Let's divide 510189 by 50
Let's see how many times 50 fits into 510189.

On to step 1:
The number 50 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 50

Moving on to step 2:
The number 50 fits into 51 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 50 from 51, we get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 50

On to step 3:
50 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 10, we end up with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 50

Let's proceed to step 4:
50 goes into 101 2 times with a remainder of 1.
The next digit of our result is 2. 
Result so far: 102.0
Subtracting 100 from 101 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 50

Let's proceed to step 5:
The number 50 fits into 18 0 times, leaving a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 1020.0
Subtracting 0 from 18 leaves us with 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 50

On to step 6:
The number 50 fits into 189 3 times, leaving a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 10203.0
The remainder is 39 after subtracting 150 from 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
If we divide 390 by 50, we get 7 and a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 10203.7
Subtract 350 from 390 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
50 goes into 400 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 10203.78
If we take 400 away from 400, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
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: 10203.78
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
If we divide 0 by 50, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10203.78
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 10203.78 with a balance of 0.0.
