We're dividing 455138 by 50 
We want to divide 455138 by 50.

On to step 1:
50 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 50

Step 2:
50 can be fit into 45 0 times, resulting in a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Grab the next digit (5) from the dividend, add it to 45, then carry on: 455 / 50

Step 3:
If we divide 455 by 50, we get 9 and a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 450 from 455, we get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 50

Moving on to step 4:
If we divide 51 by 50, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
If we subtract 50 from 51, we get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 50

Moving on to step 5:
13 divided by 50 is 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 910.0
Subtract 0 from 13 to get 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 50

Advancing to step 6:
50 can be fit into 138 2 times, resulting in a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 9102.0
Deduct 100 from 138 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 7:
The number 50 fits into 380 7 times, leaving a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 9102.7
Subtract 350 from 380 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
When dividing 300 by 50, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 9102.76
Subtract 300 from 300 to 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.

Moving on to step 9:
When dividing 0 by 50, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9102.76
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.

Going ahead to step 10:
If we divide 0 by 50, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9102.76
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.

The final result is 9102.76 with a remainder of 0.0.
