166559 divided by 28 
Let's see how many times 28 fits into 166559.

Step 1:
1 divided by 28 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 28

Moving on to step 2:
16 divided by 28 is 0 with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 28

Step 3:
166 divided by 28 is 5 with a remainder of 26.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 140 from 166 leaves us with 26.
Grab the next digit (5) from the dividend, add it to 26, then carry on: 265 / 28

Let's proceed to step 4:
265 divided by 28 is 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 59.0
Subtracting 252 from 265 leaves us with 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 28

Step 5:
When dividing 135 by 28, we get 4 with a remainder of 23.
Record the quotient 4 as the next digit in the result. 
Result so far: 594.0
Deduct 112 from 135 and we're left with 23.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 28

Step 6:
When dividing 239 by 28, we get 8 with a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 5948.0
If we subtract 224 from 239, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
If we divide 150 by 28, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 5948.5
The remainder is 10 after subtracting 140 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
The number 28 fits into 100 3 times, leaving a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 5948.53
Subtract 84 from 100 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 9:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 5948.535
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.

Going ahead to step 10:
If we divide 200 by 28, we get 7 and a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 5948.5357
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 can be fit into 40 1 times, resulting in a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 5948.53571
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.

Moving on to step 12:
If we divide 120 by 28, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 5948.535714
Subtracting 112 from 120 leaves us 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.

Moving on to step 13:
28 goes into 80 2 times with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 5948.5357142
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
If we divide 240 by 28, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 5948.53571428
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.

The final result is 5948.53571428 with a remainder of 1.6e-08.
