Let's divide 491370 by 23
Let's see how many times 23 fits into 491370.

Step 1:
The number 23 fits into 4 0 times, leaving 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.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 23

Moving on to step 2:
23 goes into 49 2 times with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 46 away from 49, we end up with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 23

Step 3:
If we divide 31 by 23, we get 1 and a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we subtract 23 from 31, we get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 23

Going ahead to step 4:
23 goes into 83 3 times with a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 213.0
The remainder is 14 after subtracting 69 from 83.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 23

Moving on to step 5:
23 goes into 147 6 times with a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 2136.0
Deduct 138 from 147 and we're left with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 23

On to step 6:
90 divided by 23 is 3 with a remainder of 21.
The next digit of our result is 3. 
Result so far: 21363.0
Subtracting 69 from 90 leaves us 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.

Advancing to step 7:
The number 23 fits into 210 9 times, leaving a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 21363.9
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 8:
The number 23 fits into 30 1 times, leaving a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 21363.91
The remainder is 7 after subtracting 23 from 30.
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 9:
If we divide 70 by 23, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 21363.913
Subtracting 69 from 70 leaves us 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.

Let's proceed to step 10:
10 divided by 23 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 21363.913
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.

Going ahead to step 11:
23 can be fit into 100 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 21363.91304
Deduct 92 from 100 and we're left 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.

Going ahead to step 12:
The number 23 fits into 80 3 times, leaving a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 21363.913043
Subtract 69 from 80 to 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 13:
When dividing 110 by 23, we get 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 21363.9130434
If we subtract 92 from 110, we get 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 14:
23 goes into 180 7 times with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 21363.91304347
If we take 161 away from 180, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 21363.91304347, with a leftover of 1.9e-08.
