67421349 divided by 648 
We're looking to find how many times 648 goes into 67421349.

Advancing to step 1:
The number 648 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 648

Moving on to step 2:
648 goes into 67 0 times with a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 67 leaves us with 67.
Bring next digit (4) of the dividend behind the 67 and repeat the process: 674 / 648

Step 3:
When dividing 674 by 648, we get 1 with a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 648 away from 674, we end up with 26.
Fetch the next digit (2) from the dividend, attach it to 26 and continue: 262 / 648

Let's proceed to step 4:
The number 648 fits into 262 0 times, leaving a remainder of 262.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 262 to get 262.
Include the next digit (1) from the dividend after 262, then repeat: 2621 / 648

Let's proceed to step 5:
When dividing 2621 by 648, we get 4 with a remainder of 29.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
If we take 2592 away from 2621, we end up with 29.
Fetch the next digit (3) from the dividend, attach it to 29 and continue: 293 / 648

Step 6:
648 can be fit into 293 0 times, resulting in a remainder of 293.
Use 0 as the next digit of our solution. 
Result so far: 1040.0
Subtracting 0 from 293 leaves us with 293.
Fetch the next digit (4) from the dividend, attach it to 293 and continue: 2934 / 648

Going ahead to step 7:
When dividing 2934 by 648, we get 4 with a remainder of 342.
The next digit of our result is 4. 
Result so far: 10404.0
The remainder is 342 after subtracting 2592 from 2934.
Grab the next digit (9) from the dividend, add it to 342, then carry on: 3429 / 648

Advancing to step 8:
The number 648 fits into 3429 5 times, leaving a remainder of 189.
Use 5 as the next digit of our solution. 
Result so far: 104045.0
Deduct 3240 from 3429 and we're left with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Advancing to step 9:
648 goes into 1890 2 times with a remainder of 594.
Record the quotient 2 as the next digit in the result. 
Result so far: 104045.2
If we take 1296 away from 1890, we end up with 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Let's proceed to step 10:
When dividing 5940 by 648, we get 9 with a remainder of 108.
Write down 9 as next digit of the result. 
Result so far: 104045.29
Deduct 5832 from 5940 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 11:
648 goes into 1080 1 times with a remainder of 432.
Use 1 as the next digit of our solution. 
Result so far: 104045.291
Subtracting 648 from 1080 leaves us with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Step 12:
4320 divided by 648 is 6 with a remainder of 432.
Record the quotient 6 as the next digit in the result. 
Result so far: 104045.2916
The remainder is 432 after subtracting 3888 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Advancing to step 13:
If we divide 4320 by 648, we get 6 and a remainder of 432.
Put 6 as the next digit of the answer. 
Result so far: 104045.29166
If we take 3888 away from 4320, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

After the division, we end up with 104045.29166 and a remainder of 0.000432.
