438789 ÷ 24 
The aim is to understand the frequency of 24 in 438789.

Going ahead to step 1:
The number 24 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 24

Advancing to step 2:
When dividing 43 by 24, we get 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 24 from 43, we get 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 24

Step 3:
If we divide 198 by 24, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 18.0
The remainder is 6 after subtracting 192 from 198.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 24

Going ahead to step 4:
24 can be fit into 67 2 times, resulting in a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 182.0
Subtracting 48 from 67 leaves us with 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 24

Let's proceed to step 5:
24 goes into 198 8 times with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 1828.0
If we subtract 192 from 198, we get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 24

Let's proceed to step 6:
If we divide 69 by 24, we get 2 and a remainder of 21.
Record the quotient 2 as the next digit in the result. 
Result so far: 18282.0
The remainder is 21 after subtracting 48 from 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
If we divide 210 by 24, we get 8 and a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 18282.8
If we take 192 away from 210, 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.

Advancing to step 8:
The number 24 fits into 180 7 times, leaving a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 18282.87
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
When dividing 120 by 24, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 18282.875
Subtracting 120 from 120 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
24 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18282.875
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.

Step 11:
When dividing 0 by 24, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 18282.875
Subtracting 0 from 0 leaves us with 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 quotient of the division is 18282.875, and the remainder is 0.0.
