50236993 divided by 649 
Our goal is to divide 50236993 by 649.

Step 1:
5 divided by 649 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 649

On to step 2:
50 divided by 649 is 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Grab the next digit (2) from the dividend, add it to 50, then carry on: 502 / 649

Moving on to step 3:
When dividing 502 by 649, we get 0 with a remainder of 502.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 502 to get 502.
Grab the next digit (3) from the dividend, add it to 502, then carry on: 5023 / 649

Step 4:
649 goes into 5023 7 times with a remainder of 480.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 4543 from 5023 leaves us with 480.
Bring next digit (6) of the dividend behind the 480 and repeat the process: 4806 / 649

On to step 5:
649 goes into 4806 7 times with a remainder of 263.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
If we take 4543 away from 4806, we end up with 263.
Bring next digit (9) of the dividend behind the 263 and repeat the process: 2639 / 649

On to step 6:
If we divide 2639 by 649, we get 4 and a remainder of 43.
The next digit of our result is 4. 
Result so far: 774.0
If we subtract 2596 from 2639, we get 43.
Take the next digit (9) from the dividend and append it to 43, then repeat: 439 / 649

Step 7:
When dividing 439 by 649, we get 0 with a remainder of 439.
Write down 0 as next digit of the result. 
Result so far: 7740.0
The remainder is 439 after subtracting 0 from 439.
Bring next digit (3) of the dividend behind the 439 and repeat the process: 4393 / 649

Step 8:
649 goes into 4393 6 times with a remainder of 499.
The number 6 becomes the next digit in our result. 
Result so far: 77406.0
Subtract 3894 from 4393 to get 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Advancing to step 9:
The number 649 fits into 4990 7 times, leaving a remainder of 447.
The next digit of our result is 7. 
Result so far: 77406.7
If we subtract 4543 from 4990, we get 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Going ahead to step 10:
649 can be fit into 4470 6 times, resulting in a remainder of 576.
The next digit of our result is 6. 
Result so far: 77406.76
If we take 3894 away from 4470, we end up with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Advancing to step 11:
5760 divided by 649 is 8 with a remainder of 568.
The number 8 becomes the next digit in our result. 
Result so far: 77406.768
Deduct 5192 from 5760 and we're left 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 12:
If we divide 5680 by 649, we get 8 and a remainder of 488.
The next digit of our result is 8. 
Result so far: 77406.7688
Subtract 5192 from 5680 to get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

The final outcome is 77406.7688, with a leftover of 0.00488.
