We're dividing 613920 by 48 
Let's see how many times 48 fits into 613920.

On to step 1:
If we divide 6 by 48, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 48

Advancing to step 2:
48 goes into 61 1 times with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 48 from 61 and we're left with 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 48

Going ahead to step 3:
The number 48 fits into 133 2 times, leaving a remainder of 37.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 37 after subtracting 96 from 133.
Include the next digit (9) from the dividend after 37, then repeat: 379 / 48

Advancing to step 4:
When dividing 379 by 48, we get 7 with a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 127.0
Subtract 336 from 379 to get 43.
Include the next digit (2) from the dividend after 43, then repeat: 432 / 48

Going ahead to step 5:
48 can be fit into 432 9 times, resulting in a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 1279.0
Subtract 432 from 432 to get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 48

Step 6:
When dividing 0 by 48, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12790.0
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.

Going ahead to step 7:
0 divided by 48 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12790.0
The remainder is 0 after subtracting 0 from 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 8:
0 divided by 48 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12790.0
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.

The final outcome is 12790.0, with a leftover of 0.0.
