Fetch the next digit (6) from the dividend, attach it to 125 and continue: 1256 / 863

Advancing to step 4:
863 goes into 1256 1 times with a remainder of 393.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 863 from 1256 to get 393.
Fetch the next digit (9) from the dividend, attach it to 393 and continue: 3939 / 863

Moving on to step 5:
When dividing 3939 by 863, we get 4 with a remainder of 487.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 3452 from 3939 and we're left with 487.
Grab the next digit (6) from the dividend, add it to 487, then carry on: 4876 / 863

Moving on to step 6:
863 goes into 4876 5 times with a remainder of 561.
The number 5 becomes the next digit in our result. 
Result so far: 145.0
Deduct 4315 from 4876 and we're left with 561.
Bring next digit (1) of the dividend behind the 561 and repeat the process: 5611 / 863

Step 7:
863 can be fit into 5611 6 times, resulting in a remainder of 433.
The number 6 becomes the next digit in our result. 
Result so far: 1456.0
If we subtract 5178 from 5611, we get 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Step 8:
863 goes into 4330 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 1456.5
Subtract 4315 from 4330 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
150 divided by 863 is 0 with a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 1456.5
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 10:
863 can be fit into 1500 1 times, resulting in a remainder of 637.
Write down 1 as next digit of the result. 
Result so far: 1456.501
If we subtract 863 from 1500, we get 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

Advancing to step 11:
If we divide 6370 by 863, we get 7 and a remainder of 329.
Write down 7 as next digit of the result. 
Result so far: 1456.5017
Subtract 6041 from 6370 to get 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Advancing to step 12:
When dividing 3290 by 863, we get 3 with a remainder of 701.
The next digit of our result is 3. 
Result so far: 1456.50173
The remainder is 701 after subtracting 2589 from 3290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7010, and continue the process.

Step 13:
7010 divided by 863 is 8 with a remainder of 106.
The number 8 becomes the next digit in our result. 
Result so far: 1456.501738
If we subtract 6904 from 7010, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 14:
When dividing 1060 by 863, we get 1 with a remainder of 197.
The number 1 becomes the next digit in our result. 
Result so far: 1456.5017381
The remainder is 197 after subtracting 863 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

On to step 15:
The number 863 fits into 1970 2 times, leaving a remainder of 244.
Use 2 as the next digit of our solution. 
Result so far: 1456.50173812
The remainder is 244 after subtracting 1726 from 1970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

The final result is 1456.50173812 with a remainder of 2.44e-07.
