12346410 divided by 121 
We're looking to find how many times 121 goes into 12346410.

Step 1:
The number 121 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.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 121

Moving on to step 2:
When dividing 12 by 121, we get 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 121

On to step 3:
121 can be fit into 123 1 times, resulting in a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 2 after subtracting 121 from 123.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 121

Going ahead to step 4:
24 divided by 121 is 0 with a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 24, we end up with 24.
Bring next digit (6) of the dividend behind the 24 and repeat the process: 246 / 121

On to step 5:
The number 121 fits into 246 2 times, leaving a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
The remainder is 4 after subtracting 242 from 246.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 121

Moving on to step 6:
When dividing 44 by 121, we get 0 with a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 1020.0
If we subtract 0 from 44, we get 44.
Bring next digit (1) of the dividend behind the 44 and repeat the process: 441 / 121

Step 7:
The number 121 fits into 441 3 times, leaving a remainder of 78.
Record the quotient 3 as the next digit in the result. 
Result so far: 10203.0
If we take 363 away from 441, we end up with 78.
Include the next digit (0) from the dividend after 78, then repeat: 780 / 121

Step 8:
When dividing 780 by 121, we get 6 with a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 102036.0
If we subtract 726 from 780, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 9:
121 goes into 540 4 times with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 102036.4
The remainder is 56 after subtracting 484 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 10:
560 divided by 121 is 4 with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 102036.44
If we subtract 484 from 560, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

In conclusion, the division gives 102036.44 with a balance of 0.076.
