We look at the division of 687446 by 31 
We're looking to find how many times 31 goes into 687446.

Let's proceed to step 1:
If we divide 6 by 31, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 31

Going ahead to step 2:
31 can be fit into 68 2 times, resulting in a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 62 from 68 and we're left with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 31

Step 3:
31 goes into 67 2 times with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 22.0
Deduct 62 from 67 and we're left with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 31

On to step 4:
When dividing 54 by 31, we get 1 with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 221.0
Deduct 31 from 54 and we're left with 23.
Include the next digit (4) from the dividend after 23, then repeat: 234 / 31

Moving on to step 5:
31 goes into 234 7 times with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 2217.0
The remainder is 17 after subtracting 217 from 234.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 31

Advancing to step 6:
176 divided by 31 is 5 with a remainder of 21.
Write down 5 as next digit of the result. 
Result so far: 22175.0
If we take 155 away from 176, 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.

On to step 7:
210 divided by 31 is 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 22175.6
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.

Step 8:
31 goes into 240 7 times with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 22175.67
If we take 217 away from 240, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 9:
If we divide 230 by 31, we get 7 and a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 22175.677
Subtracting 217 from 230 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final outcome is 22175.677, with a leftover of 0.0013.
