Let's divide 28399823 by 173
We're looking to find how many times 173 goes into 28399823.

Moving on 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
Deduct 0 from 2 and we're left with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 173

Going ahead to step 2:
If we divide 28 by 173, we get 0 and a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Grab the next digit (3) from the dividend, add it to 28, then carry on: 283 / 173

Step 3:
283 divided by 173 is 1 with a remainder of 110.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 173 away from 283, we end up with 110.
Grab the next digit (9) from the dividend, add it to 110, then carry on: 1109 / 173

Moving on to step 4:
1109 divided by 173 is 6 with a remainder of 71.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 1038 from 1109, we get 71.
Fetch the next digit (9) from the dividend, attach it to 71 and continue: 719 / 173

Step 5:
The number 173 fits into 719 4 times, leaving a remainder of 27.
Use 4 as the next digit of our solution. 
Result so far: 164.0
If we subtract 692 from 719, we get 27.
Take the next digit (8) from the dividend and append it to 27, then repeat: 278 / 173

On to step 6:
173 goes into 278 1 times with a remainder of 105.
Use 1 as the next digit of our solution. 
Result so far: 1641.0
Subtract 173 from 278 to get 105.
Include the next digit (2) from the dividend after 105, then repeat: 1052 / 173

Step 7:
173 can be fit into 1052 6 times, resulting in a remainder of 14.
The next digit of our result is 6. 
Result so far: 16416.0
Deduct 1038 from 1052 and we're left with 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 173

Let's proceed to step 8:
143 divided by 173 is 0 with a remainder of 143.
Use 0 as the next digit of our solution. 
Result so far: 164160.0
The remainder is 143 after subtracting 0 from 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Moving on to step 9:
The number 173 fits into 1430 8 times, leaving a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 164160.8
Subtract 1384 from 1430 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 10:
460 divided by 173 is 2 with a remainder of 114.
Put 2 as the next digit of the answer. 
Result so far: 164160.82
Deduct 346 from 460 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 11:
The number 173 fits into 1140 6 times, leaving a remainder of 102.
Use 6 as the next digit of our solution. 
Result so far: 164160.826
Deduct 1038 from 1140 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Going ahead to step 12:
173 can be fit into 1020 5 times, resulting in a remainder of 155.
The next digit of our result is 5. 
Result so far: 164160.8265
If we subtract 865 from 1020, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 13:
173 can be fit into 1550 8 times, resulting in a remainder of 166.
Record the quotient 8 as the next digit in the result. 
Result so far: 164160.82658
Subtract 1384 from 1550 to get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Advancing to step 14:
If we divide 1660 by 173, we get 9 and a remainder of 103.
The next digit of our result is 9. 
Result so far: 164160.826589
Subtract 1557 from 1660 to get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Step 15:
1030 divided by 173 is 5 with a remainder of 165.
Put 5 as the next digit of the answer. 
Result so far: 164160.8265895
If we take 865 away from 1030, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 16:
The number 173 fits into 1650 9 times, leaving a remainder of 93.
Put 9 as the next digit of the answer. 
Result so far: 164160.82658959
The remainder is 93 after subtracting 1557 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

The final outcome is 164160.82658959, with a leftover of 9.3e-08.
