621678 ÷ 28 
We're looking to find how many times 28 goes into 621678.

Step 1:
28 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 28

Moving on to step 2:
28 goes into 62 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 56 from 62 to get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 28

Moving on to step 3:
The number 28 fits into 61 2 times, leaving a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we take 56 away from 61, we end up with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 28

Going ahead to step 4:
When dividing 56 by 28, we get 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 222.0
Deduct 56 from 56 and we're left with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 28

On to step 5:
7 divided by 28 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 2220.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 28

Going ahead to step 6:
28 can be fit into 78 2 times, resulting in a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 22202.0
If we take 56 away from 78, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
28 goes into 220 7 times with a remainder of 24.
The next digit of our result is 7. 
Result so far: 22202.7
If we subtract 196 from 220, we 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.

Step 8:
240 divided by 28 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 22202.78
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:
160 divided by 28 is 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 22202.785
The remainder is 20 after subtracting 140 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
28 can be fit into 200 7 times, resulting in a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 22202.7857
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 11:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 22202.78571
Deduct 28 from 40 and we're left 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.

Moving on to step 12:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 22202.785714
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.

Let's proceed to step 13:
If we divide 80 by 28, we get 2 and a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 22202.7857142
If we take 56 away from 80, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
When dividing 240 by 28, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 22202.78571428
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.

In conclusion, the division gives 22202.78571428 with a balance of 1.6e-08.
