We're dividing 30493905 by 121 
We want to divide 30493905 by 121.

Let's proceed to step 1:
When dividing 3 by 121, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 121

Moving on to step 2:
The number 121 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Include the next digit (4) from the dividend after 30, then repeat: 304 / 121

On to step 3:
121 can be fit into 304 2 times, resulting in a remainder of 62.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 242 from 304 to get 62.
Append the next digit (9) from the dividend to 62 and continue with: 629 / 121

On to step 4:
The number 121 fits into 629 5 times, leaving a remainder of 24.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Deduct 605 from 629 and we're left with 24.
Append the next digit (3) from the dividend to 24 and continue with: 243 / 121

Advancing to step 5:
The number 121 fits into 243 2 times, leaving a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 252.0
If we take 242 away from 243, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 121

Advancing to step 6:
121 goes into 19 0 times with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 2520.0
If we take 0 away from 19, we end up with 19.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 121

Moving on to step 7:
121 goes into 190 1 times with a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 25201.0
Subtracting 121 from 190 leaves us with 69.
Include the next digit (5) from the dividend after 69, then repeat: 695 / 121

Advancing to step 8:
695 divided by 121 is 5 with a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 252015.0
Subtract 605 from 695 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 9:
The number 121 fits into 900 7 times, leaving a remainder of 53.
The next digit of our result is 7. 
Result so far: 252015.7
Subtracting 847 from 900 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 10:
The number 121 fits into 530 4 times, leaving a remainder of 46.
The next digit of our result is 4. 
Result so far: 252015.74
If we take 484 away from 530, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 11:
121 goes into 460 3 times with a remainder of 97.
Use 3 as the next digit of our solution. 
Result so far: 252015.743
Subtracting 363 from 460 leaves us with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Let's proceed to step 12:
The number 121 fits into 970 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 252015.7438
The remainder is 2 after subtracting 968 from 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
20 divided by 121 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 252015.7438
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
121 can be fit into 200 1 times, resulting in a remainder of 79.
Write down 1 as next digit of the result. 
Result so far: 252015.743801
Subtract 121 from 200 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 15:
121 goes into 790 6 times with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 252015.7438016
The remainder is 64 after subtracting 726 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 16:
The number 121 fits into 640 5 times, leaving a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 252015.74380165
If we take 605 away from 640, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

In conclusion, the division gives 252015.74380165 with a balance of 3.5e-08.
