Let's divide 143880 by 87
We want to figure out the number of times 143880 can be divided by 87.

Moving on to step 1:
1 divided by 87 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 87

Step 2:
14 divided by 87 is 0 with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 87

Let's proceed to step 3:
If we divide 143 by 87, we get 1 and a remainder of 56.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 87 from 143 leaves us with 56.
Bring next digit (8) of the dividend behind the 56 and repeat the process: 568 / 87

Step 4:
87 goes into 568 6 times with a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtract 522 from 568 to get 46.
Grab the next digit (8) from the dividend, add it to 46, then carry on: 468 / 87

Let's proceed to step 5:
87 goes into 468 5 times with a remainder of 33.
Use 5 as the next digit of our solution. 
Result so far: 165.0
If we subtract 435 from 468, we get 33.
Include the next digit (0) from the dividend after 33, then repeat: 330 / 87

Moving on to step 6:
The number 87 fits into 330 3 times, leaving a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 1653.0
Subtracting 261 from 330 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 7:
87 goes into 690 7 times with a remainder of 81.
Record the quotient 7 as the next digit in the result. 
Result so far: 1653.7
Subtract 609 from 690 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 8:
The number 87 fits into 810 9 times, leaving a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 1653.79
Subtracting 783 from 810 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 9:
The number 87 fits into 270 3 times, leaving a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 1653.793
If we subtract 261 from 270, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 10:
87 goes into 90 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1653.7931
If we take 87 away from 90, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 11:
The number 87 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 1653.7931
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 12:
87 goes into 300 3 times with a remainder of 39.
The next digit of our result is 3. 
Result so far: 1653.793103
The remainder is 39 after subtracting 261 from 300.
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 13:
When dividing 390 by 87, we get 4 with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 1653.7931034
Deduct 348 from 390 and we're left 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.

Step 14:
87 can be fit into 420 4 times, resulting in a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 1653.79310344
If we subtract 348 from 420, we 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.

Our division results in 1653.79310344 with a remaining 7.2e-08.
