46243549 ÷ 648 
We want to figure out the number of times 46243549 can be divided by 648.

On to step 1:
When dividing 4 by 648, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 648

Going ahead to step 2:
648 can be fit into 46 0 times, resulting in a remainder of 46.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 46, we end up with 46.
Take the next digit (2) from the dividend and append it to 46, then repeat: 462 / 648

Advancing to step 3:
If we divide 462 by 648, we get 0 and a remainder of 462.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 462 to get 462.
Grab the next digit (4) from the dividend, add it to 462, then carry on: 4624 / 648

Advancing to step 4:
648 can be fit into 4624 7 times, resulting in a remainder of 88.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 4536 from 4624, we get 88.
Fetch the next digit (3) from the dividend, attach it to 88 and continue: 883 / 648

Let's proceed to step 5:
When dividing 883 by 648, we get 1 with a remainder of 235.
Write down 1 as next digit of the result. 
Result so far: 71.0
Subtracting 648 from 883 leaves us with 235.
Take the next digit (5) from the dividend and append it to 235, then repeat: 2355 / 648

Moving on to step 6:
The number 648 fits into 2355 3 times, leaving a remainder of 411.
Use 3 as the next digit of our solution. 
Result so far: 713.0
If we take 1944 away from 2355, we end up with 411.
Append the next digit (4) from the dividend to 411 and continue with: 4114 / 648

Going ahead to step 7:
When dividing 4114 by 648, we get 6 with a remainder of 226.
Use 6 as the next digit of our solution. 
Result so far: 7136.0
Subtracting 3888 from 4114 leaves us with 226.
Take the next digit (9) from the dividend and append it to 226, then repeat: 2269 / 648

Step 8:
If we divide 2269 by 648, we get 3 and a remainder of 325.
The number 3 becomes the next digit in our result. 
Result so far: 71363.0
The remainder is 325 after subtracting 1944 from 2269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Advancing to step 9:
When dividing 3250 by 648, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 71363.5
If we subtract 3240 from 3250, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
When dividing 100 by 648, we get 0 with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 71363.5
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 11:
The number 648 fits into 1000 1 times, leaving a remainder of 352.
Write down 1 as next digit of the result. 
Result so far: 71363.501
Subtract 648 from 1000 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 12:
The number 648 fits into 3520 5 times, leaving a remainder of 280.
The next digit of our result is 5. 
Result so far: 71363.5015
If we take 3240 away from 3520, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 13:
The number 648 fits into 2800 4 times, leaving a remainder of 208.
Put 4 as the next digit of the answer. 
Result so far: 71363.50154
If we take 2592 away from 2800, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 14:
2080 divided by 648 is 3 with a remainder of 136.
Use 3 as the next digit of our solution. 
Result so far: 71363.501543
Subtract 1944 from 2080 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 15:
The number 648 fits into 1360 2 times, leaving a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 71363.5015432
Subtract 1296 from 1360 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 16:
648 goes into 640 0 times with a remainder of 640.
Put 0 as the next digit of the answer. 
Result so far: 71363.5015432
If we take 0 away from 640, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

The quotient of the division is 71363.5015432, and the remainder is 6.4e-07.
