220780 divided by 511 
We want to figure out the number of times 220780 can be divided by 511.

Step 1:
The number 511 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 511

Step 2:
511 goes into 22 0 times with a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 22 to get 22.
Take the next digit (0) from the dividend and append it to 22, then repeat: 220 / 511

Advancing to step 3:
The number 511 fits into 220 0 times, leaving a remainder of 220.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 220, we get 220.
Include the next digit (7) from the dividend after 220, then repeat: 2207 / 511

Let's proceed to step 4:
2207 divided by 511 is 4 with a remainder of 163.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 2044 from 2207, we get 163.
Append the next digit (8) from the dividend to 163 and continue with: 1638 / 511

On to step 5:
If we divide 1638 by 511, we get 3 and a remainder of 105.
The next digit of our result is 3. 
Result so far: 43.0
Subtract 1533 from 1638 to get 105.
Append the next digit (0) from the dividend to 105 and continue with: 1050 / 511

Advancing to step 6:
511 can be fit into 1050 2 times, resulting in a remainder of 28.
The next digit of our result is 2. 
Result so far: 432.0
Subtract 1022 from 1050 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 7:
If we divide 280 by 511, we get 0 and a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 432.0
If we subtract 0 from 280, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 8:
The number 511 fits into 2800 5 times, leaving a remainder of 245.
Record the quotient 5 as the next digit in the result. 
Result so far: 432.05
If we take 2555 away from 2800, we end up with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Advancing to step 9:
When dividing 2450 by 511, we get 4 with a remainder of 406.
The next digit of our result is 4. 
Result so far: 432.054
Subtract 2044 from 2450 to get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Moving on to step 10:
511 goes into 4060 7 times with a remainder of 483.
The next digit of our result is 7. 
Result so far: 432.0547
Subtract 3577 from 4060 to get 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Advancing to step 11:
The number 511 fits into 4830 9 times, leaving a remainder of 231.
Record the quotient 9 as the next digit in the result. 
Result so far: 432.05479
Deduct 4599 from 4830 and we're left with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Advancing to step 12:
511 goes into 2310 4 times with a remainder of 266.
Put 4 as the next digit of the answer. 
Result so far: 432.054794
Subtract 2044 from 2310 to get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Let's proceed to step 13:
The number 511 fits into 2660 5 times, leaving a remainder of 105.
The number 5 becomes the next digit in our result. 
Result so far: 432.0547945
Subtracting 2555 from 2660 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 14:
When dividing 1050 by 511, we get 2 with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 432.05479452
If we take 1022 away from 1050, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 432.05479452, and the remainder is 2.8e-08.
