We're dividing 165303 by 87 
We're looking to find how many times 87 goes into 165303.

On to step 1:
When dividing 1 by 87, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 87

Moving on to step 2:
87 goes into 16 0 times with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 87

Going ahead to step 3:
The number 87 fits into 165 1 times, leaving a remainder of 78.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 87 away from 165, we end up with 78.
Fetch the next digit (3) from the dividend, attach it to 78 and continue: 783 / 87

On to step 4:
87 can be fit into 783 9 times, resulting in a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 19.0
Deduct 783 from 783 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 87

Let's proceed to step 5:
When dividing 0 by 87, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 190.0
If we take 0 away from 0, we end up with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 87

Going ahead to step 6:
3 divided by 87 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 1900.0
If we subtract 0 from 3, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
87 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 1900.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
87 goes into 300 3 times with a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 1900.03
If we take 261 away from 300, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 9:
The number 87 fits into 390 4 times, leaving a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 1900.034
Subtract 348 from 390 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 10:
87 goes into 420 4 times with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 1900.0344
Subtract 348 from 420 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 1900.0344, with a leftover of 0.00072.
