We divide 285217 by 31
We're looking to find how many times 31 goes into 285217.

Advancing to step 1:
31 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 31

Advancing to step 2:
The number 31 fits into 28 0 times, leaving a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 31

Let's proceed to step 3:
31 can be fit into 285 9 times, resulting in a remainder of 6.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 279 from 285 and we're left with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 31

Advancing to step 4:
62 divided by 31 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 92.0
Subtract 62 from 62 to get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 31

Going ahead to step 5:
31 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 920.0
If we take 0 away from 1, we end up with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 31

Let's proceed to step 6:
31 goes into 17 0 times with a remainder of 17.
The next digit of our result is 0. 
Result so far: 9200.0
If we subtract 0 from 17, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
31 can be fit into 170 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 9200.5
If we subtract 155 from 170, we get 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 8:
31 can be fit into 150 4 times, resulting in a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 9200.54
If we subtract 124 from 150, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 9:
The number 31 fits into 260 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 9200.548
If we take 248 away from 260, we end up 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 10:
31 can be fit into 120 3 times, resulting in a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 9200.5483
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 11:
31 goes into 270 8 times with a remainder of 22.
The next digit of our result is 8. 
Result so far: 9200.54838
If we subtract 248 from 270, we get 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 12:
31 goes into 220 7 times with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 9200.548387
If we take 217 away from 220, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 13:
31 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 9200.548387
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
If we divide 300 by 31, we get 9 and a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 9200.54838709
If we take 279 away from 300, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

In conclusion, the division gives 9200.54838709 with a balance of 2.1e-08.
