28357405 ÷ 531 
We want to divide 28357405 by 531.

Let's proceed to step 1:
2 divided by 531 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 531

Let's proceed to step 2:
The number 531 fits into 28 0 times, leaving a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Append the next digit (3) from the dividend to 28 and continue with: 283 / 531

Moving on to step 3:
283 divided by 531 is 0 with a remainder of 283.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 283 after subtracting 0 from 283.
Grab the next digit (5) from the dividend, add it to 283, then carry on: 2835 / 531

On to step 4:
The number 531 fits into 2835 5 times, leaving a remainder of 180.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 2655 from 2835 to get 180.
Bring next digit (7) of the dividend behind the 180 and repeat the process: 1807 / 531

On to step 5:
The number 531 fits into 1807 3 times, leaving a remainder of 214.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
The remainder is 214 after subtracting 1593 from 1807.
Include the next digit (4) from the dividend after 214, then repeat: 2144 / 531

Going ahead to step 6:
531 goes into 2144 4 times with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 534.0
If we take 2124 away from 2144, we end up with 20.
Include the next digit (0) from the dividend after 20, then repeat: 200 / 531

Let's proceed to step 7:
531 goes into 200 0 times with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 5340.0
Subtracting 0 from 200 leaves us with 200.
Fetch the next digit (5) from the dividend, attach it to 200 and continue: 2005 / 531

Step 8:
The number 531 fits into 2005 3 times, leaving a remainder of 412.
The number 3 becomes the next digit in our result. 
Result so far: 53403.0
Deduct 1593 from 2005 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Let's proceed to step 9:
If we divide 4120 by 531, we get 7 and a remainder of 403.
The next digit of our result is 7. 
Result so far: 53403.7
Subtracting 3717 from 4120 leaves us with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Step 10:
If we divide 4030 by 531, we get 7 and a remainder of 313.
Record the quotient 7 as the next digit in the result. 
Result so far: 53403.77
Subtracting 3717 from 4030 leaves us with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

The final outcome is 53403.77, with a leftover of 0.313.
