We look at the division of 2086586 by 511 
We want to figure out the number of times 2086586 can be divided by 511.

Going ahead to step 1:
The number 511 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 511

Moving on to step 2:
511 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Take the next digit (8) from the dividend and append it to 20, then repeat: 208 / 511

Let's proceed to step 3:
511 can be fit into 208 0 times, resulting in a remainder of 208.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 208, we get 208.
Fetch the next digit (6) from the dividend, attach it to 208 and continue: 2086 / 511

Going ahead to step 4:
If we divide 2086 by 511, we get 4 and a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 2044 from 2086 to get 42.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 511

On to step 5:
511 goes into 425 0 times with a remainder of 425.
Write down 0 as next digit of the result. 
Result so far: 40.0
If we subtract 0 from 425, we get 425.
Grab the next digit (8) from the dividend, add it to 425, then carry on: 4258 / 511

Going ahead to step 6:
The number 511 fits into 4258 8 times, leaving a remainder of 170.
Record the quotient 8 as the next digit in the result. 
Result so far: 408.0
If we take 4088 away from 4258, we end up with 170.
Append the next digit (6) from the dividend to 170 and continue with: 1706 / 511

Moving on to step 7:
1706 divided by 511 is 3 with a remainder of 173.
Write down 3 as next digit of the result. 
Result so far: 4083.0
The remainder is 173 after subtracting 1533 from 1706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Moving on to step 8:
511 goes into 1730 3 times with a remainder of 197.
The number 3 becomes the next digit in our result. 
Result so far: 4083.3
Subtract 1533 from 1730 to get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

On to step 9:
If we divide 1970 by 511, we get 3 and a remainder of 437.
Use 3 as the next digit of our solution. 
Result so far: 4083.33
Subtracting 1533 from 1970 leaves us with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

The quotient of the division is 4083.33, and the remainder is 0.437.
