We look at the division of 284640 by 31 
We're looking to find how many times 31 goes into 284640.

Moving on to step 1:
31 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 31

Going ahead to step 2:
28 divided by 31 is 0 with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Take the next digit (4) from the dividend and append it to 28, then repeat: 284 / 31

Step 3:
31 goes into 284 9 times with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 279 from 284 to get 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 31

Let's proceed to step 4:
31 can be fit into 56 1 times, resulting in a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 91.0
Deduct 31 from 56 and we're left with 25.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 31

Step 5:
254 divided by 31 is 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 918.0
Deduct 248 from 254 and we're left with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 31

Step 6:
If we divide 60 by 31, we get 1 and a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 9181.0
The remainder is 29 after subtracting 31 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
When dividing 290 by 31, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 9181.9
Subtracting 279 from 290 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 8:
If we divide 110 by 31, we get 3 and a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 9181.93
Deduct 93 from 110 and we're left 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.

Step 9:
31 goes into 170 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 9181.935
If we take 155 away from 170, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
31 goes into 150 4 times with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 9181.9354
The remainder is 26 after subtracting 124 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 11:
The number 31 fits into 260 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 9181.93548
Deduct 248 from 260 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
If we divide 120 by 31, we get 3 and a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 9181.935483
The remainder is 27 after subtracting 93 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 13:
The number 31 fits into 270 8 times, leaving a remainder of 22.
The next digit of our result is 8. 
Result so far: 9181.9354838
Deduct 248 from 270 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 14:
The number 31 fits into 220 7 times, leaving a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 9181.93548387
The remainder is 3 after subtracting 217 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 9181.93548387 and a remainder of 3e-09.
