We divide 40194517 by 648
We want to figure out the number of times 40194517 can be divided by 648.

Going ahead to step 1:
648 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 648

Advancing to step 2:
648 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Grab the next digit (1) from the dividend, add it to 40, then carry on: 401 / 648

Going ahead to step 3:
When dividing 401 by 648, we get 0 with a remainder of 401.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 401 after subtracting 0 from 401.
Include the next digit (9) from the dividend after 401, then repeat: 4019 / 648

Advancing to step 4:
648 goes into 4019 6 times with a remainder of 131.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 3888 from 4019 to get 131.
Append the next digit (4) from the dividend to 131 and continue with: 1314 / 648

Advancing to step 5:
The number 648 fits into 1314 2 times, leaving a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
Subtracting 1296 from 1314 leaves us with 18.
Fetch the next digit (5) from the dividend, attach it to 18 and continue: 185 / 648

Moving on to step 6:
648 can be fit into 185 0 times, resulting in a remainder of 185.
Put 0 as the next digit of the answer. 
Result so far: 620.0
Deduct 0 from 185 and we're left with 185.
Bring next digit (1) of the dividend behind the 185 and repeat the process: 1851 / 648

Advancing to step 7:
The number 648 fits into 1851 2 times, leaving a remainder of 555.
Use 2 as the next digit of our solution. 
Result so far: 6202.0
The remainder is 555 after subtracting 1296 from 1851.
Include the next digit (7) from the dividend after 555, then repeat: 5557 / 648

Let's proceed to step 8:
5557 divided by 648 is 8 with a remainder of 373.
Put 8 as the next digit of the answer. 
Result so far: 62028.0
If we subtract 5184 from 5557, we get 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Step 9:
648 goes into 3730 5 times with a remainder of 490.
The next digit of our result is 5. 
Result so far: 62028.5
If we take 3240 away from 3730, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 10:
648 goes into 4900 7 times with a remainder of 364.
The next digit of our result is 7. 
Result so far: 62028.57
If we subtract 4536 from 4900, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

On to step 11:
3640 divided by 648 is 5 with a remainder of 400.
The number 5 becomes the next digit in our result. 
Result so far: 62028.575
If we take 3240 away from 3640, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 12:
The number 648 fits into 4000 6 times, leaving a remainder of 112.
The number 6 becomes the next digit in our result. 
Result so far: 62028.5756
If we subtract 3888 from 4000, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 13:
648 can be fit into 1120 1 times, resulting in a remainder of 472.
Use 1 as the next digit of our solution. 
Result so far: 62028.57561
Subtracting 648 from 1120 leaves us with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Let's proceed to step 14:
When dividing 4720 by 648, we get 7 with a remainder of 184.
Record the quotient 7 as the next digit in the result. 
Result so far: 62028.575617
The remainder is 184 after subtracting 4536 from 4720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 15:
1840 divided by 648 is 2 with a remainder of 544.
The number 2 becomes the next digit in our result. 
Result so far: 62028.5756172
If we subtract 1296 from 1840, we get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Going ahead to step 16:
When dividing 5440 by 648, we get 8 with a remainder of 256.
The next digit of our result is 8. 
Result so far: 62028.57561728
If we take 5184 away from 5440, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The quotient of the division is 62028.57561728, and the remainder is 2.56e-07.
