We're dividing 435645 by 40 
We want to divide 435645 by 40.

Step 1:
When dividing 4 by 40, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 40

Moving on to step 2:
43 divided by 40 is 1 with 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 (5) from the dividend to 3 and continue with: 35 / 40

Let's proceed to step 3:
40 goes into 35 0 times with a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 35, we end up with 35.
Take the next digit (6) from the dividend and append it to 35, then repeat: 356 / 40

Let's proceed to step 4:
356 divided by 40 is 8 with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 108.0
If we take 320 away from 356, we end up with 36.
Bring next digit (4) of the dividend behind the 36 and repeat the process: 364 / 40

Going ahead to step 5:
The number 40 fits into 364 9 times, leaving a remainder of 4.
The next digit of our result is 9. 
Result so far: 1089.0
Deduct 360 from 364 and we're left with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 40

Going ahead to step 6:
45 divided by 40 is 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 10891.0
Subtract 40 from 45 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
50 divided by 40 is 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 10891.1
Deduct 40 from 50 and we're left with 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:
The number 40 fits into 100 2 times, leaving a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 10891.12
The remainder is 20 after subtracting 80 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing 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: 10891.125
If we subtract 200 from 200, 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.

Let's proceed to step 10:
40 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10891.125
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:
If we divide 0 by 40, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10891.125
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.

In conclusion, the division gives 10891.125 with a balance of 0.0.
