We're dividing 35402685 by 863 
Let's see how many times 863 fits into 35402685.

Going ahead to step 1:
When dividing 3 by 863, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 863

Moving on to step 2:
If we divide 35 by 863, we get 0 and a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Grab the next digit (4) from the dividend, add it to 35, then carry on: 354 / 863

Moving on to step 3:
The number 863 fits into 354 0 times, leaving a remainder of 354.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 354, we get 354.
Include the next digit (0) from the dividend after 354, then repeat: 3540 / 863

Advancing to step 4:
If we divide 3540 by 863, we get 4 and a remainder of 88.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 3452 from 3540 leaves us with 88.
Bring next digit (2) of the dividend behind the 88 and repeat the process: 882 / 863

Going ahead to step 5:
When dividing 882 by 863, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Subtract 863 from 882 to get 19.
Bring next digit (6) of the dividend behind the 19 and repeat the process: 196 / 863

On to step 6:
196 divided by 863 is 0 with a remainder of 196.
Record the quotient 0 as the next digit in the result. 
Result so far: 410.0
Subtract 0 from 196 to get 196.
Grab the next digit (8) from the dividend, add it to 196, then carry on: 1968 / 863

Advancing to step 7:
1968 divided by 863 is 2 with a remainder of 242.
Put 2 as the next digit of the answer. 
Result so far: 4102.0
If we take 1726 away from 1968, we end up with 242.
Grab the next digit (5) from the dividend, add it to 242, then carry on: 2425 / 863

Let's proceed to step 8:
If we divide 2425 by 863, we get 2 and a remainder of 699.
The number 2 becomes the next digit in our result. 
Result so far: 41022.0
Subtract 1726 from 2425 to get 699.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6990, and continue the process.

Moving on to step 9:
863 can be fit into 6990 8 times, resulting in a remainder of 86.
Use 8 as the next digit of our solution. 
Result so far: 41022.8
Subtract 6904 from 6990 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 10:
When dividing 860 by 863, we get 0 with a remainder of 860.
Record the quotient 0 as the next digit in the result. 
Result so far: 41022.8
Deduct 0 from 860 and we're left with 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

Advancing to step 11:
863 goes into 8600 9 times with a remainder of 833.
Use 9 as the next digit of our solution. 
Result so far: 41022.809
Subtract 7767 from 8600 to get 833.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8330, and continue the process.

Moving on to step 12:
If we divide 8330 by 863, we get 9 and a remainder of 563.
Put 9 as the next digit of the answer. 
Result so far: 41022.8099
If we take 7767 away from 8330, we end up with 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

Our division results in 41022.8099 with a remaining 0.00563.
