615886 ÷ 28 
Our goal is to divide 615886 by 28.

Moving on to step 1:
The number 28 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 28

On to step 2:
28 goes into 61 2 times with a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 56 from 61, we get 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 28

Let's proceed to step 3:
55 divided by 28 is 1 with a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we subtract 28 from 55, we get 27.
Bring next digit (8) of the dividend behind the 27 and repeat the process: 278 / 28

Advancing to step 4:
When dividing 278 by 28, we get 9 with a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 219.0
If we subtract 252 from 278, we get 26.
Fetch the next digit (8) from the dividend, attach it to 26 and continue: 268 / 28

Step 5:
The number 28 fits into 268 9 times, leaving a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 2199.0
If we take 252 away from 268, we end up with 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 28

On to step 6:
The number 28 fits into 166 5 times, leaving a remainder of 26.
Put 5 as the next digit of the answer. 
Result so far: 21995.0
If we subtract 140 from 166, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 7:
28 goes into 260 9 times with a remainder of 8.
The next digit of our result is 9. 
Result so far: 21995.9
Subtracting 252 from 260 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 8:
The number 28 fits into 80 2 times, leaving a remainder of 24.
The next digit of our result is 2. 
Result so far: 21995.92
Subtract 56 from 80 to get 24.
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 9:
The number 28 fits into 240 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 21995.928
If we subtract 224 from 240, we get 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 10:
160 divided by 28 is 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 21995.9285
If we subtract 140 from 160, we 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.

Let's proceed to step 11:
28 can be fit into 200 7 times, resulting in a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 21995.92857
Deduct 196 from 200 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
The number 28 fits into 40 1 times, leaving a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 21995.928571
If we take 28 away from 40, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 21995.9285714
If we subtract 112 from 120, we get 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 14:
28 goes into 80 2 times with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 21995.92857142
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.

The final outcome is 21995.92857142, with a leftover of 2.4e-08.
