We look at the division of 43042285 by 511 
We're looking to find how many times 511 goes into 43042285.

Step 1:
511 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 511

Moving on to step 2:
43 divided by 511 is 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Append the next digit (0) from the dividend to 43 and continue with: 430 / 511

Step 3:
430 divided by 511 is 0 with a remainder of 430.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 430 and we're left with 430.
Include the next digit (4) from the dividend after 430, then repeat: 4304 / 511

Going ahead to step 4:
511 can be fit into 4304 8 times, resulting in a remainder of 216.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 4088 away from 4304, we end up with 216.
Fetch the next digit (2) from the dividend, attach it to 216 and continue: 2162 / 511

Step 5:
If we divide 2162 by 511, we get 4 and a remainder of 118.
Write down 4 as next digit of the result. 
Result so far: 84.0
The remainder is 118 after subtracting 2044 from 2162.
Append the next digit (2) from the dividend to 118 and continue with: 1182 / 511

Let's proceed to step 6:
511 goes into 1182 2 times with a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 842.0
Subtract 1022 from 1182 to get 160.
Fetch the next digit (8) from the dividend, attach it to 160 and continue: 1608 / 511

Let's proceed to step 7:
The number 511 fits into 1608 3 times, leaving a remainder of 75.
Record the quotient 3 as the next digit in the result. 
Result so far: 8423.0
If we subtract 1533 from 1608, we get 75.
Grab the next digit (5) from the dividend, add it to 75, then carry on: 755 / 511

Let's proceed to step 8:
If we divide 755 by 511, we get 1 and a remainder of 244.
The next digit of our result is 1. 
Result so far: 84231.0
If we subtract 511 from 755, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Let's proceed to step 9:
511 goes into 2440 4 times with a remainder of 396.
The next digit of our result is 4. 
Result so far: 84231.4
If we subtract 2044 from 2440, we get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Going ahead to step 10:
The number 511 fits into 3960 7 times, leaving a remainder of 383.
Put 7 as the next digit of the answer. 
Result so far: 84231.47
If we subtract 3577 from 3960, we get 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Going ahead to step 11:
511 goes into 3830 7 times with a remainder of 253.
Use 7 as the next digit of our solution. 
Result so far: 84231.477
If we take 3577 away from 3830, we end up with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

The final result is 84231.477 with a remainder of 0.0253.
