We look at the division of 641121 by 28 
We want to figure out the number of times 641121 can be divided by 28.

On to step 1:
The number 28 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 28

Moving on to step 2:
28 goes into 64 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 56 from 64 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 28

Going ahead to step 3:
The number 28 fits into 81 2 times, leaving a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Subtracting 56 from 81 leaves us with 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 28

Step 4:
28 can be fit into 251 8 times, resulting in a remainder of 27.
The next digit of our result is 8. 
Result so far: 228.0
Subtract 224 from 251 to get 27.
Include the next digit (2) from the dividend after 27, then repeat: 272 / 28

Going ahead to step 5:
The number 28 fits into 272 9 times, leaving a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 2289.0
If we subtract 252 from 272, we get 20.
Bring next digit (1) of the dividend behind the 20 and repeat the process: 201 / 28

Let's proceed to step 6:
The number 28 fits into 201 7 times, leaving a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 22897.0
Deduct 196 from 201 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
The number 28 fits into 50 1 times, leaving a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 22897.1
If we take 28 away from 50, 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 8:
220 divided by 28 is 7 with a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 22897.17
The remainder is 24 after subtracting 196 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 22897.178
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 10:
If we divide 160 by 28, we get 5 and a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 22897.1785
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.

Advancing to step 11:
28 goes into 200 7 times with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 22897.17857
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.

Advancing to step 12:
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: 22897.178571
Subtracting 28 from 40 leaves us 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:
120 divided by 28 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 22897.1785714
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.

Step 14:
When dividing 80 by 28, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 22897.17857142
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.

After the division, we end up with 22897.17857142 and a remainder of 2.4e-08.
