54064378 ÷ 648 
We're looking to find how many times 648 goes into 54064378.

Let's proceed to step 1:
5 divided by 648 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 648

Let's proceed to step 2:
648 goes into 54 0 times with a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Fetch the next digit (0) from the dividend, attach it to 54 and continue: 540 / 648

Step 3:
When dividing 540 by 648, we get 0 with a remainder of 540.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 540, we get 540.
Take the next digit (6) from the dividend and append it to 540, then repeat: 5406 / 648

Moving on to step 4:
When dividing 5406 by 648, we get 8 with a remainder of 222.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 5184 from 5406, we get 222.
Include the next digit (4) from the dividend after 222, then repeat: 2224 / 648

Going ahead to step 5:
The number 648 fits into 2224 3 times, leaving a remainder of 280.
Write down 3 as next digit of the result. 
Result so far: 83.0
If we subtract 1944 from 2224, we get 280.
Take the next digit (3) from the dividend and append it to 280, then repeat: 2803 / 648

Moving on to step 6:
2803 divided by 648 is 4 with a remainder of 211.
Use 4 as the next digit of our solution. 
Result so far: 834.0
Deduct 2592 from 2803 and we're left with 211.
Grab the next digit (7) from the dividend, add it to 211, then carry on: 2117 / 648

On to step 7:
When dividing 2117 by 648, we get 3 with a remainder of 173.
The number 3 becomes the next digit in our result. 
Result so far: 8343.0
Subtracting 1944 from 2117 leaves us with 173.
Take the next digit (8) from the dividend and append it to 173, then repeat: 1738 / 648

On to step 8:
1738 divided by 648 is 2 with a remainder of 442.
The number 2 becomes the next digit in our result. 
Result so far: 83432.0
If we subtract 1296 from 1738, we get 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Moving on to step 9:
648 goes into 4420 6 times with a remainder of 532.
Use 6 as the next digit of our solution. 
Result so far: 83432.6
Deduct 3888 from 4420 and we're left with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Moving on to step 10:
The number 648 fits into 5320 8 times, leaving a remainder of 136.
Use 8 as the next digit of our solution. 
Result so far: 83432.68
Deduct 5184 from 5320 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 11:
648 can be fit into 1360 2 times, resulting in a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 83432.682
Deduct 1296 from 1360 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
When dividing 640 by 648, we get 0 with a remainder of 640.
The number 0 becomes the next digit in our result. 
Result so far: 83432.682
If we subtract 0 from 640, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 13:
6400 divided by 648 is 9 with a remainder of 568.
Use 9 as the next digit of our solution. 
Result so far: 83432.68209
Subtracting 5832 from 6400 leaves us with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

On to step 14:
If we divide 5680 by 648, we get 8 and a remainder of 496.
The number 8 becomes the next digit in our result. 
Result so far: 83432.682098
Subtract 5184 from 5680 to get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

On to step 15:
When dividing 4960 by 648, we get 7 with a remainder of 424.
Put 7 as the next digit of the answer. 
Result so far: 83432.6820987
Subtracting 4536 from 4960 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

On to step 16:
When dividing 4240 by 648, we get 6 with a remainder of 352.
Write down 6 as next digit of the result. 
Result so far: 83432.68209876
Subtracting 3888 from 4240 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Our division results in 83432.68209876 with a remaining 3.52e-07.
