We divide 16687923 by 648
We want to divide 16687923 by 648.

Moving on to step 1:
When dividing 1 by 648, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 648

Step 2:
648 can be fit into 16 0 times, resulting in a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 648

On to step 3:
648 can be fit into 166 0 times, resulting in a remainder of 166.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 166, we end up with 166.
Fetch the next digit (8) from the dividend, attach it to 166 and continue: 1668 / 648

Moving on to step 4:
The number 648 fits into 1668 2 times, leaving a remainder of 372.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1296 from 1668 leaves us with 372.
Grab the next digit (7) from the dividend, add it to 372, then carry on: 3727 / 648

Advancing to step 5:
3727 divided by 648 is 5 with a remainder of 487.
The next digit of our result is 5. 
Result so far: 25.0
Subtracting 3240 from 3727 leaves us with 487.
Fetch the next digit (9) from the dividend, attach it to 487 and continue: 4879 / 648

Advancing to step 6:
The number 648 fits into 4879 7 times, leaving a remainder of 343.
Record the quotient 7 as the next digit in the result. 
Result so far: 257.0
Subtract 4536 from 4879 to get 343.
Bring next digit (2) of the dividend behind the 343 and repeat the process: 3432 / 648

Going ahead to step 7:
If we divide 3432 by 648, we get 5 and a remainder of 192.
Use 5 as the next digit of our solution. 
Result so far: 2575.0
Subtract 3240 from 3432 to get 192.
Grab the next digit (3) from the dividend, add it to 192, then carry on: 1923 / 648

Let's proceed to step 8:
When dividing 1923 by 648, we get 2 with a remainder of 627.
Write down 2 as next digit of the result. 
Result so far: 25752.0
Subtracting 1296 from 1923 leaves us with 627.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

Step 9:
When dividing 6270 by 648, we get 9 with a remainder of 438.
The number 9 becomes the next digit in our result. 
Result so far: 25752.9
Subtract 5832 from 6270 to get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Step 10:
When dividing 4380 by 648, we get 6 with a remainder of 492.
Use 6 as the next digit of our solution. 
Result so far: 25752.96
Subtracting 3888 from 4380 leaves us with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Going ahead to step 11:
The number 648 fits into 4920 7 times, leaving a remainder of 384.
Record the quotient 7 as the next digit in the result. 
Result so far: 25752.967
Subtracting 4536 from 4920 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 12:
3840 divided by 648 is 5 with a remainder of 600.
The number 5 becomes the next digit in our result. 
Result so far: 25752.9675
The remainder is 600 after subtracting 3240 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 13:
When dividing 6000 by 648, we get 9 with a remainder of 168.
Record the quotient 9 as the next digit in the result. 
Result so far: 25752.96759
Subtracting 5832 from 6000 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 14:
648 goes into 1680 2 times with a remainder of 384.
The next digit of our result is 2. 
Result so far: 25752.967592
If we subtract 1296 from 1680, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 15:
If we divide 3840 by 648, we get 5 and a remainder of 600.
Write down 5 as next digit of the result. 
Result so far: 25752.9675925
Deduct 3240 from 3840 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 16:
648 can be fit into 6000 9 times, resulting in a remainder of 168.
Put 9 as the next digit of the answer. 
Result so far: 25752.96759259
Deduct 5832 from 6000 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

In conclusion, the division gives 25752.96759259 with a balance of 1.68e-07.
