We're dividing 103080 by 87 
We want to divide 103080 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 take 0 away from 1, we end up with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 87

Moving on to step 2:
The number 87 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 87

Moving on to step 3:
If we divide 103 by 87, we get 1 and a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 16 after subtracting 87 from 103.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 87

Step 4:
87 can be fit into 160 1 times, resulting in a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 73 after subtracting 87 from 160.
Grab the next digit (8) from the dividend, add it to 73, then carry on: 738 / 87

On to step 5:
87 goes into 738 8 times with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
The remainder is 42 after subtracting 696 from 738.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 87

Let's proceed to step 6:
If we divide 420 by 87, we get 4 and a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 1184.0
If we take 348 away from 420, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 7:
87 can be fit into 720 8 times, resulting in a remainder of 24.
The next digit of our result is 8. 
Result so far: 1184.8
Deduct 696 from 720 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
87 can be fit into 240 2 times, resulting in a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 1184.82
If we subtract 174 from 240, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 9:
87 can be fit into 660 7 times, resulting in a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 1184.827
If we take 609 away from 660, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 10:
510 divided by 87 is 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 1184.8275
The remainder is 75 after subtracting 435 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 11:
87 goes into 750 8 times with a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 1184.82758
Subtracting 696 from 750 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 12:
87 goes into 540 6 times with a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 1184.827586
If we take 522 away from 540, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
87 goes into 180 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 1184.8275862
The remainder is 6 after subtracting 174 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 14:
The number 87 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 1184.8275862
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 1184.8275862 with a remainder of 6e-08.
