Let's divide 43586540 by 285
We want to divide 43586540 by 285.

Advancing to step 1:
285 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 285

Step 2:
If we divide 43 by 285, we get 0 and a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Include the next digit (5) from the dividend after 43, then repeat: 435 / 285

Advancing to step 3:
285 goes into 435 1 times with a remainder of 150.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 285 from 435 to get 150.
Bring next digit (8) of the dividend behind the 150 and repeat the process: 1508 / 285

Let's proceed to step 4:
When dividing 1508 by 285, we get 5 with a remainder of 83.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we take 1425 away from 1508, we end up with 83.
Include the next digit (6) from the dividend after 83, then repeat: 836 / 285

Step 5:
285 goes into 836 2 times with a remainder of 266.
Write down 2 as next digit of the result. 
Result so far: 152.0
The remainder is 266 after subtracting 570 from 836.
Grab the next digit (5) from the dividend, add it to 266, then carry on: 2665 / 285

Moving on to step 6:
285 goes into 2665 9 times with a remainder of 100.
Record the quotient 9 as the next digit in the result. 
Result so far: 1529.0
If we subtract 2565 from 2665, we get 100.
Fetch the next digit (4) from the dividend, attach it to 100 and continue: 1004 / 285

Let's proceed to step 7:
If we divide 1004 by 285, we get 3 and a remainder of 149.
Put 3 as the next digit of the answer. 
Result so far: 15293.0
Subtracting 855 from 1004 leaves us with 149.
Bring next digit (0) of the dividend behind the 149 and repeat the process: 1490 / 285

Going ahead to step 8:
The number 285 fits into 1490 5 times, leaving a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 152935.0
The remainder is 65 after subtracting 1425 from 1490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 9:
When dividing 650 by 285, we get 2 with a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 152935.2
Subtracting 570 from 650 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 10:
285 can be fit into 800 2 times, resulting in a remainder of 230.
The number 2 becomes the next digit in our result. 
Result so far: 152935.22
Subtracting 570 from 800 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

After the division, we end up with 152935.22 and a remainder of 0.23.
