We look at the division of 203631 by 40 
Let's see how many times 40 fits into 203631.

Going ahead to step 1:
If we divide 2 by 40, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 40

Let's proceed to step 2:
The number 40 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 40

Going ahead to step 3:
When dividing 203 by 40, we get 5 with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 200 from 203 leaves us with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 40

Going ahead to step 4:
When dividing 36 by 40, we get 0 with a remainder of 36.
The next digit of our result is 0. 
Result so far: 50.0
Subtracting 0 from 36 leaves us with 36.
Include the next digit (3) from the dividend after 36, then repeat: 363 / 40

Step 5:
The number 40 fits into 363 9 times, leaving a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 509.0
Deduct 360 from 363 and we're left with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 40

Advancing to step 6:
40 can be fit into 31 0 times, resulting in a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 5090.0
If we subtract 0 from 31, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 7:
When dividing 310 by 40, we get 7 with a remainder of 30.
The next digit of our result is 7. 
Result so far: 5090.7
If we take 280 away from 310, we end up 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.

On to step 8:
If we divide 300 by 40, we get 7 and a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 5090.77
Subtract 280 from 300 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 5090.77, and the remainder is 0.02.
