We're dividing 642424 by 28 
Let's see how many times 28 fits into 642424.

Let's proceed to step 1:
When dividing 6 by 28, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 28

Let's proceed to step 2:
28 can be fit into 64 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 56 from 64, we get 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 28

On to step 3:
28 goes into 82 2 times with a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we subtract 56 from 82, we get 26.
Include the next digit (4) from the dividend after 26, then repeat: 264 / 28

Let's proceed to step 4:
264 divided by 28 is 9 with a remainder of 12.
The next digit of our result is 9. 
Result so far: 229.0
The remainder is 12 after subtracting 252 from 264.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 28

Going ahead to step 5:
122 divided by 28 is 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 2294.0
Subtract 112 from 122 to get 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 28

Going ahead to step 6:
104 divided by 28 is 3 with a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 22943.0
Subtracting 84 from 104 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 7:
The number 28 fits into 200 7 times, leaving a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 22943.7
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.

Step 8:
28 goes into 40 1 times with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 22943.71
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.

Advancing to step 9:
If we divide 120 by 28, we get 4 and a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 22943.714
Deduct 112 from 120 and we're left 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 10:
The number 28 fits into 80 2 times, leaving a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 22943.7142
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 11:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 22943.71428
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.

On to step 12:
If we divide 160 by 28, we get 5 and a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 22943.714285
Deduct 140 from 160 and we're left 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.

Step 13:
If we divide 200 by 28, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 22943.7142857
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.

Moving on to step 14:
28 goes into 40 1 times with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 22943.71428571
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 22943.71428571 and a remainder of 1.2e-08.
