We're dividing 912579 by 40 
Our goal is to divide 912579 by 40.

Step 1:
40 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 40

Moving on to step 2:
40 can be fit into 91 2 times, resulting in a remainder of 11.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 80 from 91 to get 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 40

On to step 3:
40 goes into 112 2 times with a remainder of 32.
The next digit of our result is 2. 
Result so far: 22.0
Subtracting 80 from 112 leaves us with 32.
Bring next digit (5) of the dividend behind the 32 and repeat the process: 325 / 40

On to step 4:
325 divided by 40 is 8 with a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 228.0
If we take 320 away from 325, we end up with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 40

On to step 5:
The number 40 fits into 57 1 times, leaving a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 2281.0
If we take 40 away from 57, we end up with 17.
Take the next digit (9) from the dividend and append it to 17, then repeat: 179 / 40

Let's proceed to step 6:
40 can be fit into 179 4 times, resulting in a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 22814.0
Deduct 160 from 179 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
The number 40 fits into 190 4 times, leaving a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 22814.4
Deduct 160 from 190 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
The number 40 fits into 300 7 times, leaving a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 22814.47
Subtracting 280 from 300 leaves us 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.

Let's proceed to step 9:
If we divide 200 by 40, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 22814.475
The remainder is 0 after subtracting 200 from 200.
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 10:
0 divided by 40 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 22814.475
The remainder is 0 after subtracting 0 from 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 11:
0 divided by 40 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 22814.475
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.

Our division results in 22814.475 with a remaining 0.0.
