915310 divided by 40 
Our goal is to divide 915310 by 40.

On to step 1:
40 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 40

Going ahead to step 2:
When dividing 91 by 40, we get 2 with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 80 from 91 and we're left with 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 40

Going ahead to step 3:
40 can be fit into 115 2 times, resulting in a remainder of 35.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Deduct 80 from 115 and we're left with 35.
Append the next digit (3) from the dividend to 35 and continue with: 353 / 40

Moving on to step 4:
The number 40 fits into 353 8 times, leaving a remainder of 33.
Record the quotient 8 as the next digit in the result. 
Result so far: 228.0
Deduct 320 from 353 and we're left with 33.
Append the next digit (1) from the dividend to 33 and continue with: 331 / 40

Step 5:
The number 40 fits into 331 8 times, leaving a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 2288.0
If we subtract 320 from 331, we get 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 40

Going ahead to step 6:
110 divided by 40 is 2 with a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 22882.0
The remainder is 30 after subtracting 80 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
40 can be fit into 300 7 times, resulting in a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 22882.7
If we take 280 away from 300, 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.

On to step 8:
40 can be fit into 200 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 22882.75
The remainder is 0 after subtracting 200 from 200.
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 9:
If we divide 0 by 40, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 22882.75
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.

Advancing to step 10:
When dividing 0 by 40, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 22882.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 22882.75 with a balance of 0.0.
