We look at the division of 50431133 by 858 
Our goal is to divide 50431133 by 858.

Advancing to step 1:
The number 858 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 858

Step 2:
858 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Append the next digit (4) from the dividend to 50 and continue with: 504 / 858

Moving on to step 3:
858 can be fit into 504 0 times, resulting in a remainder of 504.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 504 to get 504.
Bring next digit (3) of the dividend behind the 504 and repeat the process: 5043 / 858

Step 4:
The number 858 fits into 5043 5 times, leaving a remainder of 753.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 4290 from 5043 to get 753.
Include the next digit (1) from the dividend after 753, then repeat: 7531 / 858

On to step 5:
7531 divided by 858 is 8 with a remainder of 667.
The next digit of our result is 8. 
Result so far: 58.0
If we subtract 6864 from 7531, we get 667.
Fetch the next digit (1) from the dividend, attach it to 667 and continue: 6671 / 858

Let's proceed to step 6:
When dividing 6671 by 858, we get 7 with a remainder of 665.
Use 7 as the next digit of our solution. 
Result so far: 587.0
Deduct 6006 from 6671 and we're left with 665.
Take the next digit (3) from the dividend and append it to 665, then repeat: 6653 / 858

Advancing to step 7:
If we divide 6653 by 858, we get 7 and a remainder of 647.
Record the quotient 7 as the next digit in the result. 
Result so far: 5877.0
Deduct 6006 from 6653 and we're left with 647.
Grab the next digit (3) from the dividend, add it to 647, then carry on: 6473 / 858

Advancing to step 8:
The number 858 fits into 6473 7 times, leaving a remainder of 467.
Record the quotient 7 as the next digit in the result. 
Result so far: 58777.0
Subtracting 6006 from 6473 leaves us with 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Moving on to step 9:
858 goes into 4670 5 times with a remainder of 380.
Write down 5 as next digit of the result. 
Result so far: 58777.5
If we subtract 4290 from 4670, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 10:
858 can be fit into 3800 4 times, resulting in a remainder of 368.
Use 4 as the next digit of our solution. 
Result so far: 58777.54
If we take 3432 away from 3800, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Step 11:
The number 858 fits into 3680 4 times, leaving a remainder of 248.
Use 4 as the next digit of our solution. 
Result so far: 58777.544
Subtracting 3432 from 3680 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

In conclusion, the division gives 58777.544 with a balance of 0.0248.
