221145 ÷ 28 
We're looking to find how many times 28 goes into 221145.

Going ahead to step 1:
The number 28 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 28

Advancing to step 2:
If we divide 22 by 28, we get 0 and a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 22 and we're left with 22.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 28

On to step 3:
If we divide 221 by 28, we get 7 and a remainder of 25.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 25 after subtracting 196 from 221.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 28

Advancing to step 4:
If we divide 251 by 28, we get 8 and a remainder of 27.
Write down 8 as next digit of the result. 
Result so far: 78.0
Subtracting 224 from 251 leaves us with 27.
Grab the next digit (4) from the dividend, add it to 27, then carry on: 274 / 28

Step 5:
28 goes into 274 9 times with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 789.0
Subtracting 252 from 274 leaves us with 22.
Bring next digit (5) of the dividend behind the 22 and repeat the process: 225 / 28

Going ahead to step 6:
225 divided by 28 is 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 7898.0
Subtract 224 from 225 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
The number 28 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 7898.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
28 goes into 100 3 times with a remainder of 16.
The next digit of our result is 3. 
Result so far: 7898.03
Deduct 84 from 100 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.

Moving on to step 9:
160 divided by 28 is 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 7898.035
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.

Going ahead to step 10:
200 divided by 28 is 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 7898.0357
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.

Going ahead to step 11:
28 goes into 40 1 times with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 7898.03571
If we subtract 28 from 40, we 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.

Let's proceed to step 12:
When dividing 120 by 28, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 7898.035714
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.

Step 13:
80 divided by 28 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 7898.0357142
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 14:
28 goes into 240 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 7898.03571428
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.

The final result is 7898.03571428 with a remainder of 1.6e-08.
