We're dividing 131729 by 87 
We want to figure out the number of times 131729 can be divided by 87.

Advancing to step 1:
87 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 87

Going ahead to step 2:
The number 87 fits into 13 0 times, leaving a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 87

Advancing to step 3:
131 divided by 87 is 1 with a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 87 from 131, we get 44.
Append the next digit (7) from the dividend to 44 and continue with: 447 / 87

Let's proceed to step 4:
447 divided by 87 is 5 with a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 435 from 447 leaves us with 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 87

Going ahead to step 5:
If we divide 122 by 87, we get 1 and a remainder of 35.
The next digit of our result is 1. 
Result so far: 151.0
The remainder is 35 after subtracting 87 from 122.
Grab the next digit (9) from the dividend, add it to 35, then carry on: 359 / 87

Moving on to step 6:
87 goes into 359 4 times with a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 1514.0
The remainder is 11 after subtracting 348 from 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
87 can be fit into 110 1 times, resulting in a remainder of 23.
The next digit of our result is 1. 
Result so far: 1514.1
The remainder is 23 after subtracting 87 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 8:
87 goes into 230 2 times with a remainder of 56.
The next digit of our result is 2. 
Result so far: 1514.12
The remainder is 56 after subtracting 174 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
87 goes into 560 6 times with a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 1514.126
If we subtract 522 from 560, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 10:
87 goes into 380 4 times with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 1514.1264
If we subtract 348 from 380, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
When dividing 320 by 87, we get 3 with a remainder of 59.
The next digit of our result is 3. 
Result so far: 1514.12643
If we take 261 away from 320, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 12:
If we divide 590 by 87, we get 6 and a remainder of 68.
The number 6 becomes the next digit in our result. 
Result so far: 1514.126436
If we subtract 522 from 590, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 13:
680 divided by 87 is 7 with a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 1514.1264367
Deduct 609 from 680 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 14:
The number 87 fits into 710 8 times, leaving a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 1514.12643678
Subtract 696 from 710 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 1514.12643678 with a balance of 1.4e-08.
