303872 divided by 40 
We want to divide 303872 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
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:
If we divide 30 by 40, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 40

Going ahead to step 3:
303 divided by 40 is 7 with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 280 from 303, we get 23.
Grab the next digit (8) from the dividend, add it to 23, then carry on: 238 / 40

Step 4:
40 goes into 238 5 times with a remainder of 38.
Put 5 as the next digit of the answer. 
Result so far: 75.0
The remainder is 38 after subtracting 200 from 238.
Bring next digit (7) of the dividend behind the 38 and repeat the process: 387 / 40

Let's proceed to step 5:
When dividing 387 by 40, we get 9 with a remainder of 27.
The next digit of our result is 9. 
Result so far: 759.0
If we take 360 away from 387, we end up with 27.
Grab the next digit (2) from the dividend, add it to 27, then carry on: 272 / 40

Advancing to step 6:
If we divide 272 by 40, we get 6 and a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 7596.0
If we take 240 away from 272, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 7:
If we divide 320 by 40, we get 8 and a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 7596.8
Deduct 320 from 320 and we're left 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.

Step 8:
0 divided by 40 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7596.8
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.

Going ahead to step 9:
If we divide 0 by 40, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 7596.8
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.

The final outcome is 7596.8, with a leftover of 0.0.
