We're dividing 815620 by 28 
Our goal is to divide 815620 by 28.

Step 1:
When dividing 8 by 28, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 28

On to step 2:
When dividing 81 by 28, we get 2 with a remainder of 25.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 25 after subtracting 56 from 81.
Take the next digit (5) from the dividend and append it to 25, then repeat: 255 / 28

On to step 3:
The number 28 fits into 255 9 times, leaving a remainder of 3.
The next digit of our result is 9. 
Result so far: 29.0
Subtracting 252 from 255 leaves us with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 28

Step 4:
36 divided by 28 is 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 291.0
Deduct 28 from 36 and we're left with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 28

Moving on to step 5:
The number 28 fits into 82 2 times, leaving a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 2912.0
Subtract 56 from 82 to get 26.
Include the next digit (0) from the dividend after 26, then repeat: 260 / 28

Advancing to step 6:
28 goes into 260 9 times with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 29129.0
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.

Step 7:
If we divide 80 by 28, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 29129.2
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.

Let's proceed to step 8:
240 divided by 28 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 29129.28
The remainder is 16 after subtracting 224 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
28 goes into 160 5 times with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 29129.285
If we take 140 away from 160, we end up with 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 10:
The number 28 fits into 200 7 times, leaving a remainder of 4.
The next digit of our result is 7. 
Result so far: 29129.2857
If we take 196 away from 200, we end up 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.

Moving on to step 11:
If we divide 40 by 28, we get 1 and a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 29129.28571
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.

Step 12:
120 divided by 28 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 29129.285714
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
28 goes into 80 2 times with a remainder of 24.
The next digit of our result is 2. 
Result so far: 29129.2857142
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.

Advancing to step 14:
240 divided by 28 is 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 29129.28571428
Deduct 224 from 240 and we're left 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.

After the division, we end up with 29129.28571428 and a remainder of 1.6e-08.
