Let's divide 638921 by 24
We want to figure out the number of times 638921 can be divided by 24.

Step 1:
When dividing 6 by 24, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 24

Advancing to step 2:
24 can be fit into 63 2 times, resulting in a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 48 from 63, we get 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 24

Moving on to step 3:
158 divided by 24 is 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 26.0
If we subtract 144 from 158, we get 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 24

Going ahead to step 4:
149 divided by 24 is 6 with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 266.0
If we take 144 away from 149, we end up with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 24

Advancing to step 5:
24 can be fit into 52 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 2662.0
Subtract 48 from 52 to get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 24

Let's proceed to step 6:
When dividing 41 by 24, we get 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 26621.0
Deduct 24 from 41 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
The number 24 fits into 170 7 times, leaving a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 26621.7
If we subtract 168 from 170, we get 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 8:
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: 26621.7
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
If we divide 200 by 24, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 26621.708
If we take 192 away from 200, we end up 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:
When dividing 80 by 24, we get 3 with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 26621.7083
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.

Step 11:
24 goes into 80 3 times with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 26621.70833
Subtract 72 from 80 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.

The quotient of the division is 26621.70833, and the remainder is 8e-06.
