52087901 ÷ 863 
Let's see how many times 863 fits into 52087901.

On to step 1:
If we divide 5 by 863, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 863

On to step 2:
863 goes into 52 0 times with a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Fetch the next digit (0) from the dividend, attach it to 52 and continue: 520 / 863

Going ahead to step 3:
520 divided by 863 is 0 with a remainder of 520.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 520, we get 520.
Bring next digit (8) of the dividend behind the 520 and repeat the process: 5208 / 863

Let's proceed to step 4:
The number 863 fits into 5208 6 times, leaving a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 5178 from 5208 to get 30.
Grab the next digit (7) from the dividend, add it to 30, then carry on: 307 / 863

Moving on to step 5:
The number 863 fits into 307 0 times, leaving a remainder of 307.
Put 0 as the next digit of the answer. 
Result so far: 60.0
If we subtract 0 from 307, we get 307.
Fetch the next digit (9) from the dividend, attach it to 307 and continue: 3079 / 863

Moving on to step 6:
If we divide 3079 by 863, we get 3 and a remainder of 490.
Record the quotient 3 as the next digit in the result. 
Result so far: 603.0
The remainder is 490 after subtracting 2589 from 3079.
Fetch the next digit (0) from the dividend, attach it to 490 and continue: 4900 / 863

On to step 7:
The number 863 fits into 4900 5 times, leaving a remainder of 585.
Put 5 as the next digit of the answer. 
Result so far: 6035.0
Deduct 4315 from 4900 and we're left with 585.
Bring next digit (1) of the dividend behind the 585 and repeat the process: 5851 / 863

On to step 8:
When dividing 5851 by 863, we get 6 with a remainder of 673.
Record the quotient 6 as the next digit in the result. 
Result so far: 60356.0
If we take 5178 away from 5851, we end up with 673.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6730, and continue the process.

Going ahead to step 9:
6730 divided by 863 is 7 with a remainder of 689.
Write down 7 as next digit of the result. 
Result so far: 60356.7
If we take 6041 away from 6730, we end up with 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

Let's proceed to step 10:
863 can be fit into 6890 7 times, resulting in a remainder of 849.
The number 7 becomes the next digit in our result. 
Result so far: 60356.77
Subtracting 6041 from 6890 leaves us with 849.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8490, and continue the process.

Our division results in 60356.77 with a remaining 0.849.
