We're dividing 74290327 by 648 
We want to figure out the number of times 74290327 can be divided by 648.

On to step 1:
7 divided by 648 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 648

Advancing to step 2:
648 goes into 74 0 times with a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Append the next digit (2) from the dividend to 74 and continue with: 742 / 648

Moving on to step 3:
When dividing 742 by 648, we get 1 with a remainder of 94.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 648 from 742 to get 94.
Grab the next digit (9) from the dividend, add it to 94, then carry on: 949 / 648

Moving on to step 4:
949 divided by 648 is 1 with a remainder of 301.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 301 after subtracting 648 from 949.
Bring next digit (0) of the dividend behind the 301 and repeat the process: 3010 / 648

Moving on to step 5:
If we divide 3010 by 648, we get 4 and a remainder of 418.
The next digit of our result is 4. 
Result so far: 114.0
If we take 2592 away from 3010, we end up with 418.
Fetch the next digit (3) from the dividend, attach it to 418 and continue: 4183 / 648

Step 6:
648 goes into 4183 6 times with a remainder of 295.
The number 6 becomes the next digit in our result. 
Result so far: 1146.0
If we take 3888 away from 4183, we end up with 295.
Take the next digit (2) from the dividend and append it to 295, then repeat: 2952 / 648

Advancing to step 7:
When dividing 2952 by 648, we get 4 with a remainder of 360.
The next digit of our result is 4. 
Result so far: 11464.0
Subtract 2592 from 2952 to get 360.
Include the next digit (7) from the dividend after 360, then repeat: 3607 / 648

Going ahead to step 8:
When dividing 3607 by 648, we get 5 with a remainder of 367.
The number 5 becomes the next digit in our result. 
Result so far: 114645.0
The remainder is 367 after subtracting 3240 from 3607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Going ahead to step 9:
648 goes into 3670 5 times with a remainder of 430.
Use 5 as the next digit of our solution. 
Result so far: 114645.5
If we take 3240 away from 3670, we end up with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 10:
648 goes into 4300 6 times with a remainder of 412.
Put 6 as the next digit of the answer. 
Result so far: 114645.56
If we subtract 3888 from 4300, we get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Let's proceed to step 11:
648 goes into 4120 6 times with a remainder of 232.
The next digit of our result is 6. 
Result so far: 114645.566
If we subtract 3888 from 4120, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

The final outcome is 114645.566, with a leftover of 0.0232.
