We look at the division of 175209 by 87 
We want to divide 175209 by 87.

Moving on to step 1:
1 divided by 87 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 87

Moving on to step 2:
17 divided by 87 is 0 with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 87

Going ahead to step 3:
87 can be fit into 175 2 times, resulting in a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 174 from 175, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 87

Moving on to step 4:
12 divided by 87 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 12 to get 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 87

Step 5:
87 can be fit into 120 1 times, resulting in a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 201.0
If we take 87 away from 120, we end up with 33.
Grab the next digit (9) from the dividend, add it to 33, then carry on: 339 / 87

Step 6:
87 can be fit into 339 3 times, resulting in a remainder of 78.
Write down 3 as next digit of the result. 
Result so far: 2013.0
Deduct 261 from 339 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 7:
When dividing 780 by 87, we get 8 with a remainder of 84.
Write down 8 as next digit of the result. 
Result so far: 2013.8
Subtract 696 from 780 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 8:
87 can be fit into 840 9 times, resulting in a remainder of 57.
Record the quotient 9 as the next digit in the result. 
Result so far: 2013.89
The remainder is 57 after subtracting 783 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 9:
87 can be fit into 570 6 times, resulting in a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 2013.896
Subtracting 522 from 570 leaves us 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.

Let's proceed to step 10:
The number 87 fits into 480 5 times, leaving a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 2013.8965
Deduct 435 from 480 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 11:
When dividing 450 by 87, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 2013.89655
If we subtract 435 from 450, 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.

After the division, we end up with 2013.89655 and a remainder of 1.5e-05.
