We're dividing 648249 by 31 
We want to figure out the number of times 648249 can be divided by 31.

Step 1:
When dividing 6 by 31, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 31

Advancing to step 2:
31 goes into 64 2 times with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 62 from 64, we get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 31

Advancing to step 3:
When dividing 28 by 31, we get 0 with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtract 0 from 28 to get 28.
Fetch the next digit (2) from the dividend, attach it to 28 and continue: 282 / 31

Advancing to step 4:
31 can be fit into 282 9 times, resulting in a remainder of 3.
The next digit of our result is 9. 
Result so far: 209.0
Deduct 279 from 282 and we're left with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 31

On to step 5:
The number 31 fits into 34 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 2091.0
If we take 31 away from 34, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 31

Moving on to step 6:
31 goes into 39 1 times with a remainder of 8.
The next digit of our result is 1. 
Result so far: 20911.0
The remainder is 8 after subtracting 31 from 39.
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 7:
80 divided by 31 is 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 20911.2
If we subtract 62 from 80, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
180 divided by 31 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 20911.25
Subtract 155 from 180 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 9:
250 divided by 31 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 20911.258
If we subtract 248 from 250, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
20 divided by 31 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 20911.258
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
200 divided by 31 is 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 20911.25806
Subtract 186 from 200 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
31 can be fit into 140 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 20911.258064
Deduct 124 from 140 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
The number 31 fits into 160 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 20911.2580645
If we take 155 away from 160, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 14:
31 goes into 50 1 times with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 20911.25806451
If we take 31 away from 50, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

In conclusion, the division gives 20911.25806451 with a balance of 1.9e-08.
