We're dividing 34640517 by 863 
Our goal is to divide 34640517 by 863.

Going ahead to step 1:
863 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 863

On to step 2:
863 goes into 34 0 times with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Include the next digit (6) from the dividend after 34, then repeat: 346 / 863

Advancing to step 3:
863 can be fit into 346 0 times, resulting in a remainder of 346.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 346, we end up with 346.
Include the next digit (4) from the dividend after 346, then repeat: 3464 / 863

Step 4:
If we divide 3464 by 863, we get 4 and a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 3452 away from 3464, we end up with 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 863

Moving on to step 5:
120 divided by 863 is 0 with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 40.0
If we take 0 away from 120, we end up with 120.
Bring next digit (5) of the dividend behind the 120 and repeat the process: 1205 / 863

Let's proceed to step 6:
863 goes into 1205 1 times with a remainder of 342.
The next digit of our result is 1. 
Result so far: 401.0
Subtract 863 from 1205 to get 342.
Append the next digit (1) from the dividend to 342 and continue with: 3421 / 863

Step 7:
If we divide 3421 by 863, we get 3 and a remainder of 832.
The number 3 becomes the next digit in our result. 
Result so far: 4013.0
If we subtract 2589 from 3421, we get 832.
Grab the next digit (7) from the dividend, add it to 832, then carry on: 8327 / 863

On to step 8:
The number 863 fits into 8327 9 times, leaving a remainder of 560.
Write down 9 as next digit of the result. 
Result so far: 40139.0
If we subtract 7767 from 8327, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 9:
863 goes into 5600 6 times with a remainder of 422.
Put 6 as the next digit of the answer. 
Result so far: 40139.6
If we subtract 5178 from 5600, we get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Moving on to step 10:
When dividing 4220 by 863, we get 4 with a remainder of 768.
Write down 4 as next digit of the result. 
Result so far: 40139.64
If we take 3452 away from 4220, we end up with 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Moving on to step 11:
The number 863 fits into 7680 8 times, leaving a remainder of 776.
Put 8 as the next digit of the answer. 
Result so far: 40139.648
The remainder is 776 after subtracting 6904 from 7680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

On to step 12:
863 goes into 7760 8 times with a remainder of 856.
The number 8 becomes the next digit in our result. 
Result so far: 40139.6488
If we take 6904 away from 7760, we end up with 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8560, and continue the process.

The final result is 40139.6488 with a remainder of 0.00856.
