302144 divided by 40 
Our goal is to divide 302144 by 40.

On to step 1:
40 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 40

Let's proceed to step 2:
30 divided by 40 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 40

Let's proceed to step 3:
40 goes into 302 7 times with a remainder of 22.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 22 after subtracting 280 from 302.
Bring next digit (1) of the dividend behind the 22 and repeat the process: 221 / 40

Advancing to step 4:
If we divide 221 by 40, we get 5 and a remainder of 21.
Write down 5 as next digit of the result. 
Result so far: 75.0
The remainder is 21 after subtracting 200 from 221.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 40

Advancing to step 5:
214 divided by 40 is 5 with a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 755.0
Subtract 200 from 214 to get 14.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 40

On to step 6:
144 divided by 40 is 3 with a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 7553.0
The remainder is 24 after subtracting 120 from 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
240 divided by 40 is 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 7553.6
Subtracting 240 from 240 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.

Let's proceed to step 8:
0 divided by 40 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7553.6
Subtracting 0 from 0 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.

On to step 9:
40 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7553.6
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 7553.6 with a remainder of 0.0.
