23879321 divided by 342 
The aim is to understand the frequency of 342 in 23879321.

Moving on to step 1:
342 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 342

Going ahead to step 2:
23 divided by 342 is 0 with a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Include the next digit (8) from the dividend after 23, then repeat: 238 / 342

Moving on to step 3:
If we divide 238 by 342, we get 0 and a remainder of 238.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 238 and we're left with 238.
Fetch the next digit (7) from the dividend, attach it to 238 and continue: 2387 / 342

Step 4:
If we divide 2387 by 342, we get 6 and a remainder of 335.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 2052 from 2387 to get 335.
Fetch the next digit (9) from the dividend, attach it to 335 and continue: 3359 / 342

Step 5:
When dividing 3359 by 342, we get 9 with a remainder of 281.
Put 9 as the next digit of the answer. 
Result so far: 69.0
Subtract 3078 from 3359 to get 281.
Fetch the next digit (3) from the dividend, attach it to 281 and continue: 2813 / 342

Advancing to step 6:
342 goes into 2813 8 times with a remainder of 77.
Write down 8 as next digit of the result. 
Result so far: 698.0
Subtracting 2736 from 2813 leaves us with 77.
Append the next digit (2) from the dividend to 77 and continue with: 772 / 342

On to step 7:
The number 342 fits into 772 2 times, leaving a remainder of 88.
Write down 2 as next digit of the result. 
Result so far: 6982.0
Subtracting 684 from 772 leaves us with 88.
Include the next digit (1) from the dividend after 88, then repeat: 881 / 342

Moving on to step 8:
881 divided by 342 is 2 with a remainder of 197.
Write down 2 as next digit of the result. 
Result so far: 69822.0
Subtracting 684 from 881 leaves us with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Let's proceed to step 9:
The number 342 fits into 1970 5 times, leaving a remainder of 260.
Write down 5 as next digit of the result. 
Result so far: 69822.5
Subtract 1710 from 1970 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 10:
2600 divided by 342 is 7 with a remainder of 206.
Use 7 as the next digit of our solution. 
Result so far: 69822.57
Subtracting 2394 from 2600 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Let's proceed to step 11:
342 goes into 2060 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 69822.576
Subtracting 2052 from 2060 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
If we divide 80 by 342, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 69822.576
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 13:
If we divide 800 by 342, we get 2 and a remainder of 116.
The next digit of our result is 2. 
Result so far: 69822.57602
The remainder is 116 after subtracting 684 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 14:
342 goes into 1160 3 times with a remainder of 134.
Record the quotient 3 as the next digit in the result. 
Result so far: 69822.576023
If we subtract 1026 from 1160, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 15:
When dividing 1340 by 342, we get 3 with a remainder of 314.
Write down 3 as next digit of the result. 
Result so far: 69822.5760233
The remainder is 314 after subtracting 1026 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

The final outcome is 69822.5760233, with a leftover of 3.14e-06.
