131503 ÷ 87 
We're looking to find how many times 87 goes into 131503.

Advancing to step 1:
If we divide 1 by 87, we get 0 and 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.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 87

Advancing to step 2:
13 divided by 87 is 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 87

Step 3:
If we divide 131 by 87, we get 1 and a remainder of 44.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 44 after subtracting 87 from 131.
Bring next digit (5) of the dividend behind the 44 and repeat the process: 445 / 87

Let's proceed to step 4:
87 can be fit into 445 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 435 away from 445, we end up with 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 87

Moving on to step 5:
100 divided by 87 is 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 151.0
If we subtract 87 from 100, we get 13.
Fetch the next digit (3) from the dividend, attach it to 13 and continue: 133 / 87

Moving on to step 6:
When dividing 133 by 87, we get 1 with a remainder of 46.
Write down 1 as next digit of the result. 
Result so far: 1511.0
Deduct 87 from 133 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 7:
When dividing 460 by 87, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 1511.5
Subtract 435 from 460 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 8:
If we divide 250 by 87, we get 2 and a remainder of 76.
The number 2 becomes the next digit in our result. 
Result so far: 1511.52
Subtracting 174 from 250 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 9:
87 goes into 760 8 times with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 1511.528
If we subtract 696 from 760, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 10:
87 can be fit into 640 7 times, resulting in a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 1511.5287
Subtract 609 from 640 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 11:
87 goes into 310 3 times with a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 1511.52873
If we subtract 261 from 310, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 12:
490 divided by 87 is 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 1511.528735
Subtracting 435 from 490 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 13:
87 can be fit into 550 6 times, resulting in a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 1511.5287356
Subtracting 522 from 550 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 14:
If we divide 280 by 87, we get 3 and a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 1511.52873563
Subtract 261 from 280 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final result is 1511.52873563 with a remainder of 1.9e-08.
