421301 ÷ 23 
We want to figure out the number of times 421301 can be divided by 23.

Let's proceed to step 1:
If we divide 4 by 23, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 23

Advancing to step 2:
23 goes into 42 1 times with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 19 after subtracting 23 from 42.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 23

Step 3:
When dividing 191 by 23, we get 8 with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 184 from 191 leaves us with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 23

Advancing to step 4:
23 can be fit into 73 3 times, resulting in a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 183.0
If we subtract 69 from 73, we get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 23

Let's proceed to step 5:
23 goes into 40 1 times with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1831.0
The remainder is 17 after subtracting 23 from 40.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 23

Let's proceed to step 6:
The number 23 fits into 171 7 times, leaving a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 18317.0
Subtracting 161 from 171 leaves us 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 7:
23 goes into 100 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 18317.4
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.

Advancing to step 8:
23 goes into 80 3 times with a remainder of 11.
The next digit of our result is 3. 
Result so far: 18317.43
If we subtract 69 from 80, we get 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 9:
110 divided by 23 is 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 18317.434
Subtracting 92 from 110 leaves us 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.

Let's proceed to step 10:
180 divided by 23 is 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 18317.4347
If we subtract 161 from 180, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 11:
If we divide 190 by 23, we get 8 and a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 18317.43478
If we subtract 184 from 190, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 12:
When dividing 60 by 23, we get 2 with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 18317.434782
Deduct 46 from 60 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 13:
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: 18317.4347826
Deduct 138 from 140 and we're left 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 14:
23 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 18317.4347826
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 18317.4347826 with a remainder of 2e-08.
