We look at the division of 202688 by 31 
We're looking to find how many times 31 goes into 202688.

On to step 1:
If we divide 2 by 31, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 31

On to step 2:
If we divide 20 by 31, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Grab the next digit (2) from the dividend, add it to 20, then carry on: 202 / 31

Step 3:
31 goes into 202 6 times with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 186 from 202 and we're left with 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 31

Advancing to step 4:
31 goes into 166 5 times with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
The remainder is 11 after subtracting 155 from 166.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 31

Step 5:
If we divide 118 by 31, we get 3 and a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 653.0
If we subtract 93 from 118, we get 25.
Bring next digit (8) of the dividend behind the 25 and repeat the process: 258 / 31

On to step 6:
31 goes into 258 8 times with a remainder of 10.
The next digit of our result is 8. 
Result so far: 6538.0
The remainder is 10 after subtracting 248 from 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
31 goes into 100 3 times with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 6538.3
If we subtract 93 from 100, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
31 goes into 70 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 6538.32
Deduct 62 from 70 and we're left 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.

Step 9:
31 goes into 80 2 times with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 6538.322
The remainder is 18 after subtracting 62 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 6538.322, and the remainder is 0.0018.
