We divide 313513 by 87
Our goal is to divide 313513 by 87.

On to step 1:
When dividing 3 by 87, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 87

Going ahead to step 2:
When dividing 31 by 87, we get 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Fetch the next digit (3) from the dividend, attach it to 31 and continue: 313 / 87

Advancing to step 3:
87 can be fit into 313 3 times, resulting in a remainder of 52.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 52 after subtracting 261 from 313.
Take the next digit (5) from the dividend and append it to 52, then repeat: 525 / 87

Moving on to step 4:
525 divided by 87 is 6 with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 36.0
The remainder is 3 after subtracting 522 from 525.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 87

Moving on to step 5:
When dividing 31 by 87, we get 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 360.0
Subtract 0 from 31 to get 31.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 87

Going ahead to step 6:
87 goes into 313 3 times with a remainder of 52.
Write down 3 as next digit of the result. 
Result so far: 3603.0
Subtract 261 from 313 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.

On to step 7:
The number 87 fits into 520 5 times, leaving a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 3603.5
Subtracting 435 from 520 leaves us 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 8:
850 divided by 87 is 9 with a remainder of 67.
The next digit of our result is 9. 
Result so far: 3603.59
Subtract 783 from 850 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 9:
If we divide 670 by 87, we get 7 and a remainder of 61.
Write down 7 as next digit of the result. 
Result so far: 3603.597
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.

Let's proceed to step 10:
87 goes into 610 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 3603.5977
If we subtract 609 from 610, we 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.

After the division, we end up with 3603.5977 and a remainder of 1e-05.
