661436 ÷ 24 
We want to divide 661436 by 24.

Advancing to step 1:
If we divide 6 by 24, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 24

Step 2:
The number 24 fits into 66 2 times, leaving a remainder of 18.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 48 from 66, we get 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 24

Advancing to step 3:
181 divided by 24 is 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 27.0
If we subtract 168 from 181, we get 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 24

Let's proceed to step 4:
If we divide 134 by 24, we get 5 and a remainder of 14.
The next digit of our result is 5. 
Result so far: 275.0
The remainder is 14 after subtracting 120 from 134.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 24

On to step 5:
If we divide 143 by 24, we get 5 and a remainder of 23.
The next digit of our result is 5. 
Result so far: 2755.0
The remainder is 23 after subtracting 120 from 143.
Include the next digit (6) from the dividend after 23, then repeat: 236 / 24

Advancing to step 6:
236 divided by 24 is 9 with a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 27559.0
The remainder is 20 after subtracting 216 from 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
200 divided by 24 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 27559.8
Deduct 192 from 200 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.

Moving on to step 8:
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: 27559.83
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.

Going ahead to step 9:
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: 27559.833
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.

The quotient of the division is 27559.833, and the remainder is 0.0008.
