We're dividing 150513 by 87 
Our goal is to divide 150513 by 87.

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
If we subtract 0 from 1, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 87

Let's proceed to step 2:
87 goes into 15 0 times with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 87

Going ahead to step 3:
87 can be fit into 150 1 times, resulting in a remainder of 63.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 87 away from 150, we end up with 63.
Grab the next digit (5) from the dividend, add it to 63, then carry on: 635 / 87

Moving on to step 4:
87 goes into 635 7 times with a remainder of 26.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 609 from 635 and we're left with 26.
Include the next digit (1) from the dividend after 26, then repeat: 261 / 87

Moving on to step 5:
87 can be fit into 261 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 173.0
If we subtract 261 from 261, we get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 87

Advancing to step 6:
When dividing 3 by 87, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 1730.0
The remainder is 3 after subtracting 0 from 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
The number 87 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 1730.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
If we divide 300 by 87, we get 3 and a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 1730.03
Subtract 261 from 300 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 9:
When dividing 390 by 87, we get 4 with a remainder of 42.
The next digit of our result is 4. 
Result so far: 1730.034
Subtracting 348 from 390 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 10:
87 can be fit into 420 4 times, resulting in a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 1730.0344
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 quotient of the division is 1730.0344, and the remainder is 0.00072.
