We're dividing 313823 by 87 
Let's see how many times 87 fits into 313823.

Step 1:
87 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 87

Moving on to step 2:
31 divided by 87 is 0 with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 87

Going ahead to step 3:
When dividing 313 by 87, we get 3 with a remainder of 52.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 261 from 313, we get 52.
Bring next digit (8) of the dividend behind the 52 and repeat the process: 528 / 87

Step 4:
87 can be fit into 528 6 times, resulting in a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
Deduct 522 from 528 and we're left with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 87

Advancing to step 5:
87 can be fit into 62 0 times, resulting in a remainder of 62.
Write down 0 as next digit of the result. 
Result so far: 360.0
Deduct 0 from 62 and we're left with 62.
Bring next digit (3) of the dividend behind the 62 and repeat the process: 623 / 87

Moving on to step 6:
If we divide 623 by 87, we get 7 and a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 3607.0
Deduct 609 from 623 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
140 divided by 87 is 1 with a remainder of 53.
The next digit of our result is 1. 
Result so far: 3607.1
If we take 87 away from 140, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 8:
87 can be fit into 530 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 3607.16
Subtract 522 from 530 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
When dividing 80 by 87, we get 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 3607.16
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 10:
87 goes into 800 9 times with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 3607.1609
If we take 783 away from 800, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 11:
87 goes into 170 1 times with a remainder of 83.
Write down 1 as next digit of the result. 
Result so far: 3607.16091
Subtract 87 from 170 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 12:
The number 87 fits into 830 9 times, leaving a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 3607.160919
If we subtract 783 from 830, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 13:
87 can be fit into 470 5 times, resulting in a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 3607.1609195
If we take 435 away from 470, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 14:
87 goes into 350 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 3607.16091954
Deduct 348 from 350 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 3607.16091954 and a remainder of 2e-09.
