We're dividing 433488 by 40 
Let's see how many times 40 fits into 433488.

Going ahead to step 1:
The number 40 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 40

Let's proceed to step 2:
43 divided by 40 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 40 from 43 and we're left with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 40

Moving on to step 3:
If we divide 33 by 40, we get 0 and a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 33 and we're left with 33.
Take the next digit (4) from the dividend and append it to 33, then repeat: 334 / 40

Advancing to step 4:
If we divide 334 by 40, we get 8 and a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 108.0
Deduct 320 from 334 and we're left with 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 40

Step 5:
40 can be fit into 148 3 times, resulting in a remainder of 28.
Use 3 as the next digit of our solution. 
Result so far: 1083.0
Deduct 120 from 148 and we're left with 28.
Fetch the next digit (8) from the dividend, attach it to 28 and continue: 288 / 40

Let's proceed to step 6:
When dividing 288 by 40, we get 7 with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 10837.0
Subtracting 280 from 288 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
40 goes into 80 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 10837.2
If we subtract 80 from 80, 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.

Going ahead to step 8:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10837.2
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.

Let's proceed to step 9:
When dividing 0 by 40, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10837.2
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.

The final outcome is 10837.2, with a leftover of 0.0.
