Let's divide 209885 by 31
Our goal is to divide 209885 by 31.

Advancing to step 1:
31 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 31

On to step 2:
When dividing 20 by 31, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 31

Step 3:
The number 31 fits into 209 6 times, leaving a remainder of 23.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 186 from 209 to get 23.
Bring next digit (8) of the dividend behind the 23 and repeat the process: 238 / 31

Moving on to step 4:
When dividing 238 by 31, we get 7 with a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 67.0
Deduct 217 from 238 and we're left with 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 31

Let's proceed to step 5:
218 divided by 31 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 677.0
The remainder is 1 after subtracting 217 from 218.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 31

Step 6:
31 can be fit into 15 0 times, resulting in a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 6770.0
Subtract 0 from 15 to 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.

On to step 7:
150 divided by 31 is 4 with a remainder of 26.
The next digit of our result is 4. 
Result so far: 6770.4
Deduct 124 from 150 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
31 can be fit into 260 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 6770.48
The remainder is 12 after subtracting 248 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
If we divide 120 by 31, we get 3 and a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 6770.483
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 10:
When dividing 270 by 31, we get 8 with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 6770.4838
If we take 248 away from 270, we end up 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.

Moving on to step 11:
When dividing 220 by 31, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 6770.48387
Subtract 217 from 220 to get 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 12:
31 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 6770.48387
Subtract 0 from 30 to 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.

Moving on to step 13:
If we divide 300 by 31, we get 9 and a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 6770.4838709
If we subtract 279 from 300, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 14:
The number 31 fits into 210 6 times, leaving a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 6770.48387096
The remainder is 24 after subtracting 186 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 6770.48387096 with a remaining 2.4e-08.
