We look at the division of 623958 by 31 
We want to figure out the number of times 623958 can be divided by 31.

Advancing to step 1:
The number 31 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 31

Let's proceed to step 2:
The number 31 fits into 62 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 0 after subtracting 62 from 62.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 31

Step 3:
When dividing 3 by 31, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtract 0 from 3 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 31

Going ahead to step 4:
31 can be fit into 39 1 times, resulting in a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 201.0
The remainder is 8 after subtracting 31 from 39.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 31

Let's proceed to step 5:
If we divide 85 by 31, we get 2 and a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 2012.0
Subtract 62 from 85 to get 23.
Fetch the next digit (8) from the dividend, attach it to 23 and continue: 238 / 31

Advancing to step 6:
31 can be fit into 238 7 times, resulting in a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 20127.0
Deduct 217 from 238 and we're left 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.

Let's proceed to step 7:
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: 20127.6
If we subtract 186 from 210, we get 24.
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:
If we divide 240 by 31, we get 7 and a remainder of 23.
The next digit of our result is 7. 
Result so far: 20127.67
Deduct 217 from 240 and we're left 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.

On to step 9:
If we divide 230 by 31, we get 7 and a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 20127.677
If we subtract 217 from 230, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

In conclusion, the division gives 20127.677 with a balance of 0.0013.
