We're dividing 48769007 by 648 
We want to divide 48769007 by 648.

On to step 1:
648 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 648

On to step 2:
648 goes into 48 0 times with a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 48 leaves us with 48.
Take the next digit (7) from the dividend and append it to 48, then repeat: 487 / 648

Let's proceed to step 3:
487 divided by 648 is 0 with a remainder of 487.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 487 leaves us with 487.
Include the next digit (6) from the dividend after 487, then repeat: 4876 / 648

Advancing to step 4:
648 can be fit into 4876 7 times, resulting in a remainder of 340.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 4536 from 4876 to get 340.
Include the next digit (9) from the dividend after 340, then repeat: 3409 / 648

Advancing to step 5:
3409 divided by 648 is 5 with a remainder of 169.
Use 5 as the next digit of our solution. 
Result so far: 75.0
If we subtract 3240 from 3409, we get 169.
Take the next digit (0) from the dividend and append it to 169, then repeat: 1690 / 648

On to step 6:
If we divide 1690 by 648, we get 2 and a remainder of 394.
The number 2 becomes the next digit in our result. 
Result so far: 752.0
If we subtract 1296 from 1690, we get 394.
Grab the next digit (0) from the dividend, add it to 394, then carry on: 3940 / 648

Moving on to step 7:
The number 648 fits into 3940 6 times, leaving a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 7526.0
Subtract 3888 from 3940 to get 52.
Append the next digit (7) from the dividend to 52 and continue with: 527 / 648

Advancing to step 8:
When dividing 527 by 648, we get 0 with a remainder of 527.
The next digit of our result is 0. 
Result so far: 75260.0
The remainder is 527 after subtracting 0 from 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

Moving on to step 9:
The number 648 fits into 5270 8 times, leaving a remainder of 86.
Put 8 as the next digit of the answer. 
Result so far: 75260.8
If we take 5184 away from 5270, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 10:
648 can be fit into 860 1 times, resulting in a remainder of 212.
Put 1 as the next digit of the answer. 
Result so far: 75260.81
If we subtract 648 from 860, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 11:
If we divide 2120 by 648, we get 3 and a remainder of 176.
The number 3 becomes the next digit in our result. 
Result so far: 75260.813
If we take 1944 away from 2120, we end up 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.

Let's proceed to step 12:
When dividing 1760 by 648, we get 2 with a remainder of 464.
The number 2 becomes the next digit in our result. 
Result so far: 75260.8132
Deduct 1296 from 1760 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.

Advancing to step 13:
If we divide 4640 by 648, we get 7 and a remainder of 104.
Use 7 as the next digit of our solution. 
Result so far: 75260.81327
Deduct 4536 from 4640 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 14:
The number 648 fits into 1040 1 times, leaving a remainder of 392.
The number 1 becomes the next digit in our result. 
Result so far: 75260.813271
Deduct 648 from 1040 and we're left with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Going ahead to step 15:
648 can be fit into 3920 6 times, resulting in a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 75260.8132716
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.

Going ahead to step 16:
The number 648 fits into 320 0 times, leaving a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 75260.8132716
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.

The final result is 75260.8132716 with a remainder of 3.2e-07.
