Let's divide 12305843 by 342
We're looking to find how many times 342 goes into 12305843.

On to step 1:
If we divide 1 by 342, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 342

Let's proceed to step 2:
When dividing 12 by 342, we get 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 342

Let's proceed to step 3:
If we divide 123 by 342, we get 0 and a remainder of 123.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 123, we end up with 123.
Grab the next digit (0) from the dividend, add it to 123, then carry on: 1230 / 342

Going ahead to step 4:
1230 divided by 342 is 3 with a remainder of 204.
The next digit of our result is 3. 
Result so far: 3.0
If we take 1026 away from 1230, we end up with 204.
Grab the next digit (5) from the dividend, add it to 204, then carry on: 2045 / 342

On to step 5:
When dividing 2045 by 342, we get 5 with a remainder of 335.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
The remainder is 335 after subtracting 1710 from 2045.
Fetch the next digit (8) from the dividend, attach it to 335 and continue: 3358 / 342

Step 6:
342 goes into 3358 9 times with a remainder of 280.
Use 9 as the next digit of our solution. 
Result so far: 359.0
If we take 3078 away from 3358, we end up with 280.
Bring next digit (4) of the dividend behind the 280 and repeat the process: 2804 / 342

Going ahead to step 7:
When dividing 2804 by 342, we get 8 with a remainder of 68.
The next digit of our result is 8. 
Result so far: 3598.0
Deduct 2736 from 2804 and we're left with 68.
Append the next digit (3) from the dividend to 68 and continue with: 683 / 342

Moving on to step 8:
If we divide 683 by 342, we get 1 and a remainder of 341.
The number 1 becomes the next digit in our result. 
Result so far: 35981.0
Subtract 342 from 683 to get 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Let's proceed to step 9:
342 goes into 3410 9 times with a remainder of 332.
Put 9 as the next digit of the answer. 
Result so far: 35981.9
If we take 3078 away from 3410, we end up with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Moving on to step 10:
If we divide 3320 by 342, we get 9 and a remainder of 242.
Put 9 as the next digit of the answer. 
Result so far: 35981.99
Deduct 3078 from 3320 and we're left with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

In conclusion, the division gives 35981.99 with a balance of 0.242.
