585480 ÷ 31 
Our goal is to divide 585480 by 31.

Going ahead to step 1:
When dividing 5 by 31, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 31

On to step 2:
58 divided by 31 is 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 1.0
If we take 31 away from 58, we end up with 27.
Bring next digit (5) of the dividend behind the 27 and repeat the process: 275 / 31

Advancing to step 3:
The number 31 fits into 275 8 times, leaving a remainder of 27.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 27 after subtracting 248 from 275.
Include the next digit (4) from the dividend after 27, then repeat: 274 / 31

Let's proceed to step 4:
If we divide 274 by 31, we get 8 and a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 188.0
If we subtract 248 from 274, we get 26.
Fetch the next digit (8) from the dividend, attach it to 26 and continue: 268 / 31

On to step 5:
The number 31 fits into 268 8 times, leaving a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 1888.0
Subtracting 248 from 268 leaves us with 20.
Include the next digit (0) from the dividend after 20, then repeat: 200 / 31

Step 6:
31 can be fit into 200 6 times, resulting in a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 18886.0
The remainder is 14 after subtracting 186 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
The number 31 fits into 140 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 18886.4
If we take 124 away from 140, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
31 can be fit into 160 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 18886.45
If we take 155 away from 160, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
31 can be fit into 50 1 times, resulting in a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 18886.451
If we subtract 31 from 50, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 10:
If we divide 190 by 31, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 18886.4516
The remainder is 4 after subtracting 186 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
The number 31 fits into 40 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 18886.45161
If we take 31 away from 40, we end up 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.

Moving on to step 12:
90 divided by 31 is 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 18886.451612
Subtract 62 from 90 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 13:
The number 31 fits into 280 9 times, leaving a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 18886.4516129
Deduct 279 from 280 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 14:
If we divide 10 by 31, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 18886.4516129
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 18886.4516129 with a remaining 1e-08.
