121910 ÷ 48 
Let's see how many times 48 fits into 121910.

Going ahead to step 1:
The number 48 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 48

Moving on to step 2:
48 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 48

Going ahead to step 3:
If we divide 121 by 48, we get 2 and a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 96 from 121 and we're left with 25.
Bring next digit (9) of the dividend behind the 25 and repeat the process: 259 / 48

On to step 4:
48 goes into 259 5 times with a remainder of 19.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we take 240 away from 259, we end up with 19.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 48

On to step 5:
191 divided by 48 is 3 with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 253.0
If we subtract 144 from 191, we get 47.
Grab the next digit (0) from the dividend, add it to 47, then carry on: 470 / 48

Let's proceed to step 6:
48 goes into 470 9 times with a remainder of 38.
The next digit of our result is 9. 
Result so far: 2539.0
The remainder is 38 after subtracting 432 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 7:
The number 48 fits into 380 7 times, leaving a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 2539.7
Subtracting 336 from 380 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 8:
48 can be fit into 440 9 times, resulting in a remainder of 8.
The next digit of our result is 9. 
Result so far: 2539.79
If we take 432 away from 440, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
If we divide 80 by 48, we get 1 and a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 2539.791
Deduct 48 from 80 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.

Advancing to step 10:
When dividing 320 by 48, we get 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 2539.7916
The remainder is 32 after subtracting 288 from 320.
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 11:
48 can be fit into 320 6 times, resulting in a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 2539.79166
The remainder is 32 after subtracting 288 from 320.
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 2539.79166 with a balance of 3.2e-05.
