Let's divide 435641 by 40
We're looking to find how many times 40 goes into 435641.

Moving on to step 1:
When dividing 4 by 40, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 40

Advancing to step 2:
43 divided by 40 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 3 after subtracting 40 from 43.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 40

Advancing to step 3:
40 goes into 35 0 times with a remainder of 35.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 35 to get 35.
Grab the next digit (6) from the dividend, add it to 35, then carry on: 356 / 40

Let's proceed to step 4:
The number 40 fits into 356 8 times, leaving a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
The remainder is 36 after subtracting 320 from 356.
Include the next digit (4) from the dividend after 36, then repeat: 364 / 40

Step 5:
The number 40 fits into 364 9 times, leaving a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 1089.0
If we subtract 360 from 364, we get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 40

Step 6:
The number 40 fits into 41 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 10891.0
If we take 40 away from 41, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
When dividing 10 by 40, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 10891.0
If we take 0 away from 10, we end up 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.

Step 8:
The number 40 fits into 100 2 times, leaving a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 10891.02
Deduct 80 from 100 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 9:
The number 40 fits into 200 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 10891.025
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.

Going ahead to step 10:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10891.025
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.

Moving on to step 11:
If we divide 0 by 40, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10891.025
If we take 0 away from 0, 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.

The final outcome is 10891.025, with a leftover of 0.0.
