We're dividing 310855 by 87 
We want to divide 310855 by 87.

Advancing to step 1:
87 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 87

Advancing to step 2:
When dividing 31 by 87, we get 0 with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Take the next digit (0) from the dividend and append it to 31, then repeat: 310 / 87

Advancing to step 3:
310 divided by 87 is 3 with a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 261 away from 310, we end up with 49.
Include the next digit (8) from the dividend after 49, then repeat: 498 / 87

Moving on to step 4:
The number 87 fits into 498 5 times, leaving a remainder of 63.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Subtract 435 from 498 to get 63.
Include the next digit (5) from the dividend after 63, then repeat: 635 / 87

Step 5:
87 goes into 635 7 times with a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 357.0
If we take 609 away from 635, we end up with 26.
Grab the next digit (5) from the dividend, add it to 26, then carry on: 265 / 87

Advancing to step 6:
When dividing 265 by 87, we get 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 3573.0
Deduct 261 from 265 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
40 divided by 87 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 3573.0
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 8:
87 goes into 400 4 times with a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 3573.04
Subtract 348 from 400 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 9:
If we divide 520 by 87, we get 5 and a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 3573.045
If we take 435 away from 520, we end up with 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 10:
When dividing 850 by 87, we get 9 with a remainder of 67.
Put 9 as the next digit of the answer. 
Result so far: 3573.0459
Subtracting 783 from 850 leaves us 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.

Going ahead to step 11:
87 goes into 670 7 times with a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 3573.04597
If we subtract 609 from 670, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 12:
610 divided by 87 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 3573.045977
Subtract 609 from 610 to get 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 quotient of the division is 3573.045977, and the remainder is 1e-07.
