679992 ÷ 31 
We're looking to find how many times 31 goes into 679992.

Let's proceed to step 1:
If we divide 6 by 31, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 31

Step 2:
The number 31 fits into 67 2 times, leaving a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 62 from 67 leaves us with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 31

Advancing to step 3:
The number 31 fits into 59 1 times, leaving a remainder of 28.
The next digit of our result is 1. 
Result so far: 21.0
If we take 31 away from 59, we end up with 28.
Fetch the next digit (9) from the dividend, attach it to 28 and continue: 289 / 31

Step 4:
31 goes into 289 9 times with a remainder of 10.
The next digit of our result is 9. 
Result so far: 219.0
Deduct 279 from 289 and we're left with 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 31

Let's proceed to step 5:
109 divided by 31 is 3 with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 2193.0
Deduct 93 from 109 and we're left with 16.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 31

Let's proceed to step 6:
If we divide 162 by 31, we get 5 and a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 21935.0
Deduct 155 from 162 and we're left 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.

Step 7:
The number 31 fits into 70 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 21935.2
If we subtract 62 from 70, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
The number 31 fits into 80 2 times, leaving a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 21935.22
If we take 62 away from 80, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 21935.22 with a balance of 0.018.
