We look at the division of 579372 by 40 
Let's see how many times 40 fits into 579372.

On to step 1:
The number 40 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 40

Going ahead to step 2:
If we divide 57 by 40, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 40 from 57 to get 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 40

Step 3:
40 can be fit into 179 4 times, resulting in a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 160 from 179 leaves us with 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 40

On to step 4:
When dividing 193 by 40, we get 4 with a remainder of 33.
Put 4 as the next digit of the answer. 
Result so far: 144.0
If we subtract 160 from 193, we get 33.
Include the next digit (7) from the dividend after 33, then repeat: 337 / 40

Step 5:
When dividing 337 by 40, we get 8 with a remainder of 17.
Write down 8 as next digit of the result. 
Result so far: 1448.0
If we take 320 away from 337, we end up with 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 40

Step 6:
If we divide 172 by 40, we get 4 and a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 14484.0
Subtracting 160 from 172 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
The number 40 fits into 120 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 14484.3
Subtracting 120 from 120 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.

Moving on to step 8:
0 divided by 40 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 14484.3
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.

On to step 9:
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: 14484.3
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.

After the division, we end up with 14484.3 and a remainder of 0.0.
