We're dividing 573594 by 40 
We're looking to find how many times 40 goes into 573594.

Moving on to step 1:
40 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 40

Advancing to step 2:
57 divided by 40 is 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 40 from 57 to get 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 40

Let's proceed to step 3:
The number 40 fits into 173 4 times, leaving a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 160 away from 173, we end up with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 40

On to step 4:
40 goes into 135 3 times with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 143.0
If we take 120 away from 135, we end up with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 40

Let's proceed to step 5:
The number 40 fits into 159 3 times, leaving a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 1433.0
Subtract 120 from 159 to get 39.
Fetch the next digit (4) from the dividend, attach it to 39 and continue: 394 / 40

On to step 6:
394 divided by 40 is 9 with a remainder of 34.
Put 9 as the next digit of the answer. 
Result so far: 14339.0
The remainder is 34 after subtracting 360 from 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 7:
If we divide 340 by 40, we get 8 and a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 14339.8
Subtract 320 from 340 to 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.

Let's proceed to step 8:
200 divided by 40 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 14339.85
Subtract 200 from 200 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.
Use 0 as the next digit of our solution. 
Result so far: 14339.85
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.

Advancing to step 10:
40 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 14339.85
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.

After the division, we end up with 14339.85 and a remainder of 0.0.
