140145 ÷ 28 
Let's see how many times 28 fits into 140145.

Step 1:
When dividing 1 by 28, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 28

Advancing to step 2:
When dividing 14 by 28, we get 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 28

On to step 3:
When dividing 140 by 28, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 0 after subtracting 140 from 140.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 28

Advancing to step 4:
If we divide 1 by 28, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 50.0
If we take 0 away from 1, we end up with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 28

Step 5:
The number 28 fits into 14 0 times, leaving a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 500.0
Deduct 0 from 14 and we're left with 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 28

Let's proceed to step 6:
The number 28 fits into 145 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 5005.0
If we subtract 140 from 145, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
If we divide 50 by 28, we get 1 and a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 5005.1
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.
Record the quotient 7 as the next digit in the result. 
Result so far: 5005.17
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.

Moving on to step 9:
If we divide 240 by 28, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 5005.178
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.

Advancing 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: 5005.1785
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.

Advancing to step 11:
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: 5005.17857
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.

Let's proceed to step 12:
40 divided by 28 is 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 5005.178571
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.

Going ahead to step 13:
28 goes into 120 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 5005.1785714
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.

On to step 14:
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: 5005.17857142
If we take 56 away from 80, 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.

The quotient of the division is 5005.17857142, and the remainder is 2.4e-08.
