The next digit of our result is 0. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Bring next digit (4) of the dividend behind the 42 and repeat the process: 424 / 868

Going ahead to step 3:
868 can be fit into 424 0 times, resulting in a remainder of 424.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 424 after subtracting 0 from 424.
Grab the next digit (5) from the dividend, add it to 424, then carry on: 4245 / 868

Moving on to step 4:
4245 divided by 868 is 4 with a remainder of 773.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 3472 away from 4245, we end up with 773.
Fetch the next digit (3) from the dividend, attach it to 773 and continue: 7733 / 868

Advancing to step 5:
7733 divided by 868 is 8 with a remainder of 789.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
If we subtract 6944 from 7733, we get 789.
Fetch the next digit (8) from the dividend, attach it to 789 and continue: 7898 / 868

Going ahead to step 6:
868 goes into 7898 9 times with a remainder of 86.
The number 9 becomes the next digit in our result. 
Result so far: 489.0
The remainder is 86 after subtracting 7812 from 7898.
Fetch the next digit (4) from the dividend, attach it to 86 and continue: 864 / 868

Moving on to step 7:
The number 868 fits into 864 0 times, leaving a remainder of 864.
The next digit of our result is 0. 
Result so far: 4890.0
If we take 0 away from 864, we end up with 864.
Fetch the next digit (3) from the dividend, attach it to 864 and continue: 8643 / 868

Going ahead to step 8:
When dividing 8643 by 868, we get 9 with a remainder of 831.
Record the quotient 9 as the next digit in the result. 
Result so far: 48909.0
Deduct 7812 from 8643 and we're left with 831.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8310, and continue the process.

Going ahead to step 9:
If we divide 8310 by 868, we get 9 and a remainder of 498.
The number 9 becomes the next digit in our result. 
Result so far: 48909.9
Deduct 7812 from 8310 and we're left with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Let's proceed to step 10:
868 goes into 4980 5 times with a remainder of 640.
Record the quotient 5 as the next digit in the result. 
Result so far: 48909.95
Subtracting 4340 from 4980 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Advancing to step 11:
When dividing 6400 by 868, we get 7 with a remainder of 324.
Write down 7 as next digit of the result. 
Result so far: 48909.957
Subtracting 6076 from 6400 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Let's proceed to step 12:
868 can be fit into 3240 3 times, resulting in a remainder of 636.
Use 3 as the next digit of our solution. 
Result so far: 48909.9573
If we subtract 2604 from 3240, we get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Let's proceed to step 13:
The number 868 fits into 6360 7 times, leaving a remainder of 284.
Put 7 as the next digit of the answer. 
Result so far: 48909.95737
The remainder is 284 after subtracting 6076 from 6360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 14:
868 can be fit into 2840 3 times, resulting in a remainder of 236.
The number 3 becomes the next digit in our result. 
Result so far: 48909.957373
If we take 2604 away from 2840, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 15:
If we divide 2360 by 868, we get 2 and a remainder of 624.
Write down 2 as next digit of the result. 
Result so far: 48909.9573732
Subtracting 1736 from 2360 leaves us with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Going ahead to step 16:
868 goes into 6240 7 times with a remainder of 164.
The next digit of our result is 7. 
Result so far: 48909.95737327
Subtracting 6076 from 6240 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Our division results in 48909.95737327 with a remaining 1.64e-07.
