We're dividing 665278 by 48 
We want to figure out the number of times 665278 can be divided by 48.

On to step 1:
48 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 48

Going ahead to step 2:
When dividing 66 by 48, we get 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 48 from 66, we get 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 48

On to step 3:
185 divided by 48 is 3 with a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 144 from 185 to get 41.
Bring next digit (2) of the dividend behind the 41 and repeat the process: 412 / 48

Let's proceed to step 4:
412 divided by 48 is 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 138.0
The remainder is 28 after subtracting 384 from 412.
Bring next digit (7) of the dividend behind the 28 and repeat the process: 287 / 48

Moving on to step 5:
When dividing 287 by 48, we get 5 with a remainder of 47.
Use 5 as the next digit of our solution. 
Result so far: 1385.0
Subtracting 240 from 287 leaves us with 47.
Include the next digit (8) from the dividend after 47, then repeat: 478 / 48

Advancing to step 6:
If we divide 478 by 48, we get 9 and a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 13859.0
Subtracting 432 from 478 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 7:
The number 48 fits into 460 9 times, leaving a remainder of 28.
Write down 9 as next digit of the result. 
Result so far: 13859.9
If we take 432 away from 460, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 8:
If we divide 280 by 48, we get 5 and a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 13859.95
If we take 240 away from 280, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
48 can be fit into 400 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 13859.958
Deduct 384 from 400 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
160 divided by 48 is 3 with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 13859.9583
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
48 can be fit into 160 3 times, resulting in a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 13859.95833
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 13859.95833 with a remaining 1.6e-05.
