We look at the division of 145122 by 48 
Let's see how many times 48 fits into 145122.

Step 1:
48 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 48

Let's proceed to step 2:
14 divided by 48 is 0 with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 48

Advancing to step 3:
The number 48 fits into 145 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 144 from 145 and we're left with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 48

Going ahead to step 4:
48 can be fit into 11 0 times, resulting in a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
If we take 0 away from 11, we end up with 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 48

On to step 5:
48 can be fit into 112 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 302.0
If we subtract 96 from 112, we get 16.
Grab the next digit (2) from the dividend, add it to 16, then carry on: 162 / 48

Going ahead to step 6:
When dividing 162 by 48, we get 3 with a remainder of 18.
The next digit of our result is 3. 
Result so far: 3023.0
Subtracting 144 from 162 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
180 divided by 48 is 3 with a remainder of 36.
Use 3 as the next digit of our solution. 
Result so far: 3023.3
Subtract 144 from 180 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
48 goes into 360 7 times with a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 3023.37
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
If we divide 240 by 48, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 3023.375
Subtracting 240 from 240 leaves us 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.

Let's proceed to step 10:
48 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3023.375
If we take 0 away from 0, 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.

Advancing to step 11:
When dividing 0 by 48, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3023.375
If we take 0 away from 0, 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.

The quotient of the division is 3023.375, and the remainder is 0.0.
