We're dividing 66663 by 48 
We want to figure out the number of times 66663 can be divided by 48.

Step 1:
The number 48 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 48

Let's proceed to step 2:
48 goes into 66 1 times with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 48 from 66 to get 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 48

Advancing to step 3:
48 can be fit into 186 3 times, resulting in a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 144 from 186 and we're left with 42.
Fetch the next digit (6) from the dividend, attach it to 42 and continue: 426 / 48

On to step 4:
When dividing 426 by 48, we get 8 with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 138.0
Deduct 384 from 426 and we're left with 42.
Append the next digit (3) from the dividend to 42 and continue with: 423 / 48

Let's proceed to step 5:
If we divide 423 by 48, we get 8 and a remainder of 39.
The next digit of our result is 8. 
Result so far: 1388.0
If we subtract 384 from 423, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on 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: 1388.8
Subtract 384 from 390 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
48 goes into 60 1 times with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1388.81
If we take 48 away from 60, we end up 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.

Let's proceed to step 8:
If we divide 120 by 48, we get 2 and a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 1388.812
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:
240 divided by 48 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 1388.8125
If we take 240 away from 240, 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 10:
48 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1388.8125
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.

Let's proceed to step 11:
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: 1388.8125
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.

The final outcome is 1388.8125, with a leftover of 0.0.
