4288663 divided by 868 
We want to divide 4288663 by 868.

Let's proceed to step 1:
If we divide 4 by 868, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 868

Advancing to step 2:
42 divided by 868 is 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 868

On to step 3:
If we divide 428 by 868, we get 0 and a remainder of 428.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 428 and we're left with 428.
Bring next digit (8) of the dividend behind the 428 and repeat the process: 4288 / 868

On to step 4:
868 can be fit into 4288 4 times, resulting in a remainder of 816.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 3472 away from 4288, we end up with 816.
Grab the next digit (6) from the dividend, add it to 816, then carry on: 8166 / 868

Advancing to step 5:
868 goes into 8166 9 times with a remainder of 354.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Deduct 7812 from 8166 and we're left with 354.
Grab the next digit (6) from the dividend, add it to 354, then carry on: 3546 / 868

Moving on to step 6:
868 goes into 3546 4 times with a remainder of 74.
Write down 4 as next digit of the result. 
Result so far: 494.0
The remainder is 74 after subtracting 3472 from 3546.
Fetch the next digit (3) from the dividend, attach it to 74 and continue: 743 / 868

Let's proceed to step 7:
If we divide 743 by 868, we get 0 and a remainder of 743.
Record the quotient 0 as the next digit in the result. 
Result so far: 4940.0
Subtract 0 from 743 to get 743.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7430, and continue the process.

Advancing to step 8:
868 goes into 7430 8 times with a remainder of 486.
Put 8 as the next digit of the answer. 
Result so far: 4940.8
Subtracting 6944 from 7430 leaves us with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Moving on to step 9:
If we divide 4860 by 868, we get 5 and a remainder of 520.
The next digit of our result is 5. 
Result so far: 4940.85
If we subtract 4340 from 4860, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 10:
868 can be fit into 5200 5 times, resulting in a remainder of 860.
The next digit of our result is 5. 
Result so far: 4940.855
If we subtract 4340 from 5200, we get 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

The final result is 4940.855 with a remainder of 0.086.
