:
When dividing 66 by 23, we get 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 18392.0
Subtract 46 from 66 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.

Going ahead to step 7:
If we divide 200 by 23, we get 8 and a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 18392.8
Subtract 184 from 200 to 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.

Moving on to step 8:
If we divide 160 by 23, we get 6 and a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 18392.86
Deduct 138 from 160 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
220 divided by 23 is 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 18392.869
If we take 207 away from 220, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 10:
The number 23 fits into 130 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 18392.8695
If we subtract 115 from 130, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
23 goes into 150 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 18392.86956
Deduct 138 from 150 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 12:
If we divide 120 by 23, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 18392.869565
If we take 115 away from 120, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
50 divided by 23 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 18392.8695652
If we take 46 away from 50, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
The number 23 fits into 40 1 times, leaving a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 18392.86956521
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.

The final result is 18392.86956521 with a remainder of 1.7e-08.
