We look at the division of 509670 by 48 
Let's see how many times 48 fits into 509670.

Let's proceed to step 1:
48 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
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 / 48

Let's proceed to step 2:
48 goes into 50 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 48 from 50, we get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 48

Going ahead to step 3:
When dividing 29 by 48, we get 0 with a remainder of 29.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 29 leaves us with 29.
Fetch the next digit (6) from the dividend, attach it to 29 and continue: 296 / 48

Advancing to step 4:
When dividing 296 by 48, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 106.0
If we subtract 288 from 296, we get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 48

Advancing to step 5:
48 goes into 87 1 times with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 1061.0
Deduct 48 from 87 and we're left with 39.
Take the next digit (0) from the dividend and append it to 39, then repeat: 390 / 48

Going ahead to step 6:
If we divide 390 by 48, we get 8 and a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 10618.0
Deduct 384 from 390 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
60 divided by 48 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 10618.1
Deduct 48 from 60 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
If we divide 120 by 48, we get 2 and a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 10618.12
If we take 96 away from 120, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
When dividing 240 by 48, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 10618.125
Deduct 240 from 240 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.

Step 10:
48 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10618.125
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.

Moving on to step 11:
When dividing 0 by 48, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10618.125
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.

The final result is 10618.125 with a remainder of 0.0.
