434385 ÷ 40 
We want to divide 434385 by 40.

On to step 1:
4 divided by 40 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 40

Step 2:
If we divide 43 by 40, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 3 after subtracting 40 from 43.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 40

On to step 3:
40 goes into 34 0 times with a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 34 and we're left with 34.
Fetch the next digit (3) from the dividend, attach it to 34 and continue: 343 / 40

Going ahead to step 4:
The number 40 fits into 343 8 times, leaving a remainder of 23.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
Subtract 320 from 343 to get 23.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 40

Going ahead to step 5:
40 goes into 238 5 times with a remainder of 38.
Record the quotient 5 as the next digit in the result. 
Result so far: 1085.0
Subtracting 200 from 238 leaves us with 38.
Take the next digit (5) from the dividend and append it to 38, then repeat: 385 / 40

Step 6:
385 divided by 40 is 9 with a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 10859.0
Subtract 360 from 385 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 7:
The number 40 fits into 250 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 10859.6
If we subtract 240 from 250, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
If we divide 100 by 40, we get 2 and a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 10859.62
If we subtract 80 from 100, 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.

Moving on to step 9:
When dividing 200 by 40, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 10859.625
If we take 200 away from 200, 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.

Let's proceed to step 10:
When dividing 0 by 40, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10859.625
Deduct 0 from 0 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.

Going ahead to step 11:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10859.625
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.

The final result is 10859.625 with a remainder of 0.0.
