We're dividing 640658 by 24 
We're looking to find how many times 24 goes into 640658.

Let's proceed to step 1:
24 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 24

On to step 2:
64 divided by 24 is 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 48 from 64 to get 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 24

Going ahead to step 3:
24 goes into 160 6 times with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 26.0
Subtracting 144 from 160 leaves us with 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 24

Let's proceed to step 4:
24 can be fit into 166 6 times, resulting in a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 266.0
Subtract 144 from 166 to get 22.
Grab the next digit (5) from the dividend, add it to 22, then carry on: 225 / 24

Advancing to step 5:
When dividing 225 by 24, we get 9 with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 2669.0
If we subtract 216 from 225, we get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 24

Advancing to step 6:
98 divided by 24 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 26694.0
If we take 96 away from 98, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
The number 24 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 26694.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
24 can be fit into 200 8 times, resulting in a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 26694.08
Subtract 192 from 200 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
If we divide 80 by 24, we get 3 and a remainder of 8.
The next digit of our result is 3. 
Result so far: 26694.083
Subtracting 72 from 80 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 10:
24 goes into 80 3 times with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 26694.0833
Deduct 72 from 80 and we're left 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.

In conclusion, the division gives 26694.0833 with a balance of 8e-05.
