577859 ÷ 28 
We want to figure out the number of times 577859 can be divided by 28.

Step 1:
If we divide 5 by 28, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 28

Step 2:
When dividing 57 by 28, we get 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 56 from 57 and we're left with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 28

Advancing to step 3:
If we divide 17 by 28, we get 0 and a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 17 leaves us with 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 28

Step 4:
If we divide 178 by 28, we get 6 and a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 206.0
Subtracting 168 from 178 leaves us with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 28

On to step 5:
105 divided by 28 is 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 2063.0
Deduct 84 from 105 and we're left with 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 28

Let's proceed to step 6:
The number 28 fits into 219 7 times, leaving a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 20637.0
The remainder is 23 after subtracting 196 from 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
28 can be fit into 230 8 times, resulting in a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 20637.8
If we subtract 224 from 230, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
The number 28 fits into 60 2 times, leaving a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 20637.82
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
28 goes into 40 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 20637.821
The remainder is 12 after subtracting 28 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 20637.8214
Subtracting 112 from 120 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
80 divided by 28 is 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 20637.82142
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
28 goes into 240 8 times with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 20637.821428
If we take 224 away from 240, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
28 goes into 160 5 times with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 20637.8214285
Subtract 140 from 160 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
28 can be fit into 200 7 times, resulting in a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 20637.82142857
The remainder is 4 after subtracting 196 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 20637.82142857, with a leftover of 4e-09.
