Let's divide 42307736 by 648
Our goal is to divide 42307736 by 648.

Step 1:
When dividing 4 by 648, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 648

Advancing to step 2:
42 divided by 648 is 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Take the next digit (3) from the dividend and append it to 42, then repeat: 423 / 648

On to step 3:
648 can be fit into 423 0 times, resulting in a remainder of 423.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 423 after subtracting 0 from 423.
Bring next digit (0) of the dividend behind the 423 and repeat the process: 4230 / 648

On to step 4:
648 can be fit into 4230 6 times, resulting in a remainder of 342.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 3888 from 4230, we get 342.
Include the next digit (7) from the dividend after 342, then repeat: 3427 / 648

On to step 5:
When dividing 3427 by 648, we get 5 with a remainder of 187.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
If we take 3240 away from 3427, we end up with 187.
Bring next digit (7) of the dividend behind the 187 and repeat the process: 1877 / 648

On to step 6:
If we divide 1877 by 648, we get 2 and a remainder of 581.
Write down 2 as next digit of the result. 
Result so far: 652.0
The remainder is 581 after subtracting 1296 from 1877.
Take the next digit (3) from the dividend and append it to 581, then repeat: 5813 / 648

Step 7:
5813 divided by 648 is 8 with a remainder of 629.
The number 8 becomes the next digit in our result. 
Result so far: 6528.0
Subtracting 5184 from 5813 leaves us with 629.
Include the next digit (6) from the dividend after 629, then repeat: 6296 / 648

Step 8:
6296 divided by 648 is 9 with a remainder of 464.
Use 9 as the next digit of our solution. 
Result so far: 65289.0
Deduct 5832 from 6296 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Moving on to step 9:
648 can be fit into 4640 7 times, resulting in a remainder of 104.
The number 7 becomes the next digit in our result. 
Result so far: 65289.7
If we subtract 4536 from 4640, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 10:
1040 divided by 648 is 1 with a remainder of 392.
Record the quotient 1 as the next digit in the result. 
Result so far: 65289.71
Subtract 648 from 1040 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Let's proceed to step 11:
648 can be fit into 3920 6 times, resulting in a remainder of 32.
The next digit of our result is 6. 
Result so far: 65289.716
If we take 3888 away from 3920, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 12:
The number 648 fits into 320 0 times, leaving a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 65289.716
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 13:
3200 divided by 648 is 4 with a remainder of 608.
Use 4 as the next digit of our solution. 
Result so far: 65289.71604
Subtract 2592 from 3200 to get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Step 14:
When dividing 6080 by 648, we get 9 with a remainder of 248.
Put 9 as the next digit of the answer. 
Result so far: 65289.716049
If we subtract 5832 from 6080, we 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.

Going ahead to step 15:
The number 648 fits into 2480 3 times, leaving a remainder of 536.
Use 3 as the next digit of our solution. 
Result so far: 65289.7160493
Subtracting 1944 from 2480 leaves us with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Let's proceed to step 16:
648 goes into 5360 8 times with a remainder of 176.
The next digit of our result is 8. 
Result so far: 65289.71604938
Deduct 5184 from 5360 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

The quotient of the division is 65289.71604938, and the remainder is 1.76e-07.
