We're dividing 521665 by 24 
We want to divide 521665 by 24.

On to step 1:
24 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 24

Advancing to step 2:
52 divided by 24 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 2.0
If we take 48 away from 52, we end up with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 24

Moving on to step 3:
If we divide 41 by 24, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 21.0
Subtract 24 from 41 to get 17.
Fetch the next digit (6) from the dividend, attach it to 17 and continue: 176 / 24

Step 4:
The number 24 fits into 176 7 times, leaving a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 217.0
If we take 168 away from 176, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 24

Going ahead to step 5:
24 goes into 86 3 times with a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 2173.0
Deduct 72 from 86 and we're left with 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 24

Advancing to step 6:
145 divided by 24 is 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 21736.0
The remainder is 1 after subtracting 144 from 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
The number 24 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 21736.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
24 can be fit into 100 4 times, resulting in a remainder of 4.
The next digit of our result is 4. 
Result so far: 21736.04
Deduct 96 from 100 and we're left 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.

Moving 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: 21736.041
Subtract 24 from 40 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.

Advancing to step 10:
If we divide 160 by 24, we get 6 and a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 21736.0416
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.

Let's proceed to step 11:
When dividing 160 by 24, we get 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 21736.04166
Subtracting 144 from 160 leaves us 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.

In conclusion, the division gives 21736.04166 with a balance of 1.6e-05.
