We're dividing 630302 by 40 
We want to divide 630302 by 40.

Advancing to step 1:
40 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 40

Advancing to step 2:
If we divide 63 by 40, we get 1 and a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 40 away from 63, we end up with 23.
Grab the next digit (0) from the dividend, add it to 23, then carry on: 230 / 40

Advancing to step 3:
40 goes into 230 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 200 from 230 to get 30.
Bring next digit (3) of the dividend behind the 30 and repeat the process: 303 / 40

Let's proceed to step 4:
303 divided by 40 is 7 with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 157.0
The remainder is 23 after subtracting 280 from 303.
Bring next digit (0) of the dividend behind the 23 and repeat the process: 230 / 40

Moving on to step 5:
40 goes into 230 5 times with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 1575.0
The remainder is 30 after subtracting 200 from 230.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 40

Moving on to step 6:
40 goes into 302 7 times with a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 15757.0
Subtracting 280 from 302 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
When dividing 220 by 40, we get 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 15757.5
If we take 200 away from 220, we end up 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.

Let's proceed to step 8:
200 divided by 40 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 15757.55
Subtracting 200 from 200 leaves us 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.

Our division results in 15757.55 with a remaining 0.0.
