We divide 50889309 by 864
We want to divide 50889309 by 864.

Advancing to step 1:
5 divided by 864 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 864

On to step 2:
50 divided by 864 is 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Grab the next digit (8) from the dividend, add it to 50, then carry on: 508 / 864

Moving on to step 3:
The number 864 fits into 508 0 times, leaving a remainder of 508.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 508, we get 508.
Fetch the next digit (8) from the dividend, attach it to 508 and continue: 5088 / 864

Going ahead to step 4:
5088 divided by 864 is 5 with a remainder of 768.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 4320 from 5088 and we're left with 768.
Append the next digit (9) from the dividend to 768 and continue with: 7689 / 864

Moving on to step 5:
The number 864 fits into 7689 8 times, leaving a remainder of 777.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
Subtracting 6912 from 7689 leaves us with 777.
Take the next digit (3) from the dividend and append it to 777, then repeat: 7773 / 864

Advancing to step 6:
When dividing 7773 by 864, we get 8 with a remainder of 861.
The next digit of our result is 8. 
Result so far: 588.0
If we subtract 6912 from 7773, we get 861.
Bring next digit (0) of the dividend behind the 861 and repeat the process: 8610 / 864

Going ahead to step 7:
864 goes into 8610 9 times with a remainder of 834.
The next digit of our result is 9. 
Result so far: 5889.0
The remainder is 834 after subtracting 7776 from 8610.
Append the next digit (9) from the dividend to 834 and continue with: 8349 / 864

Moving on to step 8:
864 goes into 8349 9 times with a remainder of 573.
The number 9 becomes the next digit in our result. 
Result so far: 58899.0
Deduct 7776 from 8349 and we're left with 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Step 9:
864 goes into 5730 6 times with a remainder of 546.
The number 6 becomes the next digit in our result. 
Result so far: 58899.6
Deduct 5184 from 5730 and we're left with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

On to step 10:
864 can be fit into 5460 6 times, resulting in a remainder of 276.
Write down 6 as next digit of the result. 
Result so far: 58899.66
Deduct 5184 from 5460 and we're left with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

The final outcome is 58899.66, with a leftover of 0.276.
