We look at the division of 28815447 by 173 
Let's see how many times 173 fits into 28815447.

Going ahead to step 1:
173 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 173

Step 2:
The number 173 fits into 28 0 times, leaving a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 173

Moving on to step 3:
173 can be fit into 288 1 times, resulting in a remainder of 115.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 173 from 288 and we're left with 115.
Bring next digit (1) of the dividend behind the 115 and repeat the process: 1151 / 173

Advancing to step 4:
173 can be fit into 1151 6 times, resulting in a remainder of 113.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 113 after subtracting 1038 from 1151.
Include the next digit (5) from the dividend after 113, then repeat: 1135 / 173

Going ahead to step 5:
1135 divided by 173 is 6 with a remainder of 97.
Write down 6 as next digit of the result. 
Result so far: 166.0
If we take 1038 away from 1135, we end up with 97.
Take the next digit (4) from the dividend and append it to 97, then repeat: 974 / 173

Going ahead to step 6:
173 goes into 974 5 times with a remainder of 109.
Write down 5 as next digit of the result. 
Result so far: 1665.0
The remainder is 109 after subtracting 865 from 974.
Append the next digit (4) from the dividend to 109 and continue with: 1094 / 173

Going ahead to step 7:
1094 divided by 173 is 6 with a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 16656.0
Subtracting 1038 from 1094 leaves us with 56.
Include the next digit (7) from the dividend after 56, then repeat: 567 / 173

Going ahead to step 8:
The number 173 fits into 567 3 times, leaving a remainder of 48.
The next digit of our result is 3. 
Result so far: 166563.0
Deduct 519 from 567 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 9:
If we divide 480 by 173, we get 2 and a remainder of 134.
Record the quotient 2 as the next digit in the result. 
Result so far: 166563.2
The remainder is 134 after subtracting 346 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 10:
When dividing 1340 by 173, we get 7 with a remainder of 129.
Write down 7 as next digit of the result. 
Result so far: 166563.27
If we subtract 1211 from 1340, we get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Let's proceed to step 11:
173 can be fit into 1290 7 times, resulting in a remainder of 79.
Write down 7 as next digit of the result. 
Result so far: 166563.277
Subtract 1211 from 1290 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Our division results in 166563.277 with a remaining 0.0079.
