24729664 divided by 861 
We want to figure out the number of times 24729664 can be divided by 861.

Going ahead to step 1:
861 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 861

Let's proceed to step 2:
24 divided by 861 is 0 with a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 24 to get 24.
Grab the next digit (7) from the dividend, add it to 24, then carry on: 247 / 861

Let's proceed to step 3:
The number 861 fits into 247 0 times, leaving a remainder of 247.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 247 leaves us with 247.
Fetch the next digit (2) from the dividend, attach it to 247 and continue: 2472 / 861

On to step 4:
861 goes into 2472 2 times with a remainder of 750.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 1722 away from 2472, we end up with 750.
Bring next digit (9) of the dividend behind the 750 and repeat the process: 7509 / 861

Step 5:
The number 861 fits into 7509 8 times, leaving a remainder of 621.
The next digit of our result is 8. 
Result so far: 28.0
Subtract 6888 from 7509 to get 621.
Append the next digit (6) from the dividend to 621 and continue with: 6216 / 861

Advancing to step 6:
6216 divided by 861 is 7 with a remainder of 189.
The next digit of our result is 7. 
Result so far: 287.0
Subtract 6027 from 6216 to get 189.
Append the next digit (6) from the dividend to 189 and continue with: 1896 / 861

Moving on to step 7:
1896 divided by 861 is 2 with a remainder of 174.
Put 2 as the next digit of the answer. 
Result so far: 2872.0
If we subtract 1722 from 1896, we get 174.
Take the next digit (4) from the dividend and append it to 174, then repeat: 1744 / 861

Moving on to step 8:
The number 861 fits into 1744 2 times, leaving a remainder of 22.
The next digit of our result is 2. 
Result so far: 28722.0
Subtract 1722 from 1744 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
When dividing 220 by 861, we get 0 with a remainder of 220.
Write down 0 as next digit of the result. 
Result so far: 28722.0
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 10:
2200 divided by 861 is 2 with a remainder of 478.
The number 2 becomes the next digit in our result. 
Result so far: 28722.02
If we take 1722 away from 2200, we end up with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Advancing to step 11:
If we divide 4780 by 861, we get 5 and a remainder of 475.
Use 5 as the next digit of our solution. 
Result so far: 28722.025
Subtract 4305 from 4780 to get 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Step 12:
If we divide 4750 by 861, we get 5 and a remainder of 445.
Use 5 as the next digit of our solution. 
Result so far: 28722.0255
Subtracting 4305 from 4750 leaves us with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

The final result is 28722.0255 with a remainder of 0.00445.
