79263575 divided by 648 
We want to divide 79263575 by 648.

On to step 1:
7 divided by 648 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 648

Step 2:
648 can be fit into 79 0 times, resulting in a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Append the next digit (2) from the dividend to 79 and continue with: 792 / 648

Moving on to step 3:
648 can be fit into 792 1 times, resulting in a remainder of 144.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 648 away from 792, we end up with 144.
Include the next digit (6) from the dividend after 144, then repeat: 1446 / 648

On to step 4:
648 can be fit into 1446 2 times, resulting in a remainder of 150.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 1296 from 1446 to get 150.
Grab the next digit (3) from the dividend, add it to 150, then carry on: 1503 / 648

Advancing to step 5:
If we divide 1503 by 648, we get 2 and a remainder of 207.
Write down 2 as next digit of the result. 
Result so far: 122.0
Subtracting 1296 from 1503 leaves us with 207.
Bring next digit (5) of the dividend behind the 207 and repeat the process: 2075 / 648

Advancing to step 6:
2075 divided by 648 is 3 with a remainder of 131.
Write down 3 as next digit of the result. 
Result so far: 1223.0
Subtracting 1944 from 2075 leaves us with 131.
Grab the next digit (7) from the dividend, add it to 131, then carry on: 1317 / 648

Let's proceed to step 7:
648 can be fit into 1317 2 times, resulting in a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 12232.0
Subtracting 1296 from 1317 leaves us with 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 648

Step 8:
648 can be fit into 215 0 times, resulting in a remainder of 215.
The next digit of our result is 0. 
Result so far: 122320.0
Subtracting 0 from 215 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

On to step 9:
The number 648 fits into 2150 3 times, leaving a remainder of 206.
The number 3 becomes the next digit in our result. 
Result so far: 122320.3
Subtracting 1944 from 2150 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Step 10:
648 can be fit into 2060 3 times, resulting in a remainder of 116.
Record the quotient 3 as the next digit in the result. 
Result so far: 122320.33
Subtract 1944 from 2060 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

After the division, we end up with 122320.33 and a remainder of 0.116.
