We divide 31480 by 87
We're looking to find how many times 87 goes into 31480.

On to step 1:
If we divide 3 by 87, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
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

Advancing to step 2:
When dividing 31 by 87, we get 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Include the next digit (4) from the dividend after 31, then repeat: 314 / 87

Moving on to step 3:
When dividing 314 by 87, we get 3 with a remainder of 53.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 261 away from 314, we end up with 53.
Include the next digit (8) from the dividend after 53, then repeat: 538 / 87

Moving on to step 4:
87 can be fit into 538 6 times, resulting in a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 36.0
If we subtract 522 from 538, we get 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 87

Going ahead to step 5:
The number 87 fits into 160 1 times, leaving a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 361.0
The remainder is 73 after subtracting 87 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 6:
When dividing 730 by 87, we get 8 with a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 361.8
Subtract 696 from 730 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
340 divided by 87 is 3 with a remainder of 79.
Write down 3 as next digit of the result. 
Result so far: 361.83
Deduct 261 from 340 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 8:
87 goes into 790 9 times with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 361.839
The remainder is 7 after subtracting 783 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
87 can be fit into 70 0 times, resulting in a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 361.839
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 10:
The number 87 fits into 700 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 361.83908
The remainder is 4 after subtracting 696 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
The number 87 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 361.83908
If we take 0 away from 40, we end up 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 12:
When dividing 400 by 87, we get 4 with a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 361.8390804
Subtracting 348 from 400 leaves us with 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 13:
When dividing 520 by 87, we get 5 with a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 361.83908045
Deduct 435 from 520 and we're left 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.

The final outcome is 361.83908045, with a leftover of 8.5e-08.
