We divide 490848 by 23
The aim is to understand the frequency of 23 in 490848.

Going ahead to step 1:
23 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 23

Going ahead to step 2:
If we divide 49 by 23, we get 2 and a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 46 from 49, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 23

Step 3:
23 can be fit into 30 1 times, resulting in a remainder of 7.
The next digit of our result is 1. 
Result so far: 21.0
Deduct 23 from 30 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 23

Going ahead to step 4:
23 can be fit into 78 3 times, resulting in a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 213.0
Deduct 69 from 78 and we're left with 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 23

Let's proceed to step 5:
23 can be fit into 94 4 times, resulting in a remainder of 2.
The next digit of our result is 4. 
Result so far: 2134.0
If we subtract 92 from 94, we get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 23

Advancing to step 6:
If we divide 28 by 23, we get 1 and a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 21341.0
Deduct 23 from 28 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
When dividing 50 by 23, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 21341.2
Deduct 46 from 50 and we're left with 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 8:
If we divide 40 by 23, we get 1 and a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 21341.21
If we take 23 away from 40, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
23 can be fit into 170 7 times, resulting in a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 21341.217
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.

Step 10:
23 goes into 90 3 times with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 21341.2173
The remainder is 21 after subtracting 69 from 90.
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 11:
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: 21341.21739
Deduct 207 from 210 and we're left 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.

Let's proceed to step 12:
If we divide 30 by 23, we get 1 and a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 21341.217391
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.

On to step 13:
23 can be fit into 70 3 times, resulting in a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 21341.2173913
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.

Advancing to step 14:
If we divide 10 by 23, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 21341.2173913
Deduct 0 from 10 and we're left 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 final outcome is 21341.2173913, with a leftover of 1e-08.
