We look at the division of 131230 by 87 
Let's see how many times 87 fits into 131230.

Moving on to step 1:
If we divide 1 by 87, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 87

Advancing to step 2:
13 divided by 87 is 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 87

On to step 3:
If we divide 131 by 87, we get 1 and a remainder of 44.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 87 from 131 to get 44.
Take the next digit (2) from the dividend and append it to 44, then repeat: 442 / 87

Let's proceed to step 4:
442 divided by 87 is 5 with a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 7 after subtracting 435 from 442.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 87

Advancing to step 5:
73 divided by 87 is 0 with a remainder of 73.
The next digit of our result is 0. 
Result so far: 150.0
Subtract 0 from 73 to get 73.
Append the next digit (0) from the dividend to 73 and continue with: 730 / 87

On to step 6:
730 divided by 87 is 8 with a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 1508.0
Deduct 696 from 730 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 7:
The number 87 fits into 340 3 times, leaving a remainder of 79.
Use 3 as the next digit of our solution. 
Result so far: 1508.3
Subtracting 261 from 340 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 8:
87 can be fit into 790 9 times, resulting in a remainder of 7.
The next digit of our result is 9. 
Result so far: 1508.39
Subtract 783 from 790 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
The number 87 fits into 70 0 times, leaving a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 1508.39
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
87 can be fit into 700 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 1508.3908
The remainder is 4 after subtracting 696 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
40 divided by 87 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 1508.3908
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
When dividing 400 by 87, we get 4 with a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 1508.390804
The remainder is 52 after subtracting 348 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 13:
When dividing 520 by 87, we get 5 with a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 1508.3908045
Subtract 435 from 520 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 14:
87 goes into 850 9 times with a remainder of 67.
The number 9 becomes the next digit in our result. 
Result so far: 1508.39080459
If we take 783 away from 850, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

The final outcome is 1508.39080459, with a leftover of 6.7e-08.
