We look at the division of 31686865 by 690 
We want to figure out the number of times 31686865 can be divided by 690.

Going ahead to step 1:
3 divided by 690 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 690

Going ahead to step 2:
The number 690 fits into 31 0 times, leaving a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Fetch the next digit (6) from the dividend, attach it to 31 and continue: 316 / 690

Going ahead to step 3:
316 divided by 690 is 0 with a remainder of 316.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 316, we end up with 316.
Fetch the next digit (8) from the dividend, attach it to 316 and continue: 3168 / 690

Let's proceed to step 4:
The number 690 fits into 3168 4 times, leaving a remainder of 408.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 2760 from 3168 to get 408.
Include the next digit (6) from the dividend after 408, then repeat: 4086 / 690

Let's proceed to step 5:
The number 690 fits into 4086 5 times, leaving a remainder of 636.
Use 5 as the next digit of our solution. 
Result so far: 45.0
If we subtract 3450 from 4086, we get 636.
Include the next digit (8) from the dividend after 636, then repeat: 6368 / 690

Going ahead to step 6:
When dividing 6368 by 690, we get 9 with a remainder of 158.
Record the quotient 9 as the next digit in the result. 
Result so far: 459.0
If we take 6210 away from 6368, we end up with 158.
Include the next digit (6) from the dividend after 158, then repeat: 1586 / 690

On to step 7:
1586 divided by 690 is 2 with a remainder of 206.
Record the quotient 2 as the next digit in the result. 
Result so far: 4592.0
The remainder is 206 after subtracting 1380 from 1586.
Bring next digit (5) of the dividend behind the 206 and repeat the process: 2065 / 690

Going ahead to step 8:
690 goes into 2065 2 times with a remainder of 685.
Record the quotient 2 as the next digit in the result. 
Result so far: 45922.0
If we subtract 1380 from 2065, we get 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Step 9:
If we divide 6850 by 690, we get 9 and a remainder of 640.
The number 9 becomes the next digit in our result. 
Result so far: 45922.9
If we take 6210 away from 6850, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 10:
690 goes into 6400 9 times with a remainder of 190.
Record the quotient 9 as the next digit in the result. 
Result so far: 45922.99
Subtract 6210 from 6400 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Our division results in 45922.99 with a remaining 0.19.
