171840 divided by 28 
Our goal is to divide 171840 by 28.

Going ahead to step 1:
The number 28 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 28

Let's proceed to step 2:
28 goes into 17 0 times with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 28

Moving on to step 3:
If we divide 171 by 28, we get 6 and a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 168 from 171 leaves us with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 28

Advancing to step 4:
38 divided by 28 is 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 61.0
Subtract 28 from 38 to get 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 28

Going ahead to step 5:
28 can be fit into 104 3 times, resulting in a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 613.0
If we subtract 84 from 104, we get 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 28

Step 6:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 6137.0
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.

On to step 7:
40 divided by 28 is 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 6137.1
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.

Moving on to step 8:
120 divided by 28 is 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 6137.14
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.

Going ahead to step 9:
80 divided by 28 is 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 6137.142
Subtracting 56 from 80 leaves us 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 10:
When dividing 240 by 28, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 6137.1428
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.

Going ahead to step 11:
28 can be fit into 160 5 times, resulting in a remainder of 20.
The next digit of our result is 5. 
Result so far: 6137.14285
If we take 140 away from 160, we end up 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 12:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 6137.142857
The remainder is 4 after subtracting 196 from 200.
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 13:
28 goes into 40 1 times with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 6137.1428571
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.

Step 14:
28 can be fit into 120 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 6137.14285714
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.

The quotient of the division is 6137.14285714, and the remainder is 8e-09.
