Let's divide 26623891 by 863
We want to divide 26623891 by 863.

Advancing to step 1:
If we divide 2 by 863, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 863

Going ahead to step 2:
26 divided by 863 is 0 with a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 26 and we're left with 26.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 863

Going ahead to step 3:
266 divided by 863 is 0 with a remainder of 266.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 266, we get 266.
Bring next digit (2) of the dividend behind the 266 and repeat the process: 2662 / 863

Let's proceed to step 4:
863 goes into 2662 3 times with a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 2589 away from 2662, we end up with 73.
Bring next digit (3) of the dividend behind the 73 and repeat the process: 733 / 863

On to step 5:
863 can be fit into 733 0 times, resulting in a remainder of 733.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Subtract 0 from 733 to get 733.
Fetch the next digit (8) from the dividend, attach it to 733 and continue: 7338 / 863

Advancing to step 6:
7338 divided by 863 is 8 with a remainder of 434.
The number 8 becomes the next digit in our result. 
Result so far: 308.0
The remainder is 434 after subtracting 6904 from 7338.
Include the next digit (9) from the dividend after 434, then repeat: 4349 / 863

On to step 7:
When dividing 4349 by 863, we get 5 with a remainder of 34.
Put 5 as the next digit of the answer. 
Result so far: 3085.0
If we take 4315 away from 4349, we end up with 34.
Bring next digit (1) of the dividend behind the 34 and repeat the process: 341 / 863

Step 8:
863 goes into 341 0 times with a remainder of 341.
The next digit of our result is 0. 
Result so far: 30850.0
If we take 0 away from 341, we end up with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Going ahead to step 9:
The number 863 fits into 3410 3 times, leaving a remainder of 821.
The number 3 becomes the next digit in our result. 
Result so far: 30850.3
If we take 2589 away from 3410, we end up with 821.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8210, and continue the process.

Going ahead to step 10:
8210 divided by 863 is 9 with a remainder of 443.
Put 9 as the next digit of the answer. 
Result so far: 30850.39
The remainder is 443 after subtracting 7767 from 8210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

On to step 11:
863 goes into 4430 5 times with a remainder of 115.
Put 5 as the next digit of the answer. 
Result so far: 30850.395
Deduct 4315 from 4430 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 12:
The number 863 fits into 1150 1 times, leaving a remainder of 287.
The next digit of our result is 1. 
Result so far: 30850.3951
If we take 863 away from 1150, we end up with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

On to step 13:
863 goes into 2870 3 times with a remainder of 281.
The number 3 becomes the next digit in our result. 
Result so far: 30850.39513
The remainder is 281 after subtracting 2589 from 2870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Moving on to step 14:
863 can be fit into 2810 3 times, resulting in a remainder of 221.
The number 3 becomes the next digit in our result. 
Result so far: 30850.395133
If we subtract 2589 from 2810, we get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

The final result is 30850.395133 with a remainder of 2.21e-05.
