We're dividing 575590 by 40 
We're looking to find how many times 40 goes into 575590.

Step 1:
If we divide 5 by 40, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 40

Let's proceed to step 2:
57 divided by 40 is 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 40 from 57, we get 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 40

Advancing to step 3:
175 divided by 40 is 4 with a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 160 from 175, we get 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 40

Moving on to step 4:
40 can be fit into 155 3 times, resulting in a remainder of 35.
The next digit of our result is 3. 
Result so far: 143.0
If we take 120 away from 155, we end up with 35.
Take the next digit (9) from the dividend and append it to 35, then repeat: 359 / 40

Step 5:
When dividing 359 by 40, we get 8 with a remainder of 39.
Use 8 as the next digit of our solution. 
Result so far: 1438.0
Deduct 320 from 359 and we're left with 39.
Take the next digit (0) from the dividend and append it to 39, then repeat: 390 / 40

Let's proceed to step 6:
40 can be fit into 390 9 times, resulting in a remainder of 30.
Use 9 as the next digit of our solution. 
Result so far: 14389.0
If we take 360 away from 390, we end up 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.

On to step 7:
40 can be fit into 300 7 times, resulting in a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 14389.7
If we subtract 280 from 300, we get 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 8:
If we divide 200 by 40, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 14389.75
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.

Step 9:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 14389.75
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.

Going ahead to step 10:
0 divided by 40 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 14389.75
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 quotient of the division is 14389.75, and the remainder is 0.0.
