Let's divide 172569 by 87
Let's see how many times 87 fits into 172569.

Moving on to step 1:
The number 87 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 87

Step 2:
87 can be fit into 17 0 times, resulting in a remainder of 17.
Put 0 as the next digit of the answer. 
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

On to step 3:
87 can be fit into 172 1 times, resulting in a remainder of 85.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 85 after subtracting 87 from 172.
Bring next digit (5) of the dividend behind the 85 and repeat the process: 855 / 87

Advancing to step 4:
87 can be fit into 855 9 times, resulting in a remainder of 72.
The next digit of our result is 9. 
Result so far: 19.0
If we subtract 783 from 855, we get 72.
Append the next digit (6) from the dividend to 72 and continue with: 726 / 87

On to step 5:
When dividing 726 by 87, we get 8 with a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 198.0
Subtracting 696 from 726 leaves us with 30.
Fetch the next digit (9) from the dividend, attach it to 30 and continue: 309 / 87

Moving on to step 6:
When dividing 309 by 87, we get 3 with a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 1983.0
Subtract 261 from 309 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 7:
When dividing 480 by 87, we get 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 1983.5
Subtract 435 from 480 to get 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 8:
450 divided by 87 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 1983.55
The remainder is 15 after subtracting 435 from 450.
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 1983.55 and a remainder of 0.015.
