We look at the division of 121949 by 90 
Let's see how many times 90 fits into 121949.

Let's proceed to step 1:
90 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 90

On to step 2:
The number 90 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 90

Going ahead to step 3:
121 divided by 90 is 1 with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 31 after subtracting 90 from 121.
Bring next digit (9) of the dividend behind the 31 and repeat the process: 319 / 90

Step 4:
90 goes into 319 3 times with a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 270 from 319 and we're left with 49.
Include the next digit (4) from the dividend after 49, then repeat: 494 / 90

Step 5:
If we divide 494 by 90, we get 5 and a remainder of 44.
Use 5 as the next digit of our solution. 
Result so far: 135.0
The remainder is 44 after subtracting 450 from 494.
Grab the next digit (9) from the dividend, add it to 44, then carry on: 449 / 90

Advancing to step 6:
When dividing 449 by 90, we get 4 with a remainder of 89.
The number 4 becomes the next digit in our result. 
Result so far: 1354.0
Subtracting 360 from 449 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 7:
If we divide 890 by 90, we get 9 and a remainder of 80.
Use 9 as the next digit of our solution. 
Result so far: 1354.9
If we subtract 810 from 890, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 8:
90 can be fit into 800 8 times, resulting in a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 1354.98
Subtract 720 from 800 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 9:
90 can be fit into 800 8 times, resulting in a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 1354.988
If we subtract 720 from 800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

In conclusion, the division gives 1354.988 with a balance of 0.008.
