We look at the division of 30122311 by 342 
Let's see how many times 342 fits into 30122311.

Going ahead to step 1:
342 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 342

Let's proceed to step 2:
30 divided by 342 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 342

Advancing to step 3:
If we divide 301 by 342, we get 0 and a remainder of 301.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 301, we get 301.
Append the next digit (2) from the dividend to 301 and continue with: 3012 / 342

On to step 4:
342 can be fit into 3012 8 times, resulting in a remainder of 276.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 2736 away from 3012, we end up with 276.
Grab the next digit (2) from the dividend, add it to 276, then carry on: 2762 / 342

On to step 5:
If we divide 2762 by 342, we get 8 and a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 88.0
Subtract 2736 from 2762 to get 26.
Grab the next digit (3) from the dividend, add it to 26, then carry on: 263 / 342

Let's proceed to step 6:
342 can be fit into 263 0 times, resulting in a remainder of 263.
Write down 0 as next digit of the result. 
Result so far: 880.0
The remainder is 263 after subtracting 0 from 263.
Append the next digit (1) from the dividend to 263 and continue with: 2631 / 342

Advancing to step 7:
342 goes into 2631 7 times with a remainder of 237.
The number 7 becomes the next digit in our result. 
Result so far: 8807.0
If we take 2394 away from 2631, we end up with 237.
Grab the next digit (1) from the dividend, add it to 237, then carry on: 2371 / 342

Going ahead to step 8:
When dividing 2371 by 342, we get 6 with a remainder of 319.
Record the quotient 6 as the next digit in the result. 
Result so far: 88076.0
Subtract 2052 from 2371 to get 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Advancing to step 9:
When dividing 3190 by 342, we get 9 with a remainder of 112.
The number 9 becomes the next digit in our result. 
Result so far: 88076.9
If we subtract 3078 from 3190, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 10:
The number 342 fits into 1120 3 times, leaving a remainder of 94.
The number 3 becomes the next digit in our result. 
Result so far: 88076.93
If we take 1026 away from 1120, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 11:
342 can be fit into 940 2 times, resulting in a remainder of 256.
Put 2 as the next digit of the answer. 
Result so far: 88076.932
The remainder is 256 after subtracting 684 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 12:
When dividing 2560 by 342, we get 7 with a remainder of 166.
The number 7 becomes the next digit in our result. 
Result so far: 88076.9327
Deduct 2394 from 2560 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Let's proceed to step 13:
The number 342 fits into 1660 4 times, leaving a remainder of 292.
Use 4 as the next digit of our solution. 
Result so far: 88076.93274
Subtracting 1368 from 1660 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Advancing to step 14:
The number 342 fits into 2920 8 times, leaving a remainder of 184.
Write down 8 as next digit of the result. 
Result so far: 88076.932748
Subtract 2736 from 2920 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 15:
342 can be fit into 1840 5 times, resulting in a remainder of 130.
Write down 5 as next digit of the result. 
Result so far: 88076.9327485
The remainder is 130 after subtracting 1710 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 16:
342 can be fit into 1300 3 times, resulting in a remainder of 274.
Put 3 as the next digit of the answer. 
Result so far: 88076.93274853
Subtract 1026 from 1300 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

In conclusion, the division gives 88076.93274853 with a balance of 2.74e-07.
