353315 ÷ 40 
We want to divide 353315 by 40.

Advancing to step 1:
When dividing 3 by 40, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 40

Going ahead to step 2:
40 can be fit into 35 0 times, resulting in a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 40

Advancing to step 3:
If we divide 353 by 40, we get 8 and a remainder of 33.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 320 from 353 and we're left with 33.
Bring next digit (3) of the dividend behind the 33 and repeat the process: 333 / 40

Advancing to step 4:
If we divide 333 by 40, we get 8 and a remainder of 13.
Put 8 as the next digit of the answer. 
Result so far: 88.0
If we take 320 away from 333, we end up with 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 40

Moving on to step 5:
When dividing 131 by 40, we get 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 883.0
Subtract 120 from 131 to get 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 40

Let's proceed to step 6:
115 divided by 40 is 2 with a remainder of 35.
Put 2 as the next digit of the answer. 
Result so far: 8832.0
Deduct 80 from 115 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 7:
40 can be fit into 350 8 times, resulting in a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 8832.8
If we subtract 320 from 350, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
40 can be fit into 300 7 times, resulting in a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 8832.87
If we subtract 280 from 300, we get 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 9:
If we divide 200 by 40, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 8832.875
Subtract 200 from 200 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.

Let's proceed to step 10:
40 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8832.875
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.

Moving on to step 11:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8832.875
If we subtract 0 from 0, 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.

The final result is 8832.875 with a remainder of 0.0.
