We're dividing 172768 by 87 
We want to figure out the number of times 172768 can be divided by 87.

Moving on to step 1:
When dividing 1 by 87, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 87

On to step 2:
The number 87 fits into 17 0 times, leaving a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 87

Let's proceed to step 3:
87 goes into 172 1 times with a remainder of 85.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 87 from 172 leaves us with 85.
Bring next digit (7) of the dividend behind the 85 and repeat the process: 857 / 87

On to step 4:
857 divided by 87 is 9 with a remainder of 74.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtract 783 from 857 to get 74.
Include the next digit (6) from the dividend after 74, then repeat: 746 / 87

Moving on to step 5:
If we divide 746 by 87, we get 8 and a remainder of 50.
Record the quotient 8 as the next digit in the result. 
Result so far: 198.0
If we subtract 696 from 746, we get 50.
Take the next digit (8) from the dividend and append it to 50, then repeat: 508 / 87

Going ahead to step 6:
If we divide 508 by 87, we get 5 and a remainder of 73.
The next digit of our result is 5. 
Result so far: 1985.0
If we subtract 435 from 508, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 7:
730 divided by 87 is 8 with a remainder of 34.
The next digit of our result is 8. 
Result so far: 1985.8
If we take 696 away from 730, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
If we divide 340 by 87, we get 3 and a remainder of 79.
Use 3 as the next digit of our solution. 
Result so far: 1985.83
Deduct 261 from 340 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 9:
The number 87 fits into 790 9 times, leaving a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 1985.839
Subtracting 783 from 790 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 10:
87 can be fit into 70 0 times, resulting in a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 1985.839
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 11:
700 divided by 87 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 1985.83908
Subtracting 696 from 700 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.

On to step 12:
If we divide 40 by 87, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 1985.83908
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
When dividing 400 by 87, we get 4 with a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 1985.8390804
Subtract 348 from 400 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 14:
If we divide 520 by 87, we get 5 and a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 1985.83908045
The remainder is 85 after subtracting 435 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

After the division, we end up with 1985.83908045 and a remainder of 8.5e-08.
