We look at the division of 660458 by 48 
We want to figure out the number of times 660458 can be divided by 48.

On to step 1:
6 divided by 48 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 48

Advancing to step 2:
66 divided by 48 is 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 18 after subtracting 48 from 66.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 48

Let's proceed to step 3:
48 can be fit into 180 3 times, resulting in a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 144 from 180, we get 36.
Take the next digit (4) from the dividend and append it to 36, then repeat: 364 / 48

Step 4:
48 can be fit into 364 7 times, resulting in a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 137.0
Subtract 336 from 364 to get 28.
Include the next digit (5) from the dividend after 28, then repeat: 285 / 48

Moving on to step 5:
48 goes into 285 5 times with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 1375.0
Deduct 240 from 285 and we're left with 45.
Include the next digit (8) from the dividend after 45, then repeat: 458 / 48

Moving on to step 6:
If we divide 458 by 48, we get 9 and a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 13759.0
If we take 432 away from 458, we end up with 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 7:
260 divided by 48 is 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 13759.5
Subtracting 240 from 260 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
48 goes into 200 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 13759.54
The remainder is 8 after subtracting 192 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
48 goes into 80 1 times with a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 13759.541
Subtracting 48 from 80 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.

Going ahead to step 10:
320 divided by 48 is 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 13759.5416
Deduct 288 from 320 and we're left 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.

Moving on to step 11:
When dividing 320 by 48, we get 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 13759.54166
Subtract 288 from 320 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.

In conclusion, the division gives 13759.54166 with a balance of 3.2e-05.
