We're dividing 644233 by 24 
The aim is to understand the frequency of 24 in 644233.

Going ahead to step 1:
6 divided by 24 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 24

Let's proceed to step 2:
When dividing 64 by 24, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 16 after subtracting 48 from 64.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 24

On to step 3:
The number 24 fits into 164 6 times, leaving a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 26.0
If we take 144 away from 164, we end up with 20.
Append the next digit (2) from the dividend to 20 and continue with: 202 / 24

On to step 4:
24 goes into 202 8 times with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 268.0
The remainder is 10 after subtracting 192 from 202.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 24

Let's proceed to step 5:
When dividing 103 by 24, we get 4 with a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 2684.0
The remainder is 7 after subtracting 96 from 103.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 24

Let's proceed to step 6:
24 goes into 73 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 26843.0
Deduct 72 from 73 and we're left 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.

On to step 7:
If we divide 10 by 24, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 26843.0
If we take 0 away from 10, we end up 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.

Step 8:
100 divided by 24 is 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 26843.04
Subtracting 96 from 100 leaves us 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.

On to step 9:
40 divided by 24 is 1 with a remainder of 16.
The next digit of our result is 1. 
Result so far: 26843.041
If we take 24 away from 40, 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 10:
If we divide 160 by 24, we get 6 and a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 26843.0416
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
When dividing 160 by 24, we get 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 26843.04166
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 26843.04166, and the remainder is 1.6e-05.
