20828136 ÷ 581 
We're looking to find how many times 581 goes into 20828136.

Step 1:
2 divided by 581 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 581

Going ahead to step 2:
If we divide 20 by 581, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Take the next digit (8) from the dividend and append it to 20, then repeat: 208 / 581

On to step 3:
581 goes into 208 0 times with 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 (2) from the dividend, attach it to 208 and continue: 2082 / 581

Step 4:
581 goes into 2082 3 times with a remainder of 339.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 1743 from 2082 leaves us with 339.
Take the next digit (8) from the dividend and append it to 339, then repeat: 3398 / 581

Let's proceed to step 5:
The number 581 fits into 3398 5 times, leaving a remainder of 493.
The next digit of our result is 5. 
Result so far: 35.0
If we subtract 2905 from 3398, we get 493.
Fetch the next digit (1) from the dividend, attach it to 493 and continue: 4931 / 581

On to step 6:
581 can be fit into 4931 8 times, resulting in a remainder of 283.
The number 8 becomes the next digit in our result. 
Result so far: 358.0
Subtracting 4648 from 4931 leaves us with 283.
Append the next digit (3) from the dividend to 283 and continue with: 2833 / 581

On to step 7:
581 can be fit into 2833 4 times, resulting in a remainder of 509.
Write down 4 as next digit of the result. 
Result so far: 3584.0
Subtracting 2324 from 2833 leaves us with 509.
Include the next digit (6) from the dividend after 509, then repeat: 5096 / 581

Moving on to step 8:
581 can be fit into 5096 8 times, resulting in a remainder of 448.
The next digit of our result is 8. 
Result so far: 35848.0
If we subtract 4648 from 5096, we get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Moving on to step 9:
581 goes into 4480 7 times with a remainder of 413.
Put 7 as the next digit of the answer. 
Result so far: 35848.7
The remainder is 413 after subtracting 4067 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

On to step 10:
When dividing 4130 by 581, we get 7 with a remainder of 63.
Write down 7 as next digit of the result. 
Result so far: 35848.77
Subtracting 4067 from 4130 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The quotient of the division is 35848.77, and the remainder is 0.063.
