50129886 ÷ 458 
We want to figure out the number of times 50129886 can be divided by 458.

Step 1:
The number 458 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 458

Advancing to step 2:
When dividing 50 by 458, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Bring next digit (1) of the dividend behind the 50 and repeat the process: 501 / 458

Going ahead to step 3:
When dividing 501 by 458, we get 1 with a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 43 after subtracting 458 from 501.
Bring next digit (2) of the dividend behind the 43 and repeat the process: 432 / 458

Moving on to step 4:
458 goes into 432 0 times with a remainder of 432.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 432 leaves us with 432.
Take the next digit (9) from the dividend and append it to 432, then repeat: 4329 / 458

Moving on to step 5:
458 can be fit into 4329 9 times, resulting in a remainder of 207.
Write down 9 as next digit of the result. 
Result so far: 109.0
If we take 4122 away from 4329, we end up with 207.
Fetch the next digit (8) from the dividend, attach it to 207 and continue: 2078 / 458

Step 6:
2078 divided by 458 is 4 with a remainder of 246.
Put 4 as the next digit of the answer. 
Result so far: 1094.0
Subtracting 1832 from 2078 leaves us with 246.
Grab the next digit (8) from the dividend, add it to 246, then carry on: 2468 / 458

Moving on to step 7:
If we divide 2468 by 458, we get 5 and a remainder of 178.
The number 5 becomes the next digit in our result. 
Result so far: 10945.0
If we subtract 2290 from 2468, we get 178.
Append the next digit (6) from the dividend to 178 and continue with: 1786 / 458

Let's proceed to step 8:
458 goes into 1786 3 times with a remainder of 412.
The next digit of our result is 3. 
Result so far: 109453.0
The remainder is 412 after subtracting 1374 from 1786.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Let's proceed to step 9:
When dividing 4120 by 458, we get 8 with a remainder of 456.
Record the quotient 8 as the next digit in the result. 
Result so far: 109453.8
The remainder is 456 after subtracting 3664 from 4120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Step 10:
4560 divided by 458 is 9 with a remainder of 438.
The number 9 becomes the next digit in our result. 
Result so far: 109453.89
Subtracting 4122 from 4560 leaves us with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Step 11:
The number 458 fits into 4380 9 times, leaving a remainder of 258.
Put 9 as the next digit of the answer. 
Result so far: 109453.899
The remainder is 258 after subtracting 4122 from 4380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

In conclusion, the division gives 109453.899 with a balance of 0.0258.
