We're dividing 13038606 by 648 
We want to divide 13038606 by 648.

Step 1:
When dividing 1 by 648, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 648

On to step 2:
The number 648 fits into 13 0 times, leaving a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 648

Moving on to step 3:
648 goes into 130 0 times with a remainder of 130.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 130, we end up with 130.
Bring next digit (3) of the dividend behind the 130 and repeat the process: 1303 / 648

Moving on to step 4:
The number 648 fits into 1303 2 times, leaving a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 1296 away from 1303, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 648

Advancing to step 5:
78 divided by 648 is 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 20.0
Subtracting 0 from 78 leaves us with 78.
Include the next digit (6) from the dividend after 78, then repeat: 786 / 648

Let's proceed to step 6:
The number 648 fits into 786 1 times, leaving a remainder of 138.
The next digit of our result is 1. 
Result so far: 201.0
If we take 648 away from 786, we end up with 138.
Take the next digit (0) from the dividend and append it to 138, then repeat: 1380 / 648

Going ahead to step 7:
1380 divided by 648 is 2 with a remainder of 84.
Write down 2 as next digit of the result. 
Result so far: 2012.0
Deduct 1296 from 1380 and we're left with 84.
Grab the next digit (6) from the dividend, add it to 84, then carry on: 846 / 648

Advancing to step 8:
648 can be fit into 846 1 times, resulting in a remainder of 198.
Put 1 as the next digit of the answer. 
Result so far: 20121.0
Subtract 648 from 846 to get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

On to step 9:
1980 divided by 648 is 3 with a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 20121.3
Subtracting 1944 from 1980 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
When dividing 360 by 648, we get 0 with a remainder of 360.
Write down 0 as next digit of the result. 
Result so far: 20121.3
If we take 0 away from 360, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 11:
The number 648 fits into 3600 5 times, leaving a remainder of 360.
The number 5 becomes the next digit in our result. 
Result so far: 20121.305
Deduct 3240 from 3600 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 12:
648 can be fit into 3600 5 times, resulting in a remainder of 360.
Write down 5 as next digit of the result. 
Result so far: 20121.3055
The remainder is 360 after subtracting 3240 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

In conclusion, the division gives 20121.3055 with a balance of 0.0036.
