302940 divided by 40 
Let's see how many times 40 fits into 302940.

Going ahead to step 1:
The number 40 fits into 3 0 times, leaving 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.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 40

Step 2:
40 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 40

On to step 3:
40 can be fit into 302 7 times, resulting in a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 280 from 302 leaves us with 22.
Take the next digit (9) from the dividend and append it to 22, then repeat: 229 / 40

Advancing to step 4:
40 goes into 229 5 times with a remainder of 29.
Write down 5 as next digit of the result. 
Result so far: 75.0
Deduct 200 from 229 and we're left with 29.
Take the next digit (4) from the dividend and append it to 29, then repeat: 294 / 40

Let's proceed to step 5:
When dividing 294 by 40, we get 7 with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 757.0
If we take 280 away from 294, we end up with 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 40

On to step 6:
40 can be fit into 140 3 times, resulting in a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 7573.0
Deduct 120 from 140 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 7:
The number 40 fits into 200 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 7573.5
If we subtract 200 from 200, 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.

Advancing to step 8:
When dividing 0 by 40, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7573.5
If we take 0 away from 0, 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.

Moving on to step 9:
0 divided by 40 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7573.5
Subtract 0 from 0 to 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.

The final result is 7573.5 with a remainder of 0.0.
