We look at the division of 42509845 by 868 
We're looking to find how many times 868 goes into 42509845.

Moving on to step 1:
When dividing 4 by 868, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 868

Moving on to step 2:
868 can be fit into 42 0 times, resulting in a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 868

On to step 3:
425 divided by 868 is 0 with a remainder of 425.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 425 and we're left with 425.
Append the next digit (0) from the dividend to 425 and continue with: 4250 / 868

Going ahead to step 4:
The number 868 fits into 4250 4 times, leaving a remainder of 778.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 3472 from 4250, we get 778.
Bring next digit (9) of the dividend behind the 778 and repeat the process: 7789 / 868

Let's proceed to step 5:
When dividing 7789 by 868, we get 8 with a remainder of 845.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Subtract 6944 from 7789 to get 845.
Bring next digit (8) of the dividend behind the 845 and repeat the process: 8458 / 868

On to step 6:
868 goes into 8458 9 times with a remainder of 646.
The number 9 becomes the next digit in our result. 
Result so far: 489.0
If we take 7812 away from 8458, we end up with 646.
Fetch the next digit (4) from the dividend, attach it to 646 and continue: 6464 / 868

Going ahead to step 7:
The number 868 fits into 6464 7 times, leaving a remainder of 388.
Write down 7 as next digit of the result. 
Result so far: 4897.0
If we subtract 6076 from 6464, we get 388.
Grab the next digit (5) from the dividend, add it to 388, then carry on: 3885 / 868

Moving on to step 8:
3885 divided by 868 is 4 with a remainder of 413.
The next digit of our result is 4. 
Result so far: 48974.0
Deduct 3472 from 3885 and we're left with 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Moving on to step 9:
868 can be fit into 4130 4 times, resulting in a remainder of 658.
Write down 4 as next digit of the result. 
Result so far: 48974.4
Subtract 3472 from 4130 to get 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Let's proceed to step 10:
868 goes into 6580 7 times with a remainder of 504.
The number 7 becomes the next digit in our result. 
Result so far: 48974.47
Deduct 6076 from 6580 and we're left with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Going ahead to step 11:
When dividing 5040 by 868, we get 5 with a remainder of 700.
Use 5 as the next digit of our solution. 
Result so far: 48974.475
If we subtract 4340 from 5040, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Going ahead to step 12:
The number 868 fits into 7000 8 times, leaving a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 48974.4758
If we take 6944 away from 7000, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 13:
868 goes into 560 0 times with a remainder of 560.
The number 0 becomes the next digit in our result. 
Result so far: 48974.4758
If we take 0 away from 560, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 14:
868 can be fit into 5600 6 times, resulting in a remainder of 392.
Put 6 as the next digit of the answer. 
Result so far: 48974.475806
Subtract 5208 from 5600 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Step 15:
868 can be fit into 3920 4 times, resulting in a remainder of 448.
Use 4 as the next digit of our solution. 
Result so far: 48974.4758064
The remainder is 448 after subtracting 3472 from 3920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

On to step 16:
When dividing 4480 by 868, we get 5 with a remainder of 140.
The number 5 becomes the next digit in our result. 
Result so far: 48974.47580645
Deduct 4340 from 4480 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

After the division, we end up with 48974.47580645 and a remainder of 1.4e-07.
