143983 ÷ 87 
We want to divide 143983 by 87.

Going ahead to step 1:
87 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 87

Advancing to step 2:
14 divided by 87 is 0 with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 87

On to step 3:
The number 87 fits into 143 1 times, leaving a remainder of 56.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 87 from 143 leaves us with 56.
Grab the next digit (9) from the dividend, add it to 56, then carry on: 569 / 87

Step 4:
569 divided by 87 is 6 with a remainder of 47.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 47 after subtracting 522 from 569.
Include the next digit (8) from the dividend after 47, then repeat: 478 / 87

On to step 5:
478 divided by 87 is 5 with a remainder of 43.
Put 5 as the next digit of the answer. 
Result so far: 165.0
If we take 435 away from 478, we end up with 43.
Fetch the next digit (3) from the dividend, attach it to 43 and continue: 433 / 87

Going ahead to step 6:
If we divide 433 by 87, we get 4 and a remainder of 85.
Record the quotient 4 as the next digit in the result. 
Result so far: 1654.0
If we subtract 348 from 433, we 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.

Step 7:
The number 87 fits into 850 9 times, leaving a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 1654.9
The remainder is 67 after subtracting 783 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 8:
The number 87 fits into 670 7 times, leaving a remainder of 61.
Write down 7 as next digit of the result. 
Result so far: 1654.97
The remainder is 61 after subtracting 609 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 9:
The number 87 fits into 610 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 1654.977
Deduct 609 from 610 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 1654.977, with a leftover of 0.0001.
