We divide 521038 by 23
The aim is to understand the frequency of 23 in 521038.

Step 1:
23 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 23

Advancing to step 2:
If we divide 52 by 23, we get 2 and a remainder of 6.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 46 from 52 and we're left with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 23

Going ahead to step 3:
If we divide 61 by 23, we get 2 and a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Deduct 46 from 61 and we're left with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 23

On to step 4:
When dividing 150 by 23, we get 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 226.0
If we take 138 away from 150, we end up with 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 23

On to step 5:
123 divided by 23 is 5 with a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 2265.0
If we subtract 115 from 123, we get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 23

Let's proceed to step 6:
If we divide 88 by 23, we get 3 and a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 22653.0
If we subtract 69 from 88, 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.

Moving on to step 7:
23 can be fit into 190 8 times, resulting in a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 22653.8
If we take 184 away from 190, we end up 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 8:
23 can be fit into 60 2 times, resulting in a remainder of 14.
The next digit of our result is 2. 
Result so far: 22653.82
The remainder is 14 after subtracting 46 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
When dividing 140 by 23, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 22653.826
The remainder is 2 after subtracting 138 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
23 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 22653.826
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
If we divide 200 by 23, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 22653.82608
If we take 184 away from 200, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
When dividing 160 by 23, we get 6 with a remainder of 22.
The next digit of our result is 6. 
Result so far: 22653.826086
Subtracting 138 from 160 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 13:
23 can be fit into 220 9 times, resulting in a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 22653.8260869
The remainder is 13 after subtracting 207 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 14:
23 can be fit into 130 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 22653.82608695
If we subtract 115 from 130, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 22653.82608695, and the remainder is 1.5e-08.
