65903924 ÷ 23 
The aim is to understand the frequency of 23 in 65903924.

Advancing to step 1:
When dividing 6 by 23, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 23

Moving on to step 2:
The number 23 fits into 65 2 times, leaving a remainder of 19.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 46 from 65 leaves us with 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 23

Moving on to step 3:
The number 23 fits into 199 8 times, leaving a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we subtract 184 from 199, we get 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 23

Advancing to step 4:
The number 23 fits into 150 6 times, leaving a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 286.0
Subtract 138 from 150 to get 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 23

Moving on to step 5:
The number 23 fits into 123 5 times, leaving a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 2865.0
Subtract 115 from 123 to get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 23

On to step 6:
If we divide 89 by 23, we get 3 and a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 28653.0
If we subtract 69 from 89, we get 20.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 23

Step 7:
When dividing 202 by 23, we get 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 286538.0
Subtracting 184 from 202 leaves us with 18.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 23

Advancing to step 8:
If we divide 184 by 23, we get 8 and a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 2865388.0
Subtract 184 from 184 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
The number 23 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2865388.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
23 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2865388.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 2865388.0 with a remainder of 0.0.
