We look at the division of 509465 by 48 
We want to divide 509465 by 48.

On to step 1:
When dividing 5 by 48, we get 0 with a remainder of 5.
The next digit of our result is 0. 
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

On to step 2:
50 divided by 48 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 48 from 50, we get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 48

Step 3:
The number 48 fits into 29 0 times, leaving a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 29 after subtracting 0 from 29.
Take the next digit (4) from the dividend and append it to 29, then repeat: 294 / 48

Let's proceed to step 4:
If we divide 294 by 48, we get 6 and a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 106.0
If we take 288 away from 294, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 48

Let's proceed to step 5:
66 divided by 48 is 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1061.0
Deduct 48 from 66 and we're left with 18.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 48

On to step 6:
When dividing 185 by 48, we get 3 with a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 10613.0
Deduct 144 from 185 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 7:
If we divide 410 by 48, we get 8 and a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 10613.8
Subtract 384 from 410 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
48 can be fit into 260 5 times, resulting in a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 10613.85
Subtract 240 from 260 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
48 can be fit into 200 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 10613.854
Deduct 192 from 200 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
When dividing 80 by 48, we get 1 with a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 10613.8541
Subtract 48 from 80 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 11:
If we divide 320 by 48, we get 6 and a remainder of 32.
The next digit of our result is 6. 
Result so far: 10613.85416
If we take 288 away from 320, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 12:
48 goes into 320 6 times with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 10613.854166
Subtracting 288 from 320 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 10613.854166, with a leftover of 3.2e-06.
