We look at the division of 435606 by 40 
Let's see how many times 40 fits into 435606.

Step 1:
If we divide 4 by 40, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 40

On to step 2:
The number 40 fits into 43 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 40 away from 43, we end up with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 40

Advancing to step 3:
35 divided by 40 is 0 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.
Bring next digit (6) of the dividend behind the 35 and repeat the process: 356 / 40

On to step 4:
356 divided by 40 is 8 with a remainder of 36.
The next digit of our result is 8. 
Result so far: 108.0
Deduct 320 from 356 and we're left with 36.
Append the next digit (0) from the dividend to 36 and continue with: 360 / 40

On to step 5:
360 divided by 40 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 1089.0
Subtract 360 from 360 to get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 40

Advancing to step 6:
The number 40 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 10890.0
Deduct 0 from 6 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
The number 40 fits into 60 1 times, leaving a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 10890.1
The remainder is 20 after subtracting 40 from 60.
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 8:
When dividing 200 by 40, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 10890.15
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 9:
If we divide 0 by 40, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 10890.15
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.

Advancing to step 10:
40 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10890.15
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.

After the division, we end up with 10890.15 and a remainder of 0.0.
