Let's divide 30457 by 23
We're looking to find how many times 23 goes into 30457.

Step 1:
23 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 23

On to step 2:
The number 23 fits into 30 1 times, leaving a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 7 after subtracting 23 from 30.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 23

Going ahead to step 3:
23 goes into 74 3 times with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 69 from 74, we get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 23

Step 4:
23 goes into 55 2 times with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 132.0
The remainder is 9 after subtracting 46 from 55.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 23

Moving on to step 5:
When dividing 97 by 23, we get 4 with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 1324.0
If we subtract 92 from 97, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 6:
If we divide 50 by 23, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 1324.2
If we subtract 46 from 50, we get 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 7:
40 divided by 23 is 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1324.21
The remainder is 17 after subtracting 23 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 8:
The number 23 fits into 170 7 times, leaving a remainder of 9.
The next digit of our result is 7. 
Result so far: 1324.217
Deduct 161 from 170 and we're left 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 9:
The number 23 fits into 90 3 times, leaving a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 1324.2173
Subtract 69 from 90 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 10:
When dividing 210 by 23, we get 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 1324.21739
Subtracting 207 from 210 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
30 divided by 23 is 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1324.217391
Deduct 23 from 30 and we're left 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.

Going ahead to step 12:
The number 23 fits into 70 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 1324.2173913
If we take 69 away from 70, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 13:
10 divided by 23 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 1324.2173913
Subtracting 0 from 10 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.

The quotient of the division is 1324.2173913, and the remainder is 1e-08.
