285329 divided by 31 
We want to divide 285329 by 31.

Going ahead to step 1:
The number 31 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 31

Step 2:
If we divide 28 by 31, we get 0 and a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Bring next digit (5) of the dividend behind the 28 and repeat the process: 285 / 31

On to step 3:
31 goes into 285 9 times with a remainder of 6.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 279 from 285 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 31

On to step 4:
63 divided by 31 is 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 92.0
The remainder is 1 after subtracting 62 from 63.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 31

Moving on to step 5:
The number 31 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 920.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 31

On to step 6:
If we divide 129 by 31, we get 4 and a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 9204.0
Deduct 124 from 129 and we're left 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.

Let's proceed to step 7:
50 divided by 31 is 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 9204.1
Deduct 31 from 50 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 8:
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: 9204.16
Subtracting 186 from 190 leaves us with 4.
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 9:
When dividing 40 by 31, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 9204.161
Subtract 31 from 40 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 10:
If we divide 90 by 31, we get 2 and a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 9204.1612
If we subtract 62 from 90, we 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.

Advancing to step 11:
280 divided by 31 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 9204.16129
Subtracting 279 from 280 leaves us 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.

Step 12:
31 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 9204.16129
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
31 goes into 100 3 times with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 9204.1612903
If we take 93 away from 100, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 14:
70 divided by 31 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 9204.16129032
Subtracting 62 from 70 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 9204.16129032, with a leftover of 8e-09.
