50640810 ÷ 135 
Our goal is to divide 50640810 by 135.

Going ahead to step 1:
When dividing 5 by 135, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 135

On to step 2:
135 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Append the next digit (6) from the dividend to 50 and continue with: 506 / 135

Advancing to step 3:
506 divided by 135 is 3 with a remainder of 101.
The next digit of our result is 3. 
Result so far: 3.0
If we take 405 away from 506, we end up with 101.
Include the next digit (4) from the dividend after 101, then repeat: 1014 / 135

Moving on to step 4:
If we divide 1014 by 135, we get 7 and a remainder of 69.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
If we take 945 away from 1014, we end up with 69.
Grab the next digit (0) from the dividend, add it to 69, then carry on: 690 / 135

Let's proceed to step 5:
If we divide 690 by 135, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 375.0
If we subtract 675 from 690, we get 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 135

Step 6:
The number 135 fits into 158 1 times, leaving a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 3751.0
If we take 135 away from 158, we end up with 23.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 135

Going ahead to step 7:
The number 135 fits into 231 1 times, leaving a remainder of 96.
Use 1 as the next digit of our solution. 
Result so far: 37511.0
Subtracting 135 from 231 leaves us with 96.
Include the next digit (0) from the dividend after 96, then repeat: 960 / 135

Going ahead to step 8:
135 can be fit into 960 7 times, resulting in a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 375117.0
The remainder is 15 after subtracting 945 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 9:
150 divided by 135 is 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 375117.1
The remainder is 15 after subtracting 135 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
135 goes into 150 1 times with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 375117.11
Subtracting 135 from 150 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 375117.11, with a leftover of 0.015.
