821403 divided by 24 
Let's see how many times 24 fits into 821403.

Let's proceed to step 1:
24 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 24

Step 2:
24 goes into 82 3 times with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 72 from 82 leaves us with 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 24

Advancing to step 3:
101 divided by 24 is 4 with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 34.0
If we subtract 96 from 101, we get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 24

Moving on to step 4:
The number 24 fits into 54 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 342.0
The remainder is 6 after subtracting 48 from 54.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 24

Advancing to step 5:
24 goes into 60 2 times with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 3422.0
The remainder is 12 after subtracting 48 from 60.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 24

Let's proceed to step 6:
When dividing 123 by 24, we get 5 with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 34225.0
Deduct 120 from 123 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
When dividing 30 by 24, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 34225.1
Subtracting 24 from 30 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
If we divide 60 by 24, we get 2 and a remainder of 12.
The next digit of our result is 2. 
Result so far: 34225.12
The remainder is 12 after subtracting 48 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
The number 24 fits into 120 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 34225.125
The remainder is 0 after subtracting 120 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
If we divide 0 by 24, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 34225.125
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
When dividing 0 by 24, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 34225.125
The remainder is 0 after subtracting 0 from 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 final outcome is 34225.125, with a leftover of 0.0.
