Let's divide 423253 by 23
We're looking to find how many times 23 goes into 423253.

Step 1:
23 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 23

Moving on to step 2:
23 goes into 42 1 times with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 23 from 42 and we're left with 19.
Append the next digit (3) from the dividend to 19 and continue with: 193 / 23

Advancing to step 3:
193 divided by 23 is 8 with a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we take 184 away from 193, we end up with 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 23

Step 4:
23 can be fit into 92 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 184.0
Subtract 92 from 92 to get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 23

Step 5:
If we divide 5 by 23, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 1840.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 23

Going ahead to step 6:
23 can be fit into 53 2 times, resulting in a remainder of 7.
The next digit of our result is 2. 
Result so far: 18402.0
If we take 46 away from 53, 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.

Advancing to step 7:
If we divide 70 by 23, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 18402.3
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.

On to step 8:
If we divide 10 by 23, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 18402.3
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
When dividing 100 by 23, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 18402.304
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.

On to step 10:
If we divide 80 by 23, we get 3 and a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 18402.3043
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.

Let's proceed to step 11:
The number 23 fits into 110 4 times, leaving a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 18402.30434
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.

Moving on to step 12:
The number 23 fits into 180 7 times, leaving a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 18402.304347
The remainder is 19 after subtracting 161 from 180.
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 13:
If we divide 190 by 23, we get 8 and a remainder of 6.
The next digit of our result is 8. 
Result so far: 18402.3043478
Deduct 184 from 190 and we're left 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.

Let's proceed to step 14:
When dividing 60 by 23, we get 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 18402.30434782
If we take 46 away from 60, we end up 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.

Our division results in 18402.30434782 with a remaining 1.4e-08.
