We're dividing 434906 by 40 
Our goal is to divide 434906 by 40.

On to step 1:
40 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 40

Moving on to step 2:
The number 40 fits into 43 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 40 away from 43, we end up with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 40

Going ahead 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
If we take 0 away from 34, we end up with 34.
Bring next digit (9) of the dividend behind the 34 and repeat the process: 349 / 40

Step 4:
When dividing 349 by 40, we get 8 with a remainder of 29.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
Subtract 320 from 349 to get 29.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 40

Advancing to step 5:
When dividing 290 by 40, we get 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 1087.0
Subtract 280 from 290 to get 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 40

Going ahead to step 6:
106 divided by 40 is 2 with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 10872.0
Deduct 80 from 106 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 7:
40 goes into 260 6 times with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 10872.6
Deduct 240 from 260 and we're left 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 goes into 200 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 10872.65
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.

Advancing to step 9:
The number 40 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10872.65
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.

Let's proceed to step 10:
40 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 10872.65
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.

After the division, we end up with 10872.65 and a remainder of 0.0.
