42509924 divided by 868 
Let's see how many times 868 fits into 42509924.

Moving on to step 1:
The number 868 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 868

Step 2:
42 divided by 868 is 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Append the next digit (5) from the dividend to 42 and continue with: 425 / 868

Let's proceed to step 3:
868 can be fit into 425 0 times, resulting in a remainder of 425.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 425, we get 425.
Fetch the next digit (0) from the dividend, attach it to 425 and continue: 4250 / 868

Moving on to step 4:
If we divide 4250 by 868, we get 4 and a remainder of 778.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 3472 from 4250, we get 778.
Include the next digit (9) from the dividend after 778, then repeat: 7789 / 868

On to step 5:
868 can be fit into 7789 8 times, resulting in a remainder of 845.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Subtracting 6944 from 7789 leaves us with 845.
Append the next digit (9) from the dividend to 845 and continue with: 8459 / 868

Moving on to step 6:
When dividing 8459 by 868, we get 9 with a remainder of 647.
Record the quotient 9 as the next digit in the result. 
Result so far: 489.0
If we take 7812 away from 8459, we end up with 647.
Take the next digit (2) from the dividend and append it to 647, then repeat: 6472 / 868

On to step 7:
6472 divided by 868 is 7 with a remainder of 396.
The number 7 becomes the next digit in our result. 
Result so far: 4897.0
If we subtract 6076 from 6472, we get 396.
Bring next digit (4) of the dividend behind the 396 and repeat the process: 3964 / 868

Advancing to step 8:
868 goes into 3964 4 times with a remainder of 492.
Use 4 as the next digit of our solution. 
Result so far: 48974.0
Subtract 3472 from 3964 to get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Going ahead to step 9:
If we divide 4920 by 868, we get 5 and a remainder of 580.
The number 5 becomes the next digit in our result. 
Result so far: 48974.5
Subtracting 4340 from 4920 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Step 10:
If we divide 5800 by 868, we get 6 and a remainder of 592.
Record the quotient 6 as the next digit in the result. 
Result so far: 48974.56
If we subtract 5208 from 5800, we get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

On to step 11:
When dividing 5920 by 868, we get 6 with a remainder of 712.
The number 6 becomes the next digit in our result. 
Result so far: 48974.566
Subtract 5208 from 5920 to get 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

The final result is 48974.566 with a remainder of 0.0712.
