Let's divide 49742286 by 648
We want to figure out the number of times 49742286 can be divided by 648.

Step 1:
4 divided by 648 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 648

Advancing to step 2:
648 goes into 49 0 times with a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 49 and we're left with 49.
Bring next digit (7) of the dividend behind the 49 and repeat the process: 497 / 648

Advancing to step 3:
When dividing 497 by 648, we get 0 with a remainder of 497.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 497 leaves us with 497.
Take the next digit (4) from the dividend and append it to 497, then repeat: 4974 / 648

On to step 4:
648 goes into 4974 7 times with a remainder of 438.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 438 after subtracting 4536 from 4974.
Fetch the next digit (2) from the dividend, attach it to 438 and continue: 4382 / 648

Step 5:
If we divide 4382 by 648, we get 6 and a remainder of 494.
The next digit of our result is 6. 
Result so far: 76.0
Deduct 3888 from 4382 and we're left with 494.
Grab the next digit (2) from the dividend, add it to 494, then carry on: 4942 / 648

Going ahead to step 6:
When dividing 4942 by 648, we get 7 with a remainder of 406.
Write down 7 as next digit of the result. 
Result so far: 767.0
Subtract 4536 from 4942 to get 406.
Fetch the next digit (8) from the dividend, attach it to 406 and continue: 4068 / 648

Let's proceed to step 7:
4068 divided by 648 is 6 with a remainder of 180.
The number 6 becomes the next digit in our result. 
Result so far: 7676.0
Subtracting 3888 from 4068 leaves us with 180.
Include the next digit (6) from the dividend after 180, then repeat: 1806 / 648

Let's proceed to step 8:
If we divide 1806 by 648, we get 2 and a remainder of 510.
The next digit of our result is 2. 
Result so far: 76762.0
If we take 1296 away from 1806, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

On to step 9:
5100 divided by 648 is 7 with a remainder of 564.
The next digit of our result is 7. 
Result so far: 76762.7
If we take 4536 away from 5100, we end up with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

On to step 10:
648 can be fit into 5640 8 times, resulting in a remainder of 456.
Put 8 as the next digit of the answer. 
Result so far: 76762.78
Subtract 5184 from 5640 to get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Let's proceed to step 11:
648 can be fit into 4560 7 times, resulting in a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 76762.787
Subtracting 4536 from 4560 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
648 can be fit into 240 0 times, resulting in a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 76762.787
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 13:
648 can be fit into 2400 3 times, resulting in a remainder of 456.
The number 3 becomes the next digit in our result. 
Result so far: 76762.78703
If we take 1944 away from 2400, we end up with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Advancing to step 14:
648 can be fit into 4560 7 times, resulting in a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 76762.787037
Deduct 4536 from 4560 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 15:
648 goes into 240 0 times with a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 76762.787037
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 16:
648 can be fit into 2400 3 times, resulting in a remainder of 456.
Record the quotient 3 as the next digit in the result. 
Result so far: 76762.78703703
Subtracting 1944 from 2400 leaves us with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

The final outcome is 76762.78703703, with a leftover of 4.56e-07.
