626639 divided by 28 
Let's see how many times 28 fits into 626639.

Going ahead to step 1:
The number 28 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 28

Step 2:
When dividing 62 by 28, we get 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 56 away from 62, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 28

Let's proceed to step 3:
The number 28 fits into 66 2 times, leaving a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we subtract 56 from 66, we get 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 28

Moving on to step 4:
If we divide 106 by 28, we get 3 and a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 223.0
If we subtract 84 from 106, we get 22.
Append the next digit (3) from the dividend to 22 and continue with: 223 / 28

On to step 5:
28 goes into 223 7 times with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 2237.0
The remainder is 27 after subtracting 196 from 223.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 28

Let's proceed to step 6:
279 divided by 28 is 9 with a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 22379.0
The remainder is 27 after subtracting 252 from 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 7:
If we divide 270 by 28, we get 9 and a remainder of 18.
The next digit of our result is 9. 
Result so far: 22379.9
Deduct 252 from 270 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
180 divided by 28 is 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 22379.96
If we take 168 away from 180, 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.

Step 9:
28 goes into 120 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 22379.964
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.

Let's proceed to step 10:
28 can be fit into 80 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 22379.9642
If we subtract 56 from 80, 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.

Going ahead to step 11:
The number 28 fits into 240 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 22379.96428
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.

On to step 12:
When dividing 160 by 28, we get 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 22379.964285
Subtracting 140 from 160 leaves us 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.

Moving on to step 13:
If we divide 200 by 28, we get 7 and a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 22379.9642857
If we subtract 196 from 200, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
28 goes into 40 1 times with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 22379.96428571
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.

After the division, we end up with 22379.96428571 and a remainder of 1.2e-08.
