Let's divide 31005 by 87
We're looking to find how many times 87 goes into 31005.

Let's proceed to step 1:
87 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 87

Step 2:
If we divide 31 by 87, we get 0 and a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 87

Moving on to step 3:
When dividing 310 by 87, we get 3 with a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 261 from 310 to get 49.
Fetch the next digit (0) from the dividend, attach it to 49 and continue: 490 / 87

On to step 4:
If we divide 490 by 87, we get 5 and a remainder of 55.
The next digit of our result is 5. 
Result so far: 35.0
Subtract 435 from 490 to get 55.
Take the next digit (5) from the dividend and append it to 55, then repeat: 555 / 87

On to step 5:
555 divided by 87 is 6 with a remainder of 33.
Record the quotient 6 as the next digit in the result. 
Result so far: 356.0
If we subtract 522 from 555, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 6:
87 can be fit into 330 3 times, resulting in a remainder of 69.
The number 3 becomes the next digit in our result. 
Result so far: 356.3
If we subtract 261 from 330, we get 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:
The number 87 fits into 690 7 times, leaving a remainder of 81.
The next digit of our result is 7. 
Result so far: 356.37
Deduct 609 from 690 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 8:
87 can be fit into 810 9 times, resulting in a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 356.379
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.

Step 9:
87 can be fit into 270 3 times, resulting in a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 356.3793
Subtracting 261 from 270 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 10:
87 goes into 90 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 356.37931
If we subtract 87 from 90, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 11:
The number 87 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 356.37931
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
87 can be fit into 300 3 times, resulting in a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 356.3793103
If we take 261 away from 300, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 13:
390 divided by 87 is 4 with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 356.37931034
If we take 348 away from 390, we end up 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.

The quotient of the division is 356.37931034, and the remainder is 4.2e-08.
