We divide 290330 by 23
The aim is to understand the frequency of 23 in 290330.

Going ahead to step 1:
2 divided by 23 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 23

Step 2:
If we divide 29 by 23, we get 1 and a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 6 after subtracting 23 from 29.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 23

Going ahead to step 3:
If we divide 60 by 23, we get 2 and a remainder of 14.
The next digit of our result is 2. 
Result so far: 12.0
If we take 46 away from 60, we end up with 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 23

Moving on to step 4:
23 goes into 143 6 times with a remainder of 5.
The next digit of our result is 6. 
Result so far: 126.0
Subtracting 138 from 143 leaves us with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 23

Let's proceed to step 5:
The number 23 fits into 53 2 times, leaving a remainder of 7.
The next digit of our result is 2. 
Result so far: 1262.0
The remainder is 7 after subtracting 46 from 53.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 23

Going ahead to step 6:
23 can be fit into 70 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 12623.0
Subtract 69 from 70 to 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.

Advancing to step 7:
When dividing 10 by 23, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 12623.0
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.

Going ahead to step 8:
If we divide 100 by 23, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 12623.04
Subtracting 92 from 100 leaves us 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.

Moving on to step 9:
When dividing 80 by 23, we get 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 12623.043
If we take 69 away from 80, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 10:
When dividing 110 by 23, we get 4 with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 12623.0434
If we take 92 away from 110, we end up 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.

Let's proceed to step 11:
If we divide 180 by 23, we get 7 and a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 12623.04347
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.

Moving on to step 12:
23 goes into 190 8 times with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 12623.043478
If we subtract 184 from 190, we get 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 13:
When dividing 60 by 23, we get 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 12623.0434782
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.

Moving on to step 14:
23 goes into 140 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 12623.04347826
If we subtract 138 from 140, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 12623.04347826 and a remainder of 2e-09.
