We look at the division of 6685079 by 648 
Let's see how many times 648 fits into 6685079.

Moving on to step 1:
6 divided by 648 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 648

Advancing to step 2:
648 can be fit into 66 0 times, resulting in a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 648

Going ahead to step 3:
If we divide 668 by 648, we get 1 and a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 648 from 668 leaves us with 20.
Bring next digit (5) of the dividend behind the 20 and repeat the process: 205 / 648

On to step 4:
205 divided by 648 is 0 with a remainder of 205.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 205, we get 205.
Fetch the next digit (0) from the dividend, attach it to 205 and continue: 2050 / 648

Going ahead to step 5:
648 can be fit into 2050 3 times, resulting in a remainder of 106.
Write down 3 as next digit of the result. 
Result so far: 103.0
Deduct 1944 from 2050 and we're left with 106.
Grab the next digit (7) from the dividend, add it to 106, then carry on: 1067 / 648

Step 6:
648 can be fit into 1067 1 times, resulting in a remainder of 419.
The next digit of our result is 1. 
Result so far: 1031.0
Subtract 648 from 1067 to get 419.
Grab the next digit (9) from the dividend, add it to 419, then carry on: 4199 / 648

Advancing to step 7:
4199 divided by 648 is 6 with a remainder of 311.
The number 6 becomes the next digit in our result. 
Result so far: 10316.0
If we subtract 3888 from 4199, we get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

On to step 8:
The number 648 fits into 3110 4 times, leaving a remainder of 518.
Write down 4 as next digit of the result. 
Result so far: 10316.4
If we subtract 2592 from 3110, we get 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

On to step 9:
When dividing 5180 by 648, we get 7 with a remainder of 644.
Record the quotient 7 as the next digit in the result. 
Result so far: 10316.47
Subtract 4536 from 5180 to get 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Advancing to step 10:
6440 divided by 648 is 9 with a remainder of 608.
The next digit of our result is 9. 
Result so far: 10316.479
Subtracting 5832 from 6440 leaves us with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Let's proceed to step 11:
If we divide 6080 by 648, we get 9 and a remainder of 248.
Record the quotient 9 as the next digit in the result. 
Result so far: 10316.4799
Subtract 5832 from 6080 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Our division results in 10316.4799 with a remaining 0.00248.
