50399356 ÷ 800 
We want to divide 50399356 by 800.

Let's proceed to step 1:
5 divided by 800 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 800

On to step 2:
800 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Include the next digit (3) from the dividend after 50, then repeat: 503 / 800

Going ahead to step 3:
When dividing 503 by 800, we get 0 with a remainder of 503.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 503 to get 503.
Fetch the next digit (9) from the dividend, attach it to 503 and continue: 5039 / 800

Moving on to step 4:
5039 divided by 800 is 6 with a remainder of 239.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 4800 from 5039 and we're left with 239.
Bring next digit (9) of the dividend behind the 239 and repeat the process: 2399 / 800

On to step 5:
If we divide 2399 by 800, we get 2 and a remainder of 799.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
If we subtract 1600 from 2399, we get 799.
Take the next digit (3) from the dividend and append it to 799, then repeat: 7993 / 800

Moving on to step 6:
The number 800 fits into 7993 9 times, leaving a remainder of 793.
Use 9 as the next digit of our solution. 
Result so far: 629.0
If we take 7200 away from 7993, we end up with 793.
Grab the next digit (5) from the dividend, add it to 793, then carry on: 7935 / 800

Let's proceed to step 7:
800 goes into 7935 9 times with a remainder of 735.
Write down 9 as next digit of the result. 
Result so far: 6299.0
Subtract 7200 from 7935 to get 735.
Include the next digit (6) from the dividend after 735, then repeat: 7356 / 800

Advancing to step 8:
800 goes into 7356 9 times with a remainder of 156.
Put 9 as the next digit of the answer. 
Result so far: 62999.0
If we take 7200 away from 7356, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 9:
800 goes into 1560 1 times with a remainder of 760.
Use 1 as the next digit of our solution. 
Result so far: 62999.1
If we take 800 away from 1560, we end up with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Moving on to step 10:
7600 divided by 800 is 9 with a remainder of 400.
Record the quotient 9 as the next digit in the result. 
Result so far: 62999.19
If we subtract 7200 from 7600, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 11:
800 can be fit into 4000 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 62999.195
Deduct 4000 from 4000 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
0 divided by 800 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 62999.195
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 13:
The number 800 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 62999.195
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 62999.195 with a balance of 0.0.
