We divide 422588 by 23
Let's see how many times 23 fits into 422588.

Advancing to step 1:
If we divide 4 by 23, we get 0 and 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.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 23

Going ahead to step 2:
If we divide 42 by 23, we get 1 and a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 23 from 42 to get 19.
Take the next digit (2) from the dividend and append it to 19, then repeat: 192 / 23

Let's proceed to step 3:
192 divided by 23 is 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Deduct 184 from 192 and we're left with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 23

Moving on to step 4:
85 divided by 23 is 3 with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 183.0
Subtract 69 from 85 to get 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 23

Step 5:
168 divided by 23 is 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 1837.0
Deduct 161 from 168 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 23

Going ahead to step 6:
78 divided by 23 is 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 18373.0
If we take 69 away from 78, 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.

Going ahead to step 7:
The number 23 fits into 90 3 times, leaving a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 18373.3
Deduct 69 from 90 and we're left 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.

Step 8:
The number 23 fits into 210 9 times, leaving a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 18373.39
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.

Moving on to step 9:
23 can be fit into 30 1 times, resulting in a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 18373.391
If we take 23 away from 30, we end up 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.

Step 10:
23 goes into 70 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 18373.3913
If we subtract 69 from 70, we 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.

Moving on to step 11:
23 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 18373.3913
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.

Step 12:
If we divide 100 by 23, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 18373.391304
If we take 92 away from 100, we end up 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.

Step 13:
23 can be fit into 80 3 times, resulting in a remainder of 11.
The next digit of our result is 3. 
Result so far: 18373.3913043
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.

Step 14:
The number 23 fits into 110 4 times, leaving a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 18373.39130434
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.

Our division results in 18373.39130434 with a remaining 1.8e-08.
