We look at the division of 86503 by 40 
Let's see how many times 40 fits into 86503.

Moving on to step 1:
40 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 40

Moving on to step 2:
If we divide 86 by 40, we get 2 and a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 80 from 86, we get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 40

Moving on to step 3:
When dividing 65 by 40, we get 1 with a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtracting 40 from 65 leaves us with 25.
Fetch the next digit (0) from the dividend, attach it to 25 and continue: 250 / 40

Advancing to step 4:
When dividing 250 by 40, we get 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 216.0
If we subtract 240 from 250, we get 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 40

Let's proceed to step 5:
If we divide 103 by 40, we get 2 and a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 2162.0
Subtracting 80 from 103 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 6:
If we divide 230 by 40, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 2162.5
Subtracting 200 from 230 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
If we divide 300 by 40, we get 7 and a remainder of 20.
The next digit of our result is 7. 
Result so far: 2162.57
Deduct 280 from 300 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
40 goes into 200 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 2162.575
If we take 200 away from 200, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
40 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 2162.575
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
The number 40 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 2162.575
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 2162.575 with a balance of 0.0.
