225643 ÷ 28 
We want to figure out the number of times 225643 can be divided by 28.

Let's proceed to step 1:
The number 28 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 28

Moving on to step 2:
The number 28 fits into 22 0 times, leaving 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.
Include the next digit (5) from the dividend after 22, then repeat: 225 / 28

Step 3:
If we divide 225 by 28, we get 8 and a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 1 after subtracting 224 from 225.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 28

Let's proceed to step 4:
28 goes into 16 0 times with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 80.0
Deduct 0 from 16 and we're left with 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 28

On to step 5:
164 divided by 28 is 5 with a remainder of 24.
The number 5 becomes the next digit in our result. 
Result so far: 805.0
Deduct 140 from 164 and we're left with 24.
Take the next digit (3) from the dividend and append it to 24, then repeat: 243 / 28

Going ahead to step 6:
The number 28 fits into 243 8 times, leaving a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 8058.0
Subtract 224 from 243 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
190 divided by 28 is 6 with a remainder of 22.
The next digit of our result is 6. 
Result so far: 8058.6
If we subtract 168 from 190, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
28 goes into 220 7 times with a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 8058.67
If we take 196 away from 220, 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.

Let's proceed to step 9:
28 goes into 240 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 8058.678
Subtracting 224 from 240 leaves us 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.

Moving on to step 10:
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: 8058.6785
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.

On to step 11:
200 divided by 28 is 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 8058.67857
If we take 196 away from 200, we end up 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 12:
The number 28 fits into 40 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 8058.678571
Subtract 28 from 40 to get 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 13:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 8058.6785714
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.

Step 14:
80 divided by 28 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 8058.67857142
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 8058.67857142 and a remainder of 2.4e-08.
