123900 ÷ 48 
Let's see how many times 48 fits into 123900.

Advancing to step 1:
48 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 48

On to step 2:
When dividing 12 by 48, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 48

Moving on to step 3:
48 can be fit into 123 2 times, resulting in a remainder of 27.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 96 from 123 and we're left with 27.
Append the next digit (9) from the dividend to 27 and continue with: 279 / 48

Going ahead to step 4:
When dividing 279 by 48, we get 5 with a remainder of 39.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we subtract 240 from 279, we get 39.
Fetch the next digit (0) from the dividend, attach it to 39 and continue: 390 / 48

Advancing to step 5:
390 divided by 48 is 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 258.0
Deduct 384 from 390 and we're left with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 48

Moving on to step 6:
48 can be fit into 60 1 times, resulting in a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 2581.0
Subtracting 48 from 60 leaves us 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.

Step 7:
48 can be fit into 120 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 2581.2
If we subtract 96 from 120, we 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.

Going ahead to step 8:
If we divide 240 by 48, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 2581.25
Deduct 240 from 240 and we're left 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.

On to step 9:
48 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2581.25
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 10:
48 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2581.25
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.

Our division results in 2581.25 with a remaining 0.0.
