Let's divide 221224 by 28
We want to figure out the number of times 221224 can be divided by 28.

Advancing to step 1:
28 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 28

Moving on to step 2:
28 can be fit into 22 0 times, resulting in a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Fetch the next digit (1) from the dividend, attach it to 22 and continue: 221 / 28

Step 3:
28 goes into 221 7 times with a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 196 from 221 and we're left with 25.
Fetch the next digit (2) from the dividend, attach it to 25 and continue: 252 / 28

On to step 4:
If we divide 252 by 28, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
If we subtract 252 from 252, we get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 28

Step 5:
28 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 790.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 28

On to step 6:
The number 28 fits into 24 0 times, leaving a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 7900.0
The remainder is 24 after subtracting 0 from 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 7:
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: 7900.8
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.

Step 8:
The number 28 fits into 160 5 times, leaving a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 7900.85
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.

Let's proceed to step 9:
28 goes into 200 7 times with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 7900.857
Subtracting 196 from 200 leaves us 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 10:
28 goes into 40 1 times with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 7900.8571
If we take 28 away from 40, 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.

Advancing to step 11:
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: 7900.85714
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.

Advancing to step 12:
When dividing 80 by 28, we get 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 7900.857142
Deduct 56 from 80 and we're left 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.

Let's proceed to step 13:
28 can be fit into 240 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 7900.8571428
Subtract 224 from 240 to get 16.
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 14:
When dividing 160 by 28, we get 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 7900.85714285
If we subtract 140 from 160, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 7900.85714285, and the remainder is 2e-08.
