We look at the division of 507138 by 50 
We're looking to find how many times 50 goes into 507138.

Advancing to step 1:
5 divided by 50 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 50

Advancing to step 2:
50 can be fit into 50 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 50 from 50 to get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 50

Let's proceed to step 3:
When dividing 7 by 50, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 7 to get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 50

Let's proceed to step 4:
50 can be fit into 71 1 times, resulting in a remainder of 21.
The next digit of our result is 1. 
Result so far: 101.0
Deduct 50 from 71 and we're left with 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 50

Let's proceed to step 5:
213 divided by 50 is 4 with a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 1014.0
Deduct 200 from 213 and we're left with 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 50

Let's proceed to step 6:
If we divide 138 by 50, we get 2 and a remainder of 38.
The next digit of our result is 2. 
Result so far: 10142.0
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: 10142.7
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.

Advancing to step 8:
If we divide 300 by 50, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 10142.76
The remainder is 0 after subtracting 300 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
50 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10142.76
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.

Step 10:
When dividing 0 by 50, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10142.76
Subtract 0 from 0 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.

After the division, we end up with 10142.76 and a remainder of 0.0.
